摘要/Abstract

摘要：

【目的】研究不同灌溉条件下一个春小麦重组自交系(RIL)冠层温度与产量性状的相关性,为抗旱高产春小麦品种选育和栽培提供参考。【方法】于2014~2016年,对春小麦重组自交系(RIL)群体的188个株系,在充分灌溉和有限灌溉条件下, 分析RIL群体的抽穗期、灌浆初期和灌浆中期的冠层温度与产量的关系。【结果】有限灌溉条件下,春小麦各个生育时期的冠层温度均极显著高于充分灌溉(P<0.01)。在同一灌溉条件下,不同生育期之间的冠层温度也存在极显著差异(P<0.01),且随着生育期的推进,冠层温度呈升高趋势。产量及大部分产量构成因素与各生育时期的冠层温度之间均呈负相关性。冠层温度和产量及其构成因素之间的负相关性由强到弱依次为产量、千粒重、穗粒数、单株粒重。在有限灌溉条件下,产量与各个时期的冠层温度具有明显的线性递减关系,且与灌浆中期的冠层温度具有最明显的线性关系,而在充分灌溉条件下,这种线性递减关系不明显。【结论】有限灌溉条件下,春小麦产量及产量构成因子与冠层温度具有明显负相关性,冠层温度可作为一个重要指标用于指导春小麦育种、栽培等生产实践。

Abstract:

【Objective】 The present study focuses on the relationship between canopy temperature (CT) of spring wheat and its yield in order to provide some references for the breeding and cultivation of drought resistance and high yield spring wheat. 【Methods】 188 recombinant inbred lines (RILs) were grown in the experiment stations in Changji prefecture, Xinjiang, under full and deficit irrigation conditions from 2014 to 2016 growing seasons. The CT of heading stage, early filling stage and middle filling stage were measured by infrared thermometer. 【Results】 The variations of CT in different stages and the relationship between CT and yield were analyzed. The results showed that CT of spring wheat was significantly higher (P<0.01) under deficit irrigation than that under sufficient irrigation in every growing stage. CT also differed significantly (P<0.01) among different growing periods and CT rose with the development of growing stage under both irrigation conditions. The most negative correlation was in yield, followed by thousand seed weight, spikelet number and kernels per spike. Under deficit irrigation, the yield had obvious linear decreasing relation with CT in each period, and displayed the most obvious linear relation with CT in the middle of filling stage, but under sufficient irrigation, the linear decreasing relation was not obvious.【Conclusion】 Overall, yield and yield component factors of spring wheat were closed related to CT under sufficient irrigation. CT can be used as an important indicator for the breeding and cultivation of spring wheat.
