摘要: 为有效控制刺萼龙葵的蔓延,利用生物化感作用原理,采用不同质量浓度狼毒地上部分和地下部分的浸提液处理刺萼龙葵种子,并以玉米种子为对照,探讨狼毒浸提液对刺萼龙葵种子萌发及胚发育的影响。通过测定发芽率、发芽势、发芽指数以及胚根、胚轴长度等指标,计算化感效应指数和综合化感效应指数,评估狼毒浸提液的化感作用。结果表明:狼毒地下部分浸提液对刺萼龙葵种子萌发和胚发育的抑制效果明显强于地上部分浸提液;狼毒浸提液对刺萼龙葵种子的抑制作用明显大于玉米种子;随着浸提液质量浓度的增加,刺萼龙葵和玉米种子的发芽率、发芽势、发芽指数均呈下降趋势,玉米种子胚根长度和胚芽长度呈“低促高抑”趋势;在确保对玉米种子萌发影响较小的前提下,40 g/L狼毒地下部分浸提液为最适处理质量浓度,该质量浓度下刺萼龙葵种子发芽率为0.08%、综合化感效应指数为-0.78,玉米种子发芽率为63.33%、综合化感效应指数为-0.31。

Abstract: To effectively control the spread ofSolanum rostratum, this study used the principle of biological allelopathy to treat the seeds ofS. rostratumwith different concentrations of extracts from the aboveground and underground parts ofStellera chamaejasme, and corn seeds were used as the control to investigate effects ofS. chamaejasmeextracts on seed germination and embryo development ofS. rostratum. The allelopathic effect index and comprehensive allelopathic effect index were calculated by measuring germination rate, germination potential, germination index, radicle and hypocotyl length to evaluate the allelopathic effect ofS. chamaejasmeextract. The results showed that the inhibitory effect of the extract from the underground part ofS. chamaejasmeon seed germination and embryo development ofS. rostratumwas significantly stronger than that of the extract from the aboveground part. The inhibitory effect ofS. chamaejasmeextract onS. rostratumseeds was significantly greater than that of corn seeds. With the increase of extract concentration, the germination rate, germination potential and germination index ofS. rostratumand corn seeds showed downward trends, and the radicle length and germ length of corn seeds showed a trend of “low promotion and high inhibition”. While ensuring a small impact on corn seed germination, 40 g/L of underground part ofS. chamaejasmeextract was the optimal treatment mass concentration. At this mass concentration, the germination rate ofS. rostratumseeds was 0.08%, and the comprehensive allelopathic effect index was -0.78. The germination rate of corn seeds was 63.33%, and the comprehensive allelopathic effect index was -0.31.
