基于生物量的冬小麦穗部主要形态参数模型
Biomass-Based Main Spike Morphological Parameter Model for Winter Wheat
摘要
Abstract
Spike morphological structure model is an important basis for the function and structure model in winter wheat. We carried out a field experiment in the 2013–2014 and 2014–2015 growing reasons using winter wheat varieties Jimai 22, Tainong 18, and Luyuan 502 under different nitrogen application levels. The morphological-structure models of wheat spike were built through dissecting the quantitative relationship between spike morphological-structure parameters and organ biomass, as well as the internal connections of morphological-structure parameters. These models were then validated with an independent dataset collected in the 2014–2015 growing season. Except for spike length, all the models of spike width, spike thickness, glume length, glume width, glume thickness, grain length, grain width, and grain thickness had higher accuracy. These models can be used to simulate spike structure in diverse varieties under different nitrogen application levels.关键词
