Abstract
A field experiment was conducted to assess the response of cucumber (commercial F1 hybrid Hayel) grown on two different planting dates (April 15 and May 20) to exogenous application of salicylic acid (SA) seed pretreatment. The experiment was implemented in the farm of the Faculty of Agriculture, Al-Azhar University in Assiut City, during two successive summer seasons (2014 and 2015). The pretreatments comprised overnight (20 - 24 h) seed imbibition in SA solution at concentration of 0.07 mM, 0.18 mM and 0.29 mM. Seed imbibition in distilled water served as control treatment. Planting date did not affect almost all major fruit yield-related traits. This included chlorophyll a contents in the leaf tissues, number of female flowers per cucumber plant, the plant stem diameter and the leaf number per plant. Therefore, influence of planting date on fruit yield was inconsistent in the 2-year trial. On the other hand, SA treatment exhibited consistent main effect. Among the studied SA concentrations, 0.07 mM, 0.18 mM elevated the total chlorophyll and both chlorophyll a and chlorophyll b contents in the leaf tissues. Also, these SA concentrations increased the number of female flowers per cucumber plant, the plant stem diameter and the leaf number per plant. Total fruit yield, in particular, was the highest when seeds were pretreated with 0.18 mM SA. The increase in total fruit yield was, on average, 38.2% as compared to the control treatment. Pre-sowing seed treatment with 0.29 mM SA did not affect the fruit yield.
