摘要：研究了南方红豆杉种子的种皮和胚乳(含胚)的不同浓度甲醇浸提液对油菜种子萌发和幼苗生长的影响。研究结果发现:种皮和胚乳不同浓度的提取液对油菜种子的萌发、幼苗的生长均存在一定的抑制作用。随着浸提液浓度的升高,油菜种子萌发率、幼苗的根长和茎长均逐渐下降。在相同的浓度中,油菜种子在胚乳浸提液中的萌发率比种皮浸提液低,油菜幼苗的根长在种皮浸提液中比胚乳浸提液中短。方差分析结果表明,不同处理组之间幼苗的根长存在显著的差异。结果表明红豆杉种皮和胚乳均有抑制物质存在,胚乳浸提液对油菜种子的萌发抑制作用较强,而种皮浸提液对油菜根长抑制作用强。
Seeds germination and seedlings growth ofBrassica campestris in different concentrations of the methanol extracts from the seed coat and endosperm （including embryo） ofTaxus chinensis var.mairei were studied in this paper. The results showed that there existed inhibition of seed coat and endosperm extracts of different concentrations on the seed germination and seedlings growth ofB.campestris in a certain extent. With the extract concentration increased,B.campestris seed germination rate, seedlings root length and stem length were gradually decreased. Germination rate ofB.campestris in seed endosperm extracts was lower than that in the seed coat extracts in the same concentrations, and seedlings root length in the seed coat extracts was shorter than that in the endosperm extracts. Analysis of variance results showed that significant differences was existed among different treatment groups for root length of seedlings. The research results indicated that inhibiting substances were existed both in the seed coats and endosperm forT. chinensis var. mairei seeds, and endosperm extracts strongly inhibited seed germination ofB. campestris , while the seed coat extracts strongly inhibited root length ofB. campestris .
