摘要
用不同浓度PEG（6，000）在15℃下预处理苎麻种子，能促进种子萌发，提高种子活力和呼吸速率，其最适处理浓度和时何分别为20％和24h。此外用20％PEG须处理苎麻种子24h进行盆栽试验，促进幼苗生长发育，增加抗病能力；对纤维产量构成因素影响效果较明显，其中株高、径粗、有效株率、单蔸产量与对照差异达到显著水平，而鲜皮厚、鲜皮出麻率未达显著；对纤维品质的影响略有降低，但差异不显著。
篣nder 15℃, optimal soaking concertration and optimal soaking hours was 20% and24h hy PEG(6, 000) pretreatment on ramie seed. It promoted seed germination and raised seed vigor and raised respirtory rate. In addtion ,Pot culture experiment with soaking 24h of 20% PEG pretreatment on ramie seed. To promote growth and development of ramie and to streng then disease-risitant ability. Effect of PEG pretreatment was noticeable to fibre yield factors, of which plant height and stem diamter and effective plants and fibre yield per stool were significant,but bast thickness and fresh bast ratio were No significant The fibre quality was lower than that of the control after PEG pretreatment,but no significant
