摘要:

通过对8个不同种源乌拉尔甘草种子萌发及幼苗生长特性的比较研究,结果发现:不同种源乌拉尔甘草种子萌发特性和幼苗形态特征均存在显著差异(P<0.05),遗传多样性指数为1.21~1.91,变异系数为11.05%~83.55%。伊犁种子在各温度下有较高的发芽率,说明其对萌发温度具有较高的耐受性。种子长度、宽度与种子发芽率、发芽指数均呈极显著负相关(P≤0.01),种子千粒重与种子发芽势呈极显著负相关(P≤0.01),株高与种子发芽率呈极显著正相关(r=0.59, P≤0.01)。隶属函数法综合评价表明,赤峰种源品质最好,综合评价D值为0.89,其后依次为会宁和杭锦旗,D值分别为0.83和0.75,可作为人工育种的优质资源。

Abstract:

In this research a comparative study of seed germination and seedling growth characteristics of Glycyrrhiza uralensis germplasm lines of eight different provenances was conducted. It was found that there were significant differences in seed germination characteristics and seedling morphological characteristics among different accessions of G. uralensisP<0.05). The genetic diversity index ranged from 1.21 to 1.91, and the coefficient of variation ranged from 11.05% to 83.55%. Seeds from Yili were found to have higher germination rate at a range of different temperatures, indicating that they tolerate a wide range of germination temperatures. Seed length and width were significantly negatively correlated with seed germination rate and seed germination index (P≤0.01). 1000-seed weight was significantly negatively correlated with seed germination vigor (P≤0.01). Plant height was significantly positively correlated with seed germination rate (r=0.59, P≤0.01). A multi-trait evaluation using a membership function method showed that the quality of seed lines from Chifeng provenance was the best, with a comprehensive evaluation D value of 0.89, followed by Huining and Hangjinqi, with comprehensive evaluation D values of 0.83 and 0.75, respectively. These three germplasm lines could therefore be used as high-quality resources for artificial breeding.
