摘要:
大田作物群体根系的生理生态过程及其塑性反应必然决定根系构型特定的3D拓扑性状。为了解析大田作物地下部的生理生态过程,需要探究一种能够保留原位拓扑结构的群体根系构型测试与模型化方法,以及基于根系构型模型的表型参数设计方法。本研究以宁麦13为试验材料,利用1.5 cm等株距免耕精密播种法获取相对准确的行株距和一致的群体,在完成小麦根系构型的数字化基础上,使用Pro-E软件构建群体根系构型的3D拓扑模型,并进一步设计可供定量解析根系系塑性性状的根系构型拓扑表型参数,以侧位根长比作为根系构型拓扑表型的专用指标,使用该指标分别对小麦的幼苗期、分蘖期、拔节期进行等株距条播群体的个体植株根系构型拓扑表型的定量分析。结果表明,根系构型3D拓扑的Pro-E模型及本研究构建的表型指标能够初步捕捉到邻株根系构型规避现象,且该现象在小麦的不同生育期有所差异。在大田环境下本研究所探讨和设计的小麦根系构型的拓扑表型参数及其配套的大田群体精准控制、根系构型数据化、模型化及模型的拓扑表型参数化技术有利于捕捉大田环境群体条件下的个体小麦地下部生理生态过程。
Abstract:
The physiological and ecological processes and related plastic reactions determinate the 3D topological traits of crop root system architecture (RSA). To analyze the physiological and ecological processes in the anderground part of field crops, it is necessary to explore a method for measuring, parameterizing and modelling the 3D topologies of crop RSA and the design of phenotypic parameters based on RSA model. In this study, Ningmai13 was used and drilled in row with precise manner, and the plant-to-plant distance was 1.5 cm. Based on the digitization of wheat root system architecture the 3D topological model of population root architecture was constructed by Pro-E software. Furthermore, the topological phenotypic parameters of root architecture were designed for quantitative analysis of plasticity. The side root length ratio (SRLR) was used as a special index, and the quantitative analysis on topological phenotype of root architecture was carried out at seedling stage, tillering stage and jointing stage of wheat. Results showed that Pro-E model and phenotypic indices constructed in this study could initially capture the avoidance phenomenon, and the phenomenon was different at different growth stages. In the field, topological parameters of wheat root architecture and the corresponding techniques are helpful to capture the physiological and ecological processes of individual wheat.
