SUMMARY:
This study was carried out at Experimental Station of Agricultural Botany Department, Faculty of Agriculture, Moshtohor, during 2003 and 2004 seasons on okra plant cv. Balady.
Seeds of okra were soaked in benzyl adenine (BA) at 50 or 100 ppm, pachlopetrazol (pp333) at 0.5 ,1.0 or 2.0 ppm and water as a control treatment.
The main target from this study aims to improve the morphological and physiological characters of okra plant and its fruit yield during winter months. The obtained results could be summarize as following: -
The treatments gave higher parameters of seeds germination, plant vegetative growth, photosynthetic pigments content, total fruit yield/ plant and nutritional status compared with the control. The best results of germination, vegetative growth , photosynthetic pigments content total fruiting/ plant and chemical composition of leaves and fruits were obtained with the application of benzyl adenine at 100 ppm followed by pachlopetrazol (pp333) at 1.0 ppm. Also ,these treatments gave the 6 pickings of early yield compared with the control.
Okra plants, benzyl adenine (BA), pachlopetrazol (pp333), cold tolerance and cold stress.
