Morphologic Variability in Buckwheat (Fagopyrum esculentum Moench)

Abstract

Maturity in buckwheat begins successively from bottom stems to up and the flowers, green and mature grains are present on the plants in harvest period. Therefore, there isn‘t homogeny a ripening, and yield decreases. This study was conducted to investigate effect of plant morphology (main stem-branch, middle-branches and sub-branches) on change of the yield and its mineral nutrient contents in buckwheat. The field experiments were arranged according to a randomized complete block design with three replications in the 2014 and 2015 years in Isparta ecological conditions and using Aktaş buckwheat cultivar. The grain yield in main stem-branch, middle-branches and sub-branches and contribution at yield of these of buckwheat were statistically significant in the both years. According to plant morphology, the highest grain yield in per plant 1.548 and 1.579 g/plant, respectively, and the highest contribution to per plant yield 40.72% and 38.61%, respectively, were determined in sub-branches. The lowest values were obtained from main stem-branch. It could be advised that the optimal harvest time full matured (brown seeds) of the seeds on the lower and middle lateral branches the highest contributed on yield in buckwheat. The mineral nutrition contents varied according to plant morphology, and the highest values, except for K and Mn, were determined in the main stem-branch.
