摘要:

为了明确山东省主栽小麦品种的抗旱性,筛选出适宜旱地种植的小麦品种。本研究以‘济麦60’等8个品种为试验材料,采用20% PEG-6000模拟干旱胁迫,测定其萌发期各指标的变化。利用隶属函数法对相对胚芽鞘长、相对胚芽长、相对胚根长、相对发芽率、相对发芽势和胁迫萌发指数进行综合评价。结果表明:干旱胁迫不仅降低了小麦种子发芽率,也抑制了胚芽、胚芽鞘和胚根的生长。通过对8个品种的综合评价,得到其D值依次为:‘济麦60’>‘临麦9号’>‘烟农999’>‘山农30’>‘山农28’>‘鲁原502’>‘烟农1212’>‘济麦22’。根据D值大小,将8个主栽小麦品种分成三类:高度抗旱的品种为‘济麦60’和‘临麦9号’;中度抗旱的品种为‘烟农999’和‘山农30’,其他品种为敏感品种。‘济麦60’和‘临麦9号’推荐作为适宜山东省旱地种植的小麦品种。

Abstract:

To clarify the drought resistance of the main wheat varieties cultivated in Shandong Province and to screen out wheat varieties suitable for dryland cultivation, this study used eight varieties, such as 'Jimai 60', as test subjects. Drought stress was simulated using 20% PEG-6000, and changes in various indicators during the germination period were measured. The membership function method was employed to comprehensively evaluate the relative coleoptile length, relative plumule length, relative radicle length, relative germination rate, relative germination potential, and stress germination index. The results showed that drought stress not only reduced the germination rate of wheat seeds but also inhibited the growth of the plumule, coleoptile, and radicle. The D values of the eight varieties were ranked as follows: 'Jimai 60' > 'Linmai 9' > 'Yannong 999' > 'Shannong 30' > 'Shannong 28' > 'Luyuan 502' > 'Yannong 1212' > 'Jimai 22'. Based on the D values, the eight main wheat varieties were classified into three categories: highly drought-resistant varieties were 'Linmai 9' and 'Jimai 60' ; moderately drought-resistant varieties were 'Yannong 999' and 'Shannong 30'; other varieties were sensitive. 'Linmai 9' and 'Jimai 60' are recommended as suitable varieties for dryland cultivation in Shandong Province.
