Root rot and wilt diseases of roselle attack either seedlings or adult plants. In this study, the isolation and identification of the pathogen associated with root rot and wilt symptoms of roselle in Assiut were studied during the seasons 2012-2014. The efficacy of essential oils from three plants i.e., sweet basil (Ocimum basilicum var. basilicum L.), marjoram (Majorana hortensis L.)and peppermint (Mentha piperita L.), at three concentrations (0.5, 1 and 2%) were tested against the most aggressive Fusarium isolate in vitro, as well as evaluation in vivo. Results showed that all tested isolates, Fusarium moniliform, F. solani and three isolates of F. oxysporum (No. 1, 2 and 3) were pathogenic to roselle plants while the highest pathogenicity was caused by F. oxysporum No. 3 followed by No. 1. In vitro, the three tested oils were found to have an inhibitory effect against the growth of the pathogenic fungus, the highest inhibition was observed at 2% of marjoram and peppermint (2.23 and 2.00 cm inhibition zone, respectively).Under open greenhouse conditions, results of seed coating with the threeessential oilsunder study suppressed infection with pathogenic F. oxysporum. Marjoram and peppermint were the most effective oils in reducing disease incidence, 0.5% concentration demonstrate the best protection of roselle seeds against F. oxysporum. Growth characteristics ie., plant height, No. branches and fruits/plant, fresh and dry weights of sepals were significantly higher at all treatments. Also, acidity and total anthocyanin increased significantly. Marjoram and peppermint oil at 0.5% and basil oil at 2% were the most effective concentrations in decreasing disease incidence in addition to increasing the quantity and quality of roselle yield.}, keywords = {roselle,pathogenicity,Fusarium,Anthocyanin,acidity}, url = {https://sjfop.journals.ekb.eg/article_5127.html}, eprint = {https://sjfop.journals.ekb.eg/article_5127_27fdf26439e94f12f85c4f7ca9c685a2.pdf} } @article { author = {Abdel-Moniem, Azza}, title = {EFFECT OF SOME GROWTH RETARDANTS ON GROWTH AND FLOWERING OF HELIANTHUS ANNUUS L.

Sunrich Orange Summer 981V) plant for achieving the hope of producing dwarf plant of good quality, suitable for using as a pot plant. Results indicated that most treatments reduced stem length of the treated plants with the superiority of 2450 ppm daminozide treatment which induced 50% reduction in such trait, compared to the control plants in the two seasons. However, stem diameter and number of internodes/stem were improved in response to all the used treatments. Internode length, stem fresh and dry weights were decreased with few exceptions, but the greatest decrease in these criteria was attained by daminozide treatment at any rate and ethephon one at 250 ppm. Number of leaves/plant were increased by the various treatments. Root length increased over control with few exceptions in both seasons. However, the highest averages in most measurements were achieved by ancymidol, especially at 20 ppm level. A significant flowering earliness in the two seasons was noticed in plants sprayed with ethephon at 250 ppm. The least number of days from flower bud appearance to opening was obtained by the 20 ppm ancymidol treatment, but the plants treated with the other treatments took longer time to anthesis. Ethephon treatments elevated the mean number of lateral buds/stem to the maximum, while ancymidol ones gave the largest flower heads. Number of ray flowers/head, disc diameter and flower head fresh and dry weights were improved due to most treatments. Content of photosynthetic pigments were slightly improved with few exceptions. Total phenols content reached the maximum by ancymidol treatments, followed by the ethephon ones. However, total indoles content was not affected by most of the used treatments. In addition, the percent of total soluble sugars was increased by ancymidol at 5 ppm, daminozide at 2450 ppm and ethephon at 500 ppm treatments, while other treatments declined it. On the other hand, the percent of N, P and K was generally decreased in response to the various treatments, with few exceptions as compared to control.  }, keywords = {Sunflower (Helianthus annuus L.),Growth retardants,dwarfing,Ancymidol,daminozide,Ethephon}, url = {https://sjfop.journals.ekb.eg/article_5128.html}, eprint = {https://sjfop.journals.ekb.eg/article_5128_858d5d9deeae8f4f242266f980637215.pdf} } @article { author = {Abdel-Moniem, Azza}, title = {EFFECT OF SOME GROWTH RETARDANTS ON GROWTH AND FLOWERING OF HELIANTHUS ANNUUS L.

Sunrich Orange Summer 981V) plant for achieving the hope of producing dwarf plant of good quality. The objective of this investigation was to detect the response of sunflower plants to tank mix ratios and application methods of ancymidol, daminozide and ethephon for production of a dwarfed and picturesque specimen in an appropriate size. The results indicated that all the used combinations significantly decreased stem length of the treated plants. The shortest stems and internodes were obtained by ancymidol at either 5 or 20 ppm (seed soaking) + 500 ppm ethephon (spray). Stem diameter was increased by all combinations to reach the maximum by 5 ppm ancymidol (spray) + 500 ppm ethephon (spray). The number of internode/stem was not greatly affected by the used combinations. However, the number of leaves/plant was significantly increased by all treatments. Also, all combinations caused a marked increment in the root length, with the superiority of 20 ppm ancymidol (seed soaking) + 2450 ppm daminozide (spray), which scored the longest roots in the two seasons. Spraying plants with 5 ppm ancymidol + 250 ppm ethephon or 20 ppm ancymidol + 500 ppm ethephons induced the greatest precocity in flower bud appearance and opening. Seed soaking in 20 ppm ancymidol solution and spraying with 1250 ppm daminozide reduced number of days from flower bud appearance to its opening . The mean number of lateral buds/stem, number of ray flowers/head and disc diameter were significantly improved, with few exceptions due to the different combinations than control plants in both seasons. Data, revealed that the highest content of chlorophyll a, b, carotenoids and total phenols were scored by spraying with either 5 or 20 ppm ancymidol + 500 ppm ethephon solutions. Total indoles and total soluble sugars were inconsistent and the percent of N was generally decreased. As for P%, it increased by most combinations, but K% increased only by combining between ancymidol + ethephon.  }, keywords = {Sunflowers,Ancymidol,daminozide,Ethephon,foliar spray}, url = {https://sjfop.journals.ekb.eg/article_5129.html}, eprint = {https://sjfop.journals.ekb.eg/article_5129_80aa0ba39857023990094121c9eeeff4.pdf} } @article { author = {Ibrahem, Hanan}, title = {EFFECT OF IRRIGATION WATER SALINITY LEVELS AND DIFFERENT ORGANIC MANURES COMBINED WITH BIO-FERTILIZERS ON GROWTH OF CONOCARPUS ERECTUS L.

The N, P and K percentages in the leaves were increased with decreasing irrigation water salinity and organic manures, while the Na+, Cl- and proline concentration in the leaves increased with increasing irrigation water salinity and organic manures.
