speed of germination, days to emergence, mean germination time, germination enhancement, seed qualityAbstract
Buckwheat seed is often found the problems with low germination, delayed germination and non-uniformity in the field. Thus, the objective of this research was to study the effects of temperature and soaking duration during hydropriming on germination and vigor of buckwheat seeds in order to enhance seed germination. Seeds were soaked in reverse osmosis (RO) water at different temperatures and soaking durations and seeds were then decreased moisture content until 8% at Seed Technology Laboratory, Department of Horticulture, Faculty of Agriculture, Kasetsart University during September to October, 2017. The experiment was designed in 2×3 factorial in completely randomized design with non-primed seeds (control). Factor A was the temperature at 20°C and 30°C. Factor B was soaking duration for 6, 12 and 18 hrs. The results showed that hydroprimed seeds at 30°C for 18 hrs had high germination (90.50%), speed of days to emergence (1.33 days) and speed of mean germination time (4.50 days) when compared with non-primed seeds (82.50%, 1.48 days and 5.04 days, respectively). It is useful for growing buckwheat seeds in the field in order to enhance germination and rapid seedling growth with weed competition.
