Abstract

This study was carried out to evaluate the effect of three synthetic cytokinin i.e. Benzyl amino purine (BAP) at (25,
and 50 ppm), 2-chloro-4-pyridyl-N-phenylurea (CPPU) at (10, and 20 ppm) and 6-furfuryl-aminopurin (Kinetin) at (25,
and 50ppm) on Okra (Abelmoschus esculentus L.) cv .Lady's fingers. Two field experiments were executed during the
two successive seasons of 2017 and 2018 in a private farm located at Abuo Homoss, El-Baharia Governorate, Egypt. The
obtained results of the two seasons, generally, revealed that spraying of the three types and levels of synthetic cytokinins,
significantly, increased plant height, number of leaves, number of branches and leaf area plant-1 compared to the
untreated control. Also, synthetic cytokinins significantly enhanced the yield attributes viz., fruit length, fruit diameter,
fruit weight and total yield plant-1. Moreover, spraying of synthetic cytokinins were superior and significantly increased
N%, P%, K%, protein % and total chlorophyll in the leaves. Likewise, it increased mean values of N%, P%, K%, protein
% and mucilage in fruits. Meanwhile, spraying of BAP at 50 ppm gave the highest mean values of vegetative growth
characters and chemical composition on leaves compared to other treatments. However, spraying of kinetine at 25ppm
gave the highest mean values of fruit length, fruit diameter, average fruit weight and total yield plant-1 in addition to mean
values of N%, P%, K%, protein % and mucilage in fruits compared to other treatments. On the other hand, all synthetic
cytokinins increased average number of days from planting to the first flower compared to control treatment under high
temperature conditions.
