不同来源地半夏出苗规律的研究

Sprouting investigation on Pinellia ternate(Thunb.) Breit collections originated from different places

通过对采自四川、重庆、陕西、江苏各地的不同半夏居群在同一栽培条件下的出苗情况的研究,采用田间实验的方法对39个半夏居群的出苗情况进行了统计分析,为野生半夏的驯化和栽培品种的选育提供依据。实验结果表明,各半夏居群间的出苗率、出苗整齐度差异显著。采自四川简阳(PT16)、四川射洪县皮曼(PT21)、四川遂宁(PT23)、四川蓬安(PT24)、四川遂宁(PT43)、江苏徐州(PT47)、四川安岳(PT49)、四川广安(PT52)八个居群的出苗率较高、出苗期较短、出苗也较整齐。这些居群的半夏适合用于栽培,可大大提高效益。

To study sprouting of different populatons of P. ternata and provide basis of tubers selection, thlrty-nine population of P. ternata originated from different places were collected and cultivated in experimental field with the same cultivable condition. And the rate, the even degree and the time of sprouting were compared and analyzed by SPSS11.0. There is significant difference in the rate, the phase and even degree of sprouting among the populations. The statistical results indicate the population originated from Jianyang County （PT16） ,Shehong County （PT21） ,Suining City （PT23, PT43） ,Peng＇an County （PT24） ,Anyue County （PT49） ,Guang＇an City （PT52） of Sichuan province and Xuzhou City Jiangsu Province （PT47） have relatively high rate,short mean time and high even degree of sprouting.
