为了鉴定黄麻苗期的抗旱性,采用盆栽试验、人工控水法对10个不同品系黄麻幼苗进行干旱胁迫,测定其幼苗株高和幼苗叶片的相对电导率,叶绿素、脯氨酸、可溶性蛋白、可溶性糖、丙二醛含量等6个生理指标的变化,采用模糊隶属函数法对各个材料进行综合评价。结果表明,在干旱胁迫下,幼苗株高相对值变小,黄麻幼苗叶片的相对电导率,叶绿素、脯氨酸、可溶性蛋白、可溶性糖和丙二醛含量均表现为上升,且在一定干旱范围内,随着干旱胁迫的加重而升高。通过隶属函数法综合评价10个不同品系黄麻幼苗耐旱性,耐旱性由强到弱依次为:黄33>黄09-39>黄37>黄09-30>黄09-1>黄09-27>黄09-5>黄09-19>黄09-41>黄09-9。
In order to identify the drought resistance of jute during seedling stage, pot experiment and artificial water control were used to investigate the drought resistance of jute seedlings from 10 different strains. The relative conductivity, chlorophyll, proline, soluble protein, Soluble sugar, malondialdehyde content and other six physiological indicators of changes, the use of fuzzy membership function method of comprehensive evaluation of the various materials. The results showed that under drought stress, the relative value of seedling height became smaller, and the relative electric conductivity, chlorophyll, proline, soluble protein, soluble sugar and malondialdehyde content increased in the leaves of jute seedlings, Within, it increased with the increase of drought stress. Through the membership function method, the drought tolerance and the drought resistance of jute seedlings of 10 different strains were evaluated in order of Huang 33> Huang 09-39> Huang 37> Huang 09-30> Huang 09-1> Huang 09- 27> yellow 09-5> yellow 09-19> yellow 09-41> yellow 09-9.
