Seed Germination and Development of Weedy Rice Collected from Farmers’ Field in Wang Thong District, Phitsanulok Province

Abstract

Weedy rice is the most serious weeds in rice production areas of Thailand. The objective of this study was evaluated of germination and early-stage development of weedy rice 2 populations collected from farmers’ fields in Phitsanulok and compared with KDML105 cultivated rice. Seed germination between weedy rice populations and KDML105 were compared by 5% agar gel method. Weekly plant height was assessed and compared among weedy rice populations and KDML105 with planted at 0- and 5-centimeters depth, respectively. The date of flowering and maturity were also recoded. Seed germination rate, early-stage development and plant height between weedy rice populations and KDML105 were no differentiation. In the other hand, weedy rice populations showed earlier days to flowering and days to maturity than KDML105. Therefore, the results of this study can be applied for ways to management of weedy rice in the future.
