Standardization of pollination time in tomato hybrid seed production.

摘要

To determine the effect of pollination time on tomato hybrid seed production, a study on pollination at different times (08.00, 09.00, 10.00, 11.00, 12.00, 13.00 and 14.00 h) was undertaken in Haveri District of Karnataka, India, during 2003 and 2004. The pooled analysis of two years' data indicated that pollination at 10.00, 11.00 and 12.00 h recorded higher fruit set percentage (48.7, 53.5 and 51.7), crossed fruit weight per plant (79.19, 80.95 and 72.52 g), seed weight per fruit (0.733, 0.826 and 0.698 g), number of seeds per fruit (73.8, 8.9 and 79.6), seed yield per plant (11.07, 11.86 and 11.11 g), seed recovery percentage (4.57, 4.75 and 4.52), respectively, as well as higher seed quality parameters, such as germination, field emergence, root length, shoot length and vigour index.
