摘要
研究不同浓度的纤维寡聚酸浸种对番茄种子萌发、幼苗生长及叶绿素含量的影响。结果表明:在0.1～0.001 mg/mL的浓度范围内,纤维寡聚酸浸种能促进番茄种子的萌发和幼苗的生长,并提高幼苗叶绿素含量,最适浓度为0.01 mg/mL;浓度低促进效果差,高浓度(1 mg/mL)对番茄种子萌发和幼苗生长有抑制作用,其中对根部生长的抑制作用最大。
The seed germination,seedlings growth and chlorophyll contents of tomato seeds socked with glucose oligosaccharide acids solutions of different concentration were tested,respectively.The results indicated that within the concentration range from 0.1 mg/mL to 0.001 mg/mlL,glucose oligosaccharide acids could improve the seed germination and seedlings growth significantly;the most optimum concentration for treatment was 0.01 mg/mL,and with the decreasing of concentration,promotion function decreased.The promotion function of 0.001 mg/mL concentration was not significantly.When concentration reached 1 mg/mL,seed germination,seedlings growth and chlorophyll contents of tomato was restrained.
