Abstract
The effect of foliar spray with cycocel, Salicylic acid, and Silicon on cucumber vegetal characteristics, grown under salinity stress and green house conditions, was studied, at research center of Al- Hennadi, related to Agriculture research center – Lattakia- Syria. The research concluded 14 treatments: 1-C , 2- SA 25, 3- SA50 , 4- CCC400 , 5-CCC600, 6-Si 100 , 7- Si 200, 8-S, 9 –S+SA25 , 10- S+SA50, 11-S+ CCC400 , 12- S+ CCC600, 13- S+ Si 100, 14- S+ Si 200. The results showed that foliar spray with Si,CCC and SA, enhanced inter number of male and female flowers, sexual ratio of flowering, contract ratio, average number and weight fruits, early and total production when plants were irrigated with normal or saline water. The results showed as well that Si200 treatment significantly excelled in all fruiting characteristics and gave the highest amount of total production. The results indicated that SA, CCC, and Si could alleviate the harmful effect of salinity, with preference of Si which was more effective.
Key words: Salinity – Silicon – Salicylic acid – Cycocel- Cucumber- Green House.
