摘要
比较何首乌二倍体、三倍体及同源四倍体在块根产量和品质方面的差异,为筛选优质高产多倍体新品种奠定基础。结果表明:何首乌多倍体表现为块根重显著提高,营养优势明显优于二倍体;三倍体和同源四倍体单株块根有效成分二苯乙烯苷产量是二倍体的2.99倍和1.69倍。与四倍体相比,三倍体在块根产量及二苯乙烯苷产量方面更具优势,在药用植物何首乌优质高产育种中具有高的价值。
Compared the differences of yield characteristics and quality among diploid,triploid and autotetraploid of Polygonum multiflorum Thunb.in order to develop polyploid strains with high yields and qualities.The results showed that roots weight of polyploid were higher than that of diploid.The stilbene glucoside production of per plant of triploid and autotetraploid,respectively,were 2.99 and 1.69 times more than that of diploid.Compared with tetraploid,the average root weight and stilbene glucoside production of triploid had more advantages.Triploid of Polygonum multiflorum Thunb.had higher value in high yield and quality breeding of medicinal plants.
