The objective of this study was to evaluate the use of night break to prolong marketing period of the plant. Two factors were included, the first factor was night break (NB) at five levels (natural day, 5 seconds (flash light), 30, 60 and 120 minutes) starting at 10:00 p.m. for one month. The second one was spraying paclobutrazol at three levels (0, 500, 1000 mg l-1). The experiment was designed as split plot design, night break was set in the main plot. The results showed that NB had significant effect on values of vegetative growth characteristics. It also delayed the date of initiation and opening of the inflorescences. The treatment of 120 minutes had highest number of days to initiation and opening of flower (167.73 and 183.55 days, respectively), while natural day treatment gave lower number (133.25 and 165.73 days, respectively). The treatment of paclobutrazol at 1000 mg l-1 concentration gave lowest plant height: pot ratio and highest plant diameter (1.25 and 56.60 cm, respectively). Highest shelf life was 45.10 days at the treatment of interaction between night break of 120 minutes and spraying with paclobutrazol at 1000 mg l-1.}, keywords = {Dendranthema grandiflora,night break,Paclobutrazol,pot plant}, url = {https://sjfop.journals.ekb.eg/article_91392.html}, eprint = {https://sjfop.journals.ekb.eg/article_91392_96e173c98935ede8254ef37e0edb635b.pdf} } @article { author = {El-Naggar, Ali and El-Kiey, T. and Koreish, E. and Zaid, N.}, title = {PHYSIOLOGICAL RESPONSE OF GAZANIA PLANTS TO GROWING MEDIA AND ORGANIC COMPOST}, journal = {Scientific Journal of Flowers and Ornamental Plants}, volume = {7}, number = {1}, pages = {11-26}, year = {2020}, publisher = {Scientific Society for Flowers and Ornamental Plants}, issn = {2356-7864}, eissn = {2536-9296}, doi = {10.21608/sjfop.2020.91393}, abstract = {This work was carried out during two successive seasons of 2017 and 2018 at the Nursery, Department of Floriculture, Ornamental Horticulture and Landscape Gardening, Faculty of Agriculture, Alexandria University, Egypt to investigate the effect of different growing media (calcareous + sand + peat moss at the rate 70 and 40%) and two types of organic compost (rice straw and sugar beet at 30 and 60%) and their interaction on the growth and flowering of Gazania splendens plants. The experimental design in split-plot arrangement, with four replications, in both seasons. The growing media were laid out in the main plots and sub-plots included the different organic composts. Three pots were used as a plot for each treatment. The means of the individual factors and their interactions were compared by L.S.D. test at 5% level of probability. The obtained results can be summarized as follows;  most vegetative growth characteristics such as: number of tillers (54.74), number of leaves (239.76) and leaves fresh weight (100.29 g) were significantly affected by organic compost at 60% sugar beet with peat moss treatment, flowers characteristics (inflorescences diameter (9.34 cm) and number of inflorescences (14.87), and inflorescences dry weights (0.459 g), responded significantly to the interaction between the different media and organic compost, the highest significant values were obtained by organic compost at 30 and/ or 60% sugar beet and peat moss. Total chlorophyll (56.23 mg/g f.w.), nitrogen (3.42%), phosphorus (0.74%) in the leaves were the highest with 60% sugar beet and 40% peat moss in both seasons. However, potassium (2.85%) in the leaves gave the highest significant values by 60% sugar beet with calcareous soil (40%) for both seasons. It can be recommended that producing high quality of Gazania splendens plants for different decorative purposes in landscaping can be accomplished by growing plants in the mixture of peat moss (40%) with organic compost at rate 60% sugar beet led to improve its characteristics.}, keywords = {Gazania,growing media,Organic compost,Soil amendments,Sugar beet,rice straw,perennial plants,Asteraceae}, url = {https://sjfop.journals.ekb.eg/article_91393.html}, eprint = {https://sjfop.journals.ekb.eg/article_91393_7d6cda43a4a528bf1767e09e3bd6b88a.pdf} } @article { author = {El-Naggar, Ali and Hassan, M. and Saeid, A.}, title = {GROWTH AND ESSENTIAL OIL ANALYSIS OF OCIMUM BASILICUM, L.

The aim of the present investigation was to evaluate the effect of seaweed extract and active dry yeast on vegetative growth and oil yield of Ocimum basilicum L. The layout of the experiment of both seasons was split-plot design in three replicates. Each replicate contained 20 different treatments (4 levels of dry yeast x 5 levels of seaweed) five plants were used as a plot for each treatment. The main plot represented the active dry yeast at the concentrations of 0,2,4 and 6 g/l which sprayed on plant leaves. The sub-plot was seaweed extract at the concentrations of 0, 1, 2, 3 and 4 g/l added as a foliar application. The most of vegetative growth and yield traits responded significantly to the combination of active dry yeast with seaweed extract as biofertilizer on basil plants. Plant height, number of leaves, leaves dry weights and leaf area were significantly affected with spraying plants by dry yeast and seaweed. As a general, the treatment namely 6 g/l + 4 g/l gave the best combination between the dry yeast and seaweed.  The best oil percentage was recorded by using 4 g/l dry yeast with 4 g/l seaweed in the first cuts of both seasons and by using 6 g/l dry yeast with 4 g/l seaweed in the second cuts in both seasons. The major components of sweet basil essential oil were linalool, giving the highest percentage (52.16-79.55%) by using 6 g/l dry yeast with control (0 g/l) seaweed. Estragole, recorded the highest percentage (5.14-11.79%) by using 6 g/l dry yeast with 1 g/l seaweed. Eucalyptol, gave the highest percentage (1.54-9.72%) by using 4 g/l dry yeast with 2 g/l seaweed. Methyl cinnamate, the highest percentage (1.12-10.37%) was produced by using 0 g/l dry yeast with 4 g/l seaweed. Tau-cadinol, the highest percentage (1.01-6.97%) was obtained by using 2 g/l dry yeast with 2 g/l seaweed. Trans-α-bergamotene, the highest percentage (1.23-5.18%) was resulted by using 0 g/l dry yeast with 0 g/l seaweed. Bornyl acetate, gave the highest percentage (1.12-4.53%) was obtained by using 2 g/l dry yeast with 4 g/l seaweed. Form this study we recommend economically and environmentally to fertilize sweet basil by spray bio fertilization as dry yeast at the rate 4 or 6 g/l with spray the plants by seaweed at the rate 4 g/l to obtain the best growth, oil yield, and safe for human being chemical composition of Ocimum basilicum L.}, keywords = {medicinal and aromatic plants,Ocimum basilicum,L,seaweed extract,essential oil,dry yeast,basil}, url = {https://sjfop.journals.ekb.eg/article_91394.html}, eprint = {https://sjfop.journals.ekb.eg/article_91394_c8a20b536039cabf676f6c92377fd4fd.pdf} } @article { author = {Saadawy, F. and El- Fouly, A. and Sayed, A.}, title = {EFFECT OF SOME HORMONAL TREATMENTS ON GROWTH AND CHEMICAL COMPOSITION OF RHAPHIOLEPIS UMBELLATA SHRUB}, journal = {Scientific Journal of Flowers and Ornamental Plants}, volume = {7}, number = {1}, pages = {45-52}, year = {2020}, publisher = {Scientific Society for Flowers and Ornamental Plants}, issn = {2356-7864}, eissn = {2536-9296}, doi = {10.21608/sjfop.2020.91396}, abstract = {A pot experiment was consummated on Rhaphiolepis umbellata seedlings grown under seran greenhouse at Al-Zohriya Garden, Hort. Res. Inst., ARC, Giza, Egypt during the two consecutive seasons 2017 and 2018, to study effects of five foliar spray treatments of a mixture containing three growth regulators (PGR), at the same concentration for each, on plant growth and chemical composition. The three-tested PGR were NAA, GA3 and BA, while the five concentrations for each were 0 (control treatment), 100, 200, 300 and 400 ppm. Obtained results indicated that, generally, all recorded vegetative and root growth traits; i.e., plant height, stem diameter, numbers of branches and number of leaves/plant, leaf area, root length and number of roots/plant increased significantly under the effect of all tested PGR treatments, compared to the control plants. The highest increases in this regard were recorded in plants sprayed with PGR at 200 ppm, while the least values were found in the untreated control plants, followed by plants sprayed with the highest PGR concentration of 400 ppm for the two seasons. The same trend was noticed in respect of leaf chemical constituents, as plants that recorded the highest vegetative and root growth (treated 200 ppm PGR) also contained the highest values of total chlorophyll and carotenoids (mg/g f.w.) as well as percentages oftotal carbohydrate, N, P and K in leaf tissues. Accordingly, it could be recommended to apply the mixture of these three growth regulators 200 ppm on seedlings of Rhaphiolepis umbellata, two times monthly during the growing season to get the best plant growth and quality.}, keywords = {Rhaphiolepis umbellata,foliar spraying,Plant growth regulators,NAA,GA3,BA}, url = {https://sjfop.journals.ekb.eg/article_91396.html}, eprint = {https://sjfop.journals.ekb.eg/article_91396_2d19daee41348465c2d927ab51c75af4.pdf} } @article { author = {Abo El-Fadl, Shams and Osman, A. and Al-Zohairy, A. and Dahab, Abeer and Abo El Kheir, Zakia}, title = {ASSESSMENT OF TOTAL PHENOLIC, FLAVONOID CONTENT, ANTIOXIDANT POTENTIAL AND HPLC PROFILE OF THREE MORINGA SPECIES LEAF EXTRACTS}, journal = {Scientific Journal of Flowers and Ornamental Plants}, volume = {7}, number = {1}, pages = {53-70}, year = {2020}, publisher = {Scientific Society for Flowers and Ornamental Plants}, issn = {2356-7864}, eissn = {2536-9296}, doi = {10.21608/sjfop.2020.91397}, abstract = {In the current investigation, three selected Moringa species (M. stenopetala, M. peregrina and M. oleifera) grown at Orman Botanical Garden, Giza, Egypt were tested to quantify spectrometrically, the total phenolic compounds according to Folin–Ciocalteu's assay and flavonoids content to assess their corresponding effect on their antioxidative activity. Different leaf extracts (hexane, ethyl acetate and ethanol 70%) of the three studied species were prepared. The obtained results revealed that M. peregrina gave the best extract yield for the leaves extracted by the different solvents. Regarding the total phenolic compounds, data exposed ethanol 70% extract of M. peregrina leaves as the highest value among other species (11.66 g GAE/100 g extract), while it was for hexane extract that showed the highest value among other species in flavonoids content (7.21 g QE/100 g extract). Antioxidant activity of leaf extracts was evaluated by means of 2,2-dyphenyl-1-picrylhydrazyl (DPPH) and 2,2-azino-bis (3-ethylbenzthiazoline-6-sulphonic acid (ABTS) scavenging assays. Data exhibited M. peregrina as the highest species to afford free radical scavenging activity with DPPH and ABTS assays in all concentrations of all extracts especially, 1000 μg/ml of ethanol (70%) with 97.00 and 92.67% inhibition, respectively. Moreover, HPLC with UV detection was employed for the identification and quantification of the phenolic compounds and flavonoid content, present in leaf methanolic extracts of the studied species. HPLC assay identified 25 phenolic compounds and 11 flavonoids in the leaves. It was noticed that M. stenopetala leaves emerged the highest values in most of the phenolic compounds and flavonoids. Eventually, it can be concluded that Moringa leaves showed their certain nutritional value and therefore had the potential as source of natural antioxidants.

This study was conducted to investigate the effect of irrigation with saline water (8000 and 16000 ppm) on some trees and their effect on transpiration rates, and the impact of these trees on reducing the atmospheric temperature and therefore their impact on climate change. The trees under study were used in the study: Bauhinia variegata, Cassia fistula, Cassia nodosa, Eucalyptus camaldulensis, Ficus retusa and Khaya senegalensis. In general, results indicated that, the atmosphere was cooler around Cassia fistula by reduction of atmospheric temperature by 6.5 °C (also, it produces odorous flowers) followed by Eucalyptus camaldulensis (5.3 °C). Reduction of temperature was correlated with high transpiration rate after irrigation with saline water after 2, 4 and 8 days of irrigation. It can be concluded that, using of saline water in irrigation of ornamental trees is efficient to induce the cooling effect in our gardens.
