Opis:
In this experiment, seedlings as sources for shoot tips was assembled from the coconut research institute (CRI) of Chinese Academy of tropical agricultural sciences germplasm, Wenchang, Hainan, China. The shoot tips were cultured on Y3 medium to study the impact of ten concentrations of 2, 4-D and three vitamin mixtures on survival, death and development % on in vitro culture establishment stage of coconut (Cocos nucifera L.). The obtained results revealed that all 2,4-D concentrations 4,7, 75, 100, 120 and 140 mg/L + any vitamin mixture did not give any development and high concentrations of 2, 4-D increased the death %. In any case, it can be concluded that the rate of differences in survival, death and development percentages exhibited by 2, 4-D concentrations was more pronounced than the analogous ones resulted by vitamin mixtures. At any rate, utilizing of (2, 4-D at concentration 25 mg/L+ vitamin mixture 1 or 2) exhibited the greatest values of survival percentage and reduced death percentage. Just as, increased the percentages of development in in vitro culture establishment stage of coconut (Cocos nucifera L.) through seedlings shoot tip.

Opis:
This study focused on examining the effect of vegetables extract foliar application on storage quality of the grapes grape (Vitis vinifera L. cvs. ‘Perlette’ and ‘King’s Ruby’). The vines were sprayed after fruit set twice at 15 days interval at concentrations of 0, 0.20%, 0.30% and 0.40%. Fruit were harvested and kept under cold-storage at 0.5 ±0.5°C and 90% RH for 28 days. The physicochemical properties of treated and untreated berries were analyzed at 7 days intervals during the cold storage. The results showed that the pre-harvest application of vegetable extracts reduced the weight loss and inhibited the fruit decay. Treated grape also had higher ascorbic acid contents, total phenolics, 2,2-diphenyl-1-picrylhydrazyl-radical (DPPH) scavenging activity, and higher soluble solid contents, titratable acidity, and reduced sugar:acid ratio. The concentration of 0.30% and cultivar ‘Kings Ruby’ gave the best result as compared to untreated control. In conclusion, pre-harvest vegetables extract application on berries showed higher antioxidant activities in grape berries, and maintained their post-harvest quality. These results indicated that foliar spray of vegetables extract could effectively improve the fruit quality, mainly through the reduction of phenolic content.
