摘要:

【目的】 研究电导率预测小麦穗部位种子活力的可行性,为快速预测种子活力提供理论依据。【方法】 以新疆小麦主栽品种新春44号为材料,在花后15 d(A15)、20 d(A20)、25 d(A25)、30 d(A30)、35 d(A35)、40 d(A40)和45 d(A45) 7个不同收获时间条件下,分别将穗部位均分为B1、B2、B3、B4、B5和B6 6个样本,形成宽广的种子活力水平范围,研究穗部位电导率与种子活力之间的关系。【结果】 种子电导率与苗高、苗鲜重、苗干重、发芽势、发芽率、发芽指数、活力指数和简化活力指数均达到极显著水平。回归模型的决定系数(R2)分别为0.656 8、0.811 6、0.864、0.802 7和0.803 6。【结论】 电导率测定简单易行,电导率与苗高、苗鲜重、苗干重、活力指数和简化活力指数间有良好的线性关系,用测定电导率的方法能够预测穗部位种子的活力。

Abstract:

【Objective】 To investigate the feasibility of conductivity prediction of seed vigor in wheat spike parts and to provide a theoretical basis for rapid prediction of seed vigor.【Methods】 The spike parts were all divided into six samples at 15 d (A15), 20 d (A20), 25 d (A25), 30 d (A30), 35 d (A35), 40 d (A40) and 45 d (A45) after flowering under seven different harvesting time conditions, namely, B1, B2, B3, B4, B5 and B6, respectively, using Xinjiang main cultivar Xinchun 44 wheat variety as the material. A wide range of seed vigor levels was formed to investigate the relationship between electrical conductivity and seed vigor in the spike parts. 【Results】 The results showed that seed conductivity and seedling height, seedling fresh weight, seedling dry weight, germination potential, germination percentage, germination index, vigor index and simplified vigor index reached highly significant levels. The coefficients of determination (R2) of the regression models were 0.656 8,0.811 6, 0.864, 0.802 7 and 0.803 6.【Conclusion】 Conductivity determination was simple and easy, and there were good linear relationships between conductivity and seedling height, seedling fresh weight, seedling dry weight,vigor index and simplified vigor index, respectively, so the method of conductivity determination was able to predict seed viability of the spike parts.
