| 摘 要： | 以特选山东密刺黄瓜品种为材料,研究了盐胁迫下,苯丙烯酸对黄瓜幼苗生理特性的影响及其施用的最佳时期和最适浓度。结果表明,苯丙烯酸能够相对提高盐分胁迫条件下黄瓜幼苗叶片的相对含水量和叶绿素含量,降低叶片细胞的质膜透性,缓解对细胞膜的伤害,抑制膜质过氧化产物丙二醛的积累,同时提高幼苗体内超氧化物歧化酶、过氧化物酶等细胞保护酶的活性,从而提高黄瓜对盐胁迫的适应性。两叶一心期为苯丙烯酸的最佳处理时期,50μmol.L-1苯丙烯酸为最适处理浓度。

| Abstract: | Effects of cinnamic acid on physiological characteristics of cucumber(Shandong Mici) seedlings under salt stress were studied,and ascertained the best concentration and the best time.The results showed that cinnamic acid could relatively increase the leaf relative water content and the chlorophyll content,decreased plasma membrane permeability,mitigated membrane damage,inhibited the accumulation of MDA(product of membrane lipid peroxidation),and promoted the activity of membrane protective enzymes,such as SOD and POD.Therefore,the adaptabilities of cucumber to salt stress were raised.The best treatment time of was during is the two euphylla time with 50!mol.L-1 of cinnamic acid. |
