Abstract
The present study was undertaken in an attempt to investigate the suitable means for improving the earliness of yield and quality of okra pods under the cool weather.
Two experimental trials were carried out at the Faculty of Agriculture, Ain Shams University, at Shoubra El-Kheima, Kalubia Governorate, Egypt during late winter and early Spring in 1996 and 1997 seasons.
5.1..The First Experiment:
The first experiment was performed at the laboratory to study the effect of osmoconditioning on seed germination and mean germination• rate under low temperature. Two kinds of PEG (6000 and 8000 daltons) and three soaking times (24, 48,
72 ,hours) were used to evaluate seed vigor under two different
gerfuination temperatures (15°C and 30°C). Primed seeds were examined for germination percentage and mean germination rate as compared with untreated seeds (soaked in distilled water).
The main results could be summarized as follows:
Germination percentage was significantly improved when seeds were soaked in solutions of PEG 8000 and PEG 6000 compared with soaking in water (control) under . low temperature. Whereas seeds soaked in PEG 8000 gave the fastest germination compared with PEG 6000 and distilled water, under low temperature.
The solution of PEG 8000 as a priming solution and 24 hours soaking p riod gave the maximum enhancement for germination under low temperature, in. addition to the best field emergence percentage and growth characters of seedling i.e., length, diameter and leaves number.
