核桃%水浸液%黄芩%化感效应
覈桃%水浸液%黃芩%化感效應
핵도%수침액%황금%화감효응
以不同产地的黄芩(Scutellaria baicalensis Georgi)种子为材料,研究了不同浓度(0,0.005,0.01,0.02,0.03和0.04 g·mL-1)核桃(Juglans regia L.)叶水浸液对黄芩种子萌发和幼苗生长的影响.结果表明:低浓度(0.005,0.01,0.02 g·mL-1)的核桃叶浸提液对不同产地黄芩种子的萌发有明显的化感促进作用；随着水浸液浓度的升高,其对受体的促进作用逐渐减弱、消失,甚至表现为抑制作用.在试验浓度范围内,核桃叶水浸液对黄芩种子的幼苗根长、苗高、相对电导率、可溶性糖含量及可溶性蛋白含量均表现为促进作用,最佳作用浓度为0.02g· mL-1.核桃叶水浸液可以在某种程度上促进黄芩种子的萌发和幼苗的生长.
