Abstract
The harvesting time were significantly different for all traits of seedling rice including germination percentage, mean germination time (MGT), fresh weights of shoots and roots, dried of shoots and roots. Rice harvested at 20 days after anthesis had the highest germination percentage, and plant stands in term of fresh and dried weights of roots and shoots in all varieties, and they also had the lowest mean germination time. Rice Berry and Tubtim Chumphae had higher germination percentage after storage for six months than Sang Yod variety. When harvested at 20 days after anthesis, the germination percentages of Rice Berry, Tubtim Chumphae and Song Yod were 98.00, 99.00 and 67.50, respectively
