摘  要:
以盐棉48号、苏玉1号劣变种子为材料,观察到种子吸胀及萌发时适当处理的氯化胆碱(CC)使其萌发率分别从对照的29.2%、39.1%提高到64.5%、50.6%。200mg/LCC浸48h使苏玉1号劣变种子萌发时减少电解质及紫外吸收物质外渗。认为cc能够维护膜系统的完整性,从而能部分恢复劣变种子的生活力。

摘  要:
It has been observed that percentages of germination of deteriorated corn grains (CV, Suyu No.1) and cotton seeds (CV, Yanmian No. 48) could be greatly increased by choline chloride (CC) at 200mg/L and for incubation of 48h or 6h respectively, that isrespectively from 29. 2%or 39. 1 % of check control to 64. 5% or 50. 6% after application of CC. Treatment with 200 mg/L of CCcould reduce electrolytes and UV-absorbent substances leaked from germinating corn grains. It is suggested that CC could maintain integrity of membrane system of seeds so that it could partly recover viability of deterirated seeds.
