摘要：红花绿绒蒿(Meconopsis punicea Maxim.)为罂粟科(Papaveraceae)多年生草本植物,藏名阿柏几麻鲁,主产于四川西北部、西藏东北部、青海东南部和甘肃西南部海拔2800~4300 m的山坡草地[1]。具有镇痛止咳、固涩和抗菌的功效。红花绿绒蒿野生资源蕴藏量少[2-3],种子萌发率极低,种子休眠与萌发一直备受关注[4-5],但种子品质及调控种子萌发和休眠的内源激素对环境条件的适应性却未有系统报道,不利于红花绿绒蒿资源的保护和利用。
The seed size,1000-grain mass,seed germination indexes after sand storage and endogenous hormone contents before and after sand storage of seeds of Meconopsis Punicea Maxim.from five locations in Qinghai,Sichuan and Gansu Provinces were determined,and the correlations between seed related indexes and geographical factors of locations were analyzed.The results show that germination potential,germination rate and germination indexes of seeds in Dezhuo Mountain in Baima County of Qinghai Province after sand storage are significantly lower than those in other locations;after sand storage,the contents of GA_(3)and IAA in seed of M.punicea from different locations increase,while that of ABA decreases,(GA_(3)+IAA)/ABA ratio and germination rate increase.The 1000-grain mass is significantly positively correlated with altitude.The comprehensive analysis result shows that the(GA_(3)+IAA)/ABA ratio of seeds of Longge Mountain in Jigzhi County of Qinghai Province is the largest,the germination rate is the highest,the germination time lag is short,the seed length,seed width and 1000-grain mass are large,and the seed quality is good.
