不同品种白三叶蛋白质含量比较

通过对10个不同白三叶Trifolium repens品种在不同生育期内叶片和全株蛋白质含量的测定分析，结果表明：不同品种或同一品种不同生育期的白三叶蛋白质含量差异极显著（P<0.01），蛋白质含量在生育期内呈单峰曲线变化，并以初花期为蛋白质含量降低的转折点；北京地区适宜种植的白三叶品种为海法、汉口和吉林临江，其最佳利用时期为初花期。

Comparative study on protein content in different white clover varieties

The protein content of leaf and whole plant of ten different white clover varieties were analyzed at different growth stages.The result showed that the difference of white clover protein contents among varieties or growth stages was significant(P<0.01).The seasonal dynamics of protein contents of all varieties exhibited a single peak pattern,and the peak appeared in early flowering stage.Haifa,Hankou and Guizhou wildness ecotype were suitable for Beijing area and the optimal utilization time is early flower...
