Dynamic relationship between flowering habits and podding of 7 alfalfa cultivars
Flowering habits and podding of seven alfalfa cultivars were observed and compared in order to facilitate scientifically reasonable hybridization and improve seed quality of alfalfa.The results showed that in days with clear weather the seven alfalfa cultivars began to flower at about 07 :00 and stopped flowering at about 19 :00 ; their keels generally opened after 09 :00 and in the greatest quantities within 10 :00 ～ 15 :00 during which their insect pollination peaked.All the seven alfalfa cultivars had clear‐cut flowering peaks, i.e., the full‐blooming stages ; they appeared to have a similar podding pattern in which they continuously increased their pods to a certain stable level at the early podding stage and then maintained their pods at this level.Their optimal harvesting periods were the middle ten days of August, and harvesting beyond these periods would result in their seed losses.
