摘要
[目的]筛选适合温室中生产种薯的微型薯大小,为马铃薯种薯温室及田间生产研究提供参考和依据。[方法]以不同等级微型薯为试验材料,分析马铃薯母薯大小对其植株生长势和结薯大小分布特点的影响。[结果]母薯越大,呈出苗早,出苗率高的趋势,母薯大于1.0 g时,出苗天数和出苗率无显著性差异;植株的茎粗和株高随着母薯增大呈变粗、变高的趋势;不同等级母薯形成的块茎大小分布有差异;同等级母薯(除M级别外)所形成的中薯所占比例较高,达40.0%以上。[结论]根据种薯的适当微型化要求,推荐使用1.0 g以上微型薯进行种薯生产。
[ Objective ] The paper was in order to screen the potato size which suitable for greenhouse production. [ Method ] The effects of different grades of potato mother tuber on plant growth power and the size distribution of potato were investigated. The experiment was carried out with different grades of potato. [ Result ] The emergence time advanced and the rate of emergence increased with the increase of the mother tuber weight. There were no significant differences of either emergence time or rate of emergence on above 1.0 g in tuber weight. The stem diameter and plant height increased with the increase of mother tubers weight. There are differences between the tubers size distribution generated by different mother tubers. The middle tubers rate was above 40.0% in the same grade mother tubers. [ Conclusion ] It is recommended to use more than 1.0 g tubers as seed potato according the appropriate miniaturization requirements.
