온도 및 일장처리가 쓴메밀(Fagopyrum tataricum)의 생육에 미치는 영향

Abstract

This study was carried out to investigate the effects of temperature and photoperiod onthe growth of Fagopyrum tataricum. It showed a tendency to promote the germination rateand plant height of tartary buckwheat under high temperature. Plant height and number ofleaves were promoted in the order of 25>20>15>30℃ under the different temperature after30 days of the planting. In the 10, 12, 14hr photoperiods at 20℃, plant height, number ofleaves and dry weight were increased as much as photoperiod became long except by 16hr.Rutin contents was not regular both common and tartary buckwheat under thephotoperiods. The rutin content in leaves was higher than stem. Compared to yield oftartary and common buckwheat, plant height, number of leaves, number of branch andstem diameter of tartary buckwheat increased more than common buckwheat. Especially,number of leaves was increased about 2.5 times more than common buckwheat. And therewas a difference in about 2.1 times in grain weight and about 5.4 times in number of grains.Rutin content was 1469.8mg/100g in grain of tartary buckwheat. It was about 60 timeshigher than 22mg/100g in grain of common buckwheat.
