查询词典 propagules

Propagules and buds of Elodea nuttallii and Potamogeton crispus were exposed to acetic acid concentrations from 1 to 16 mmol/L for 3 or 6 days, and then they were subsequently cultured in absence of acetic acid. Results showed P. crispus was more tolerant to acetic acid than E. nuttallii. At acetic acid concentration of 1 mmol/L, E.

研究了暴露于不同浓度的乙酸溶液后伊乐藻和菹草无性繁殖体的萌发和幼芽的生长状况。1mmol/L的乙酸能显著抑制伊乐藻幼芽的生长(P.05)，但对其繁殖体的萌发无明显影响。

Nuttallii propagules germinated normally, but the buds was significantly inhibited (p.05) in growth and the recovery in the subsequent culture was slow. Exposures to 4 mmol/L or higher caused death of E. nuttallii. In contrast, at concentration of 4 mmol/L, all P. crispus buds survived with significant growth and had a good recovery in the subsequent culture; P. crispus turions were remarkably reduced in gerimination rate, but all sprouted in the subsequent culture.

在4mmol/L的乙酸影响下，菹草幼芽仍有明显的生长；菹草繁殖体的萌发受到显著抑制(p.05)，但在随后的培养中可全部萌发。4mmol/L以上的乙酸暴露3d或6d导致伊乐藻全部死亡，8mmol/L的乙酸处理6d或16mmol/L的乙酸处理3d或6d导致菹草全部死亡。
