摘要: |
从普通念珠藻中提取分离出蛋白多糖,将蛋白多糖配制成0.5 mg/L、1 mg/L、2 mg/L、5mg/L、10 mg/L溶液,以蒸馏水为对照,进行水稻、黄豆、蕃茄、迟花2号菜心、矮脚葵扇黑叶白菜、绿豆种子的浸种发芽试验。浸种时间5h~5d;培养温度26℃~30℃;每培养皿50粒,每种浓度重复3次。随机移取相同数量的幼苗进行培养,测定茎长,观察根系生长情况。结果水稻、黄豆、番茄、迟花2号菜心、黑叶白菜、绿豆种子的发芽率分别比对照组增长23.3%、13.3%、12.3%、4.0%、4.7%、9.3%;浓度以1 mg/L~5mg/L为最佳。盆栽后2mg/L普通念珠藻蛋白质多糖喷洒过的绿豆平均茎长比对照组增长0.9cm,根系比对照组发达。 |

Abstract: |
The protein-polysaccharides were extracted from Nostoc Commune and prepared into solutions of 0.5mg/L, 1mg/L, 2mg/L, 5mg/L and 10 mg/L. Oryza sativa,Glycin max, Lycopersicon esculentum, late flowering Chinese cabbage,Brassica chinensis and Phaseolus radiatus were applied in the trial,with thrice repeats for each concentration,50 seeds in each petri dish, soaking time from 5 hours to 5 days from species to species, the distilled water as control.The culture temperature was from 26℃ to 30℃. The same number of seedlings from each species was choosed randomly for more grow. The growth of their roots and stems was observed. As compared with control, the germination rate increased by 23.3%,13.3%,12.3%,4.0%,4.7%, 9.3% for O. sativa, G. max, L. esculentum, late flowering Chinese cabbage,B. chinensis and Ph. radiatus,respectively. The favorable concentration ranged from 1 mg/L to 5 mg/L. When sprayed with 2 mg/L of protein-polysaccharides, the stem of B. chinensis elongated by 0.9 cm as compared to control. |
