Abstract
With different garlic stalks aqueous extracts as materials,and with tomatoes,peppers,cucumbers,lettuce,onions and welsh onions as receptor material,different receptors vegetable germination'germ length and fresh weight,radicle length and fresh weight were studied by using different concentrations of aqueous extracts of garlic stalks.Afterward,allelochemicals of garlic stalks aqueous extracts were separated by thin layer chromatography test,and their biological activity on lettuce and then identified inhibitory substances were studied,in order to provide the theoretical basis for effectively using allelopathy of garlic stalks.The results showed that all concentration designed in this test restrained the germination rates of tomato and pepper,but had no obvious effect on cucumber'germination rate;the influence of garlic straw aqueous extracts on the germination(embryo and radicle)of tomato,pepper and cucumber was dual concentration effect:the high concentration inhibited but the low concentrations displayed promoter action;garlic straw aqueous extracts had inhibition on the germination of onion and welsh onion.Five spots were observed on TLC plates under UV light,of these,spot 2,spot 3and spot 5suppressed lettuce emergence.The second spot contained diethyl phthalate and a derivative of phenol,biphenyl and 1-methyl-naphthalene were detected in the third spot.In the fifth spot,aromatic compounds and aliphatic ester were identified.
