- 摘要:
- 以9种百子莲属植物为试材,采用TTC染色法和电导率法对种子生活力进行测定,研究了9种百子莲属种子的千粒重、种子形态、种子生活力及萌发特性;并在7种环境条件下测定9个品种的萌发能力。结果表明:品种5(Agapanthus praecox ssp.minimus ‘Storms River’)、品种8(A.praecox ssp.praecox ‘Floribunda’)种子活力高,品种2(A.inapertus ssp.hollandii)、品种3(A.praecox ssp.minimus ‘Adelaide’)活力低;种子萌发力也有明显不同,品种1(A.comptonii ssp.longtubus)、品种5、品种8种子萌发力较强,品种2、品种3、品种4(A.praecox ssp.minimus ‘Forma’)萌发力差;综合9个品种种子的活力及萌发能力可知,品种5、品种8两种百子莲属植物品种的种子活力及萌发能力较强,适合在国内的园林植物应用及药用种植领域大力推广。
- Abstract:
- Taking nine kinds of Agapanthus L.Her.as material,seed vigor determined by TTC staining method and conductivity measurement,the nine kinds of Agapanthus L.Her.of thousand seed weight,seed shape,seed viability and germination characteristics were studied,and germination ability were measured of nine varieties under 7 environmental conditions.The results showed that variety 5(Agapanthus praecox ssp.minimus ‘Storms River’),variety 8(A.praecox ssp.praecox ‘Floribunda’)of seed vigor was high,and variety 2(A.inapertus ssp.Hollandii),variety 3(A.praecox ssp.minimus ‘Adelaide’)of seed vigor was low.The seed germination were obviously different.Varieties of 1,5,8 seeds germination were stronger,varieties of 2,3,4(A.praecox ssp.minimus ‘Forma’)varieties germination were poor.Comprehensive nine varieties of seed vigor and germination ability,variety of 5,8 of seed vigor and germination ability were stronger,could be applied to the Chinese garden plants and promoting medicinal plant field.
