Abstract:

Objective】To clarify the impact of Sophora alopecuroides L. extracts on allelopathy of Hami melon seed germination by investigating the interactive effects of soil extracts (continuous cropping for 2 years and 7 years) and different concentrations of Sophora alopecuroides L. (5, 25 and 50 g/L) on the seed germination of Hami melon.【Methods】The germination potential, germination rate, germination index, and allelopathy response index of the Hami melon seeds were determined using the filter paper method in Petri dishes.【Results】The continuous cropping soil extracts significantly inhibited the seed germination rate, with a decrement in germination rate of 30.56% and 41.67% respectively. Similarly, Hami melon seed germination rate decreased by 19.44%-61.11% after treatment of Sophora alopecuroides L. water extracts. However, further findings from the interaction effects of continuous cropping soil extracts and Sophora alopecuroides L. extracts on seed germination indicated that low concentration of Sophora alopecuroides L. extracts (5g/L) could clearly reduce the long-term continuous cropping barrier effect of Hami melon (7 years) compared to 2 years. 【Conclusion】Low concentration of Sophora alopecuroides L. (5 g/L) might mitigate the seed germination allelopathy caused by long-term continuous cropping of Hami melon.

Key words: allelopathy; continuous cropping obstacle; seed germination; Hami melon; Sophora alopecuroides L.

摘要:

目的】研究苦豆子浸提液对哈密瓜种子萌发化感效应的影响。【方法】分析比较2年、7年哈密瓜连作年限土壤浸提液以及不同浓度苦豆子浸提液(5、25和50 g/L)对哈密瓜种子萌发的交互影响。通过培养皿滤纸法,统计种子发芽势、发芽率、发芽指数以及化感效应指数。【结果】连作土壤浸提液可显著抑制哈密瓜种子的萌发,其种子发芽率分别降低了30.56%,41.67%。在不同浓度苦豆子浸提液处理下,哈密瓜种子发芽率降低了19.44%~61.11%。在土壤浸提液与苦豆子浸提液的交互试验中,苦豆子浸提液加剧了2年哈密瓜连作土壤浸提液的种子萌发抑制效应;但5 g/L的苦豆子浸提液却可以显著消减7年哈密瓜连作土壤浸提液的种子萌发抑制效应。【结论】低浓度的苦豆子浸提液(5 g/L)可以消减哈密瓜长期连作带来的种子萌发化感效应。
