| Abstract | ||||
| Two experiments were carried out at Kaha protected cultivation site during winter seasons of 1997/1998 and 1998/1999. These experiments aimed to study the effect of different night temperature regimes (heating the greenhouse from 6pm to 6am continuously, from 6pm to 6am one hour on and one hour off, from 6pm to 12pm and from 12pm to 6am) with minimum temperature of 15°C on yield, quality and storability of snap bean cv. serbo which grown under plastic house conditions. From the results, it could be concluded that plants exposed to 15°C from 6pm to 6am one hour on and one hour off gave the highest production, high pod quality and storability (weight loss, decay percentages decreased and maintained pod quality during storage) as well as reduction of fuel cost. During storage periods, bean pods weight loss, decay and fiber percentages were increased, total chlorophyll was decreased with the prolongation of storage period, while dry matter % and TSS of bean pods increased till their peaks after 2 and 4 days, respectively, then it turned to decrease gradually till the end of storage period. | ||||
