Effects of tillage methods on senescence and grain filling characteristics of Tartary buckwheat

Xinghui WU, Yu ZHANG, Peiyun HE, Xiaoyan HUANG, Kaifeng HUANG


A field experiment was conducted on a yellow loam in 2017 and 2018. The study used a Tartary buckwheat (Fagopyrum tataricum L.) cultivar ‘Jinqiao 2’ to determine the effects of no-tillage, conventional tillage and deep tillage on the senescence and grain filling characteristics. The tillage methods were investigated based on the changes in buckwheat grain filling dynamics, root morphology and physiology, photosynthetic pigment content, antioxidant enzyme activity, malondialdehyde (MDA) content and yield formation. The initial growth power, maximum grain filling rate, the values of root morphological characteristics, root activity, photosynthetic pigment contents and antioxidant enzyme activities were the highest under deep tillage. The MDA content was the highest under no-tillage. The agronomic characters and yield formation indexes of Tartary buckwheat were better under deep tillage.

The results of this study showed that deep tillage promoted the grain filling of Tartary buckwheat, delayed the senescence and increased the final yield.

Key words: grain filling, early senescence, root morphology, deep tillage, yield.
