摘要 在柠条锦鸡儿、中间锦鸡儿和小叶锦鸡儿3种柠条中,中间锦鸡儿花期最短;小叶锦鸡儿和中间锦鸡儿的盛花期约在5月中下旬,并在5月下旬、6月上旬进入结实盛期,柠条锦鸡儿较前两者晚约半个月;种子采收前,92.42%的柠条锦鸡儿种子长度大于3mm,完全发育成熟,较小叶锦鸡儿高22.49%,较中间锦鸡儿高21.41%;3种柠条果荚长度均在20mm以上,但在20~30mm、30~40mm两个长度段上的比例分配有较大差距;3种柠条所有果荚的宽度均大于3 mm,但在3~6mm、6~9mm两个宽度段的构成比例有明显差异;柠条锦鸡儿花果总损失率最大,为82.37%;小叶锦鸡儿为75.96%;中间锦鸡儿为65.98%。 The results showed that among 3 kinds of Caraganas,the florescence of Caragana intermedia was the shortest;Full bloom stages of Caragana intermedia and Caragana microphylla were in the middle and last ten-day of May,and turned into seed setting period in the last ten-day of May and the first ten-day of June.That of Caragana korshinskii was later about half a month.92.42% of Caragana korshinskii seeds completely turned into mature,their lengths were all above 3mm,which was 22.49% higher than Caragana microph...
