| 摘 要： | 采用凤丹不同部位浸提液处理玉米种子和幼苗,通过测定玉米种子发芽率、发芽势及幼苗的一些形态指标和生理指标,研究凤丹浸提液对玉米种子萌发和幼苗生长的影响。结果表明,凤丹不同部位浸提液对玉米种子萌发和幼苗生长有一定程度的抑制作用,抑制顺序表现为根浸提液根际土浸提液茎和叶浸提液。从化感效应指数看,在种子萌发过程中,玉米种子发芽势和发芽指数受凤丹浸提液影响显著;而在幼苗生长阶段,玉米幼苗根系活力和过氧化物酶(POD)、超氧化物歧化酶(SOD)活性对各浸提液的处理较敏感,上述指标可以作为衡量凤丹不同部位浸提液对其化感作用强度的指标。

| Abstract: | In order to elucidate the effects of aqueous extract fractions from Paeonia ostii on Zea mays seed germination and seeding growth,this paper studied germination potential,germination rate and some of seedling morphological and physiological indexes of Z.mays after treated with aqueous fractions extracted from different parts of P.ostii.The results showed that different aqueous fractions extracted from P.ostii had certain inhibitory effects on Z.mays seed germination and seeding growth.The inhibitory capability of aqueous fractions was extract from roof > extract from rhizosphere soil > extract from stem and leaf.From the response index,we can see that germination potential and germination index could be indicators of the strength of allelopathy when seed germinated.During seedling growth,the activities of peroxidase(POD)and superoxide dismutase(SOD)and the root activity were sensitive after treated with aqueous extract from P.ostii. |
