Study on Pollination Method and Emasculation Technique for Several Legumes

The pollination ways for Medicago sativa,Medicago falcata,erect Melilotoides ruthenica,Melilotoides ruthenica were studied and seed set rates under artificial emasculation,alcohol emasculation and no-emasculation at different time were counted.The results showed that Medicago sativa,Medicago falcata,erect Melilotoides ruthenica,Melilotoides ruthenica were cross pollinated plants,seed set rate under natural cross pollination was more than 50%;the optimal cross way between Medicago sativa and Medicago falcata was no-emasculation,the optimal cross way between Medicago falcata and Melilotoides ruthenica was artificial emasculation;the optimal emasculation time was 9:00 in morning,optimal pollination time was 24～28 hours after emasculation.
