Most of lectin in the young seedlings (7 to 35 days old) distribute in its cotyledon. The amount of root lectin in 7 days old seedling is rather higher, but there is a sharp decrease between the day 7 and day 14. The lectin in stem and leaf is low. During the first three weeks, the total amount of lectin in seedlings keeps a high level, but there is a sudden decrease between the day 21 and day 28.展开更多

Control of weed using Desmodium heterocarpum DC var. strigosum was studied. After growth for one year when its coverage get to 100%, Desmodium heterocarpum DC var. strigosum can control the weed growth.
