The aim of this study was to evaluate the effects of irrigation water polluted with nickel on the growth of <em>Lantana camara</em> plants and the possibility of using citric acid spray treatments to overcome the effects of nickel pollution. Transplants of <em>Lantana camara</em> were planted individually in plastic pots (20 cm diameter) filled with 5 kg of sandy soil. The nickel polluted irrigation water treatments were 0, 100, 200 and 300 mg/l. The plants were monthly sprayed with citric acid at concentrations of 0, 250 and 500 mg/l. The results showed that for vegetative growth parameters there were non significant differences in the interaction between nickel concentrations and foliar spray with citric acid, while significant reduction was observed in all parameters after irrigation with nickel polluted water and significant increase in vegetative growth parameters were observed after 500 mg/l citric acid application. For total chlorophyll and carbohydrate content, the highest significant values were obtained in plants irrigated with tap water and sprayed with 250 mg/l citric acid while the highest significant level of nickel content in the leaves, stem and roots was obtained due treatment by 300 mg/l nickel without application of citric acid.Scientific Society for Flowers and Ornamental PlantsScientific Journal of Flowers and Ornamental Plants2356-78647220200601RESPONSE OF LANTANA CAMARA PLANTS TO FOLIAR APPLIED CITRIC ACID FOR DECREASING THE HARMFUL EFFECT OF HEAVY METALS POLLUTION IN THE IRRIGATION WATER (C) EFFECT OF LEAD931079620910.21608/sjfop.2020.96209ENN.El-ShanhoreyBotanical Gardens Research Department, Horticultural Research Institute, ARC, Alexandria, EgyptO.

The aim of this study was to evaluate the effects of irrigation water contaminated with lead on the growth of <em>Lantana camara</em> plants and the possibility of using citric acid spray treatments to overcome the effects of lead pollution. Seedlings of <em>Lantana camara</em> were planted individually in plastic pots (20 cm diameter) filled with 5 kg of sandy soil. The lead contaminated irrigation water treatments were 0,100, 200 and 300 mg/l. The plants were also monthly sprayed by citric acid at concentrations of 0, 250 and 500 mg/l. The results showed that for vegetative growth parameters there were no significant difference in the interaction between lead concentrations in water of irrigation and foliar spray by citric acid, while significant reductions were observed in all parameters after irrigation with lead contaminated water. However, significant increases in vegetative growth parameters were observed after 500 mg/l citric acid application. For chlorophyll and carbohydrate contents, the highest significant value was obtained in plants irrigated with tap water and sprayed with 250 mg/l citric acid while the highest significant level of lead content in leaves, stem and roots was obtained due treatment by 300 mg/l lead without application of citric acid.Scientific Society for Flowers and Ornamental PlantsScientific Journal of Flowers and Ornamental Plants2356-78647220200601IMPROVING ROOTING AND GROWTH OF CONOCARPUS ERECTUS STEM CUTTINGS USING INDOLE-3-BUTYRIC ACID (IBA) AND SOME BIOSTIMULANTS1091299621310.21608/sjfop.2020.96213ENSayedAbdel-RahmanOrnamental Plants and Landscape Gardening Dept., Fac.

Agric., Assiut Univ., EgyptJournal Article20200420The current study was conducted to evaluate the effects of indole-3-butyric acid (IBA) at 100 ppm with or without biostimulants (<em>Agrobacterium rhizogenes</em>, seaweed extract and coconut water) as either a spray or drench for 3 minutes or 1 hour on rooting and growth parameters of three cutting types (tip, middle and basal) of <em>Conocarpus erectus</em> L. The data showed that the rooting percentage, root and vegetative characteristics of rooted cuttings were significantly increased by all treatments of IBA and/or biostimulants compared to the untreated cuttings. The individual treatments of seaweed extract and coconut water were more effective than IBA or <em>A</em>.<em> rhizogenes</em> alone. Seaweed extract as drench with or without IBA surpassed those of seaweed extract treatments as spray. Besides, the response of cuttings treated with coconut water for 1 hour was better than coconut water for 3 min. Tip cuttings were significantly better than the middle and basal ones, especially in relation to rootability of cuttings. Maximum rooting percentage and shoot characteristicsof plants were obtained from tip cuttings treated with IBA + coconut water for 1 hour, followed by IBA + seaweed extract as drench. The highest rooting percentage was associated with high endogenous levels of phenols, indole acetic acid (IAA) and gibberellic acid (GA) as well as the lowest abscisic acid (ABA) level in cutting tissues and the anatomical structure of rooted cuttings. So, it can be recommended treating tip cuttings of <em>C. erectus</em> with either coconut water for 1 hour or seaweed extract as drench combined with IBA for enhancing the rooting percentage, root and shoot growth parameters as well as content of endogenous root promoting substances.Scientific Society for Flowers and Ornamental PlantsScientific Journal of Flowers and Ornamental Plants2356-78647220200601SALT TOLERANCE OF OCIMUM BASILICUM CV.

Agric., Assiut Univ., EgyptJournal Article20200521To improve the salt tolerance of Genovese cultivar of sweet basil (<em>Ocimum basilicum</em> L.) plants, an experiment was conducted to evaluate the impact of certain growth substances (salicylic acid, seaweed extract, dry yeast and moringa leaf extract) on growth, volatile oil percentage and yield as well as chemical constituents under saline water irrigation stress conditions (control, 1000, 2000 and 4000 ppm NaCl). The obtained results revealed that the higher salinity levels (2000 and 4000 ppm NaCl) caused significant decreases in vegetative growth measurements of basil plants compared to control and the lowest salinity level (1000 ppm NaCl). Maximum reduction was observed at 4000 ppm NaCl which showed higher increase of the total phenolics and free proline contents. All recoded parameters were enhanced for plants grown under 1000 ppm NaCl. Seaweed extract was superior than other treatments in enhancing the plant tolerance to salinity which appeared in the significantly increasing of growth and volatile oil content of basil. Phenolics and proline contents were increased with salicylic acid treatment comparing with other ones. The best combination recommended as a result of the current study is treating basil plants with seaweed extract under low salinity level (1000 ppm) for improving the growth and volatile oil parameters.Scientific Society for Flowers and Ornamental PlantsScientific Journal of Flowers and Ornamental Plants2356-78647220200601RESPONSE OF TUBEROSE (POLIANTHES TUBEROSA L.) PLANTS TO CHITOSAN AND SEAWEED FOLIAR APPLICATION15316110063710.21608/sjfop.2020.100637ENW. M.F.Abd-El-HadyOrnamental Plants and Landscape Gardening Res. Dept., Hort. Res. Inst., ARC, Giza, EgyptJournal Article20200527Chitosan and seaweed extract are natural stimulants that are used to improve plant growth and flowering. Therefore, two pot experiments on tuberose plants were conducted during the two consecutive seasons of 2017 and 2018 at Horticulture Research Station at Mansoura, Dakahlia Governorate, Egypt. The aim of the study was to evaluate the response of tuberose plant (single flowers known as Balady variety) to different concentrations of chitosan (CHT) and seaweed extract (SWE) rates on growth, flowering, bulb production and some chemical constituents. Tuberose plant was sprayed six times per season with different concentrations and rates of natural stimulants under study i.e. T1 (control), T2 (20 ppm CHT), T3 (40 ppm CHT), T4 (60 ppm CHT), T5 (0.5 cm<sup>3</sup>/l SWE), T6 (1.0 cm<sup>3</sup>/l SWE), T7 (1.5 cm<sup>3</sup>/l SWE), T8 (20 ppm CHT + 0.5 cm<sup>3</sup>/l SWE), T9 (40 ppm CHT + 1.0 cm<sup>3</sup>/l SWE) and T10 (60 ppm CHT + 1.5 cm<sup>3</sup>/l SWE). These ten treatments were laid out in a randomized complete block design (RCBD) with three replicates. Generally, chitosan or/and seaweed extract treated tuberose showed significant increase (p<0.05) in plant growth, flowering and bulb production. Chitosan at higher concentration plus the higher rate of seaweed extract T10 (60 ppm CHT + 1.5 cm<sup>3</sup>/l SWE) increased the plant height, leaf number per plant and leaf width as well as number of florets/spike, spike length, rachis length and spike fresh weight. In confirmation of this, the same treatment (T10) resulted in higher values of bulb diameter and dry weight of bulb compared to the other treatments under study and unsprayed plants. In most cases, total nitrogen, total phosphorus and potassium percentages in the leaves and bulbs as well as total chlorophyll in the leaves were significantly increased by using T10 followed by T4 and T9 compared to the other ones under study. Moreover, natural stimulants (chitosan and seaweed extract) should be frequently applied in the farms to get the best growth and flowering of the tuberose plants.Scientific Society for Flowers and Ornamental PlantsScientific Journal of Flowers and Ornamental Plants2356-78647220200601EFFECT OF SOME SAFETY GROWTH STIMULANTS AND ZINC TREATMENTS ON GROWTH, SEEDS YIELD, CHEMICAL CONSTITUENTS, OIL PRODUCTIVITY AND FIXED OIL CONSTITUENTS OF CHIA (SALVIA HISPANICA L.)

The aim of this study was to investigate the possibility of improving growth, seeds yield, oil productivity and fixed oil constituents of chia (<em>Salvia hispanica</em> L.) plants by some safety growth stimulants treatments i.e. chitosan, ascobien, humic and glutamic acids and micronutrients zinc (Zn) i.e., control (tap water), 100 and 200 ppm, as well as their combinations. Plants were sprayed with safety growth stimulants gave the significantly highest mean values for all studied characteristics i.e., plant height, number of branches per plant, plant fresh and dry weights, seeds yield/plant, weight of 1000 seeds, chlorophyll a, b, carotenoids, N, P, K, total carbohydrates, fixed oil percentage, and fatty acids determination of chia (<em>Salvia hispanica</em> L.) plants, with superior for humic acid at 5 ml/l followed by glutamic acid at 200 ppm in the first and second seasons. Meanwhile, ascobien at 200 ppm ranked the third values in this concern. Irrespective of control plants the lowest values of these parameters were scored by chitosan at 5 g/l in the 1<sup>st</sup> and 2<sup>nd</sup> seasons. As for zinc concentration treatments, there was appositive relationship between the values of abovementioned parameters and zinc concentration, hence as the concentration of zinc increased the values of these parameters increased till reached the highest increases at the highest concentration (200 ppm) in the two seasons. Furthermore, the combination of humic acid at 5ml/l showed to be the most effective one for inducing the highest values of these parameters especially those sprayed with the highest concentration of zinc (200 ppm). Chromatography analysis of chia fixed oil revealed the identification of seven components. The main component was α-linolenic acid (37.28 to 39.72%). The major components were α-linolenic acid, linoleic acid, oleic acid and palmitic acid. It can be concluded that humic acid at 5 m/l with Zn at 200 ppm was the best treatment for improving growth, seeds yield, fixed oil productivity, chemical constituents and fixed oil components of chia (<em>Salvia hispanica</em> L.) plant.Scientific Society for Flowers and Ornamental PlantsScientific Journal of Flowers and Ornamental Plants2356-78647220200601DEVELOPING AIR LAYERING PRACTICES FOR PROPAGATION OF DRACAENA MARGINATA LAM.

assiut university0000-0002-6628-219XJournal Article20200507In an experiment laid out in completely randomized block design, eight experimental treatments representing all-possible combinations between indole-3-butyric acid potassium salt at 300 ppm (IBA), phloroglucinol at 300 ppm (PG) and seaweed extract (SWE) at 2 ml/l were evaluated for their effects on rooting of <em>Dracaena marginata </em>Lam. air layers. The research was conducted under shade house conditions of the Nursery of Ornamental Plants, Faculty of Agriculture, Assiut University, Egypt during 2018 and 2019 successive growing seasons. All treated air layers with IBA, PG and SWE each alone or in combinations recorded significant increases in rooting percentage comparing to untreated control air layers. The highest rooting percentages were found in air layers received 10 ml/air layer from PG alone or the IBA + SWE or IBA + PG + SWE without significant differences between them. Air-layers exposed to IBA alone or in combination with PG and/or SWE attained the most favorable root traits in terms of high number of roots with appropriate length and a balanced mass and volume. High carbohydrate concentrations positively correlated with rooting percentage and roots weight and volume. Studying correlations between rooting characteristics and the internal contents of root zone tissues of total carbohydrates and total phenolics exhibited that rooting percentage correlated positively with total carbohydrates percentage and negatively with total phenolics in root zone tissues. While, the relationships between the other root traits of succeeded layers and total carbohydrates and total phenolics contents in rooting zones did not attain any significant relations.
