| 摘 要： | 选用5种胡萝卜栽培类型共101份材料,调查3a春季栽培先期抽薹发生的基本情况。结果表明,有37份材料抽薹率为0,丹佛斯型、南特斯型、阿姆斯特丹型和黑田型均存在;有5份材料抽薹率高于20%,南特斯型和黑田型各1份,紫根型3份。紫根型平均抽薹率为48.4%,极显著高于其他类型;2004年平均抽薹率为7.0%,极显著高于2005年(2.7%)和2008年(3.7%)。长日照对胡萝卜先期抽薹发生具有一定的诱导效应。

| Abstract: | The premature bolting of carrot(Daucus carota L.var.Stiva DC.)in spring cultivation was investigated with 101 accessions including five ecotypes in 2004,2005 and 2008.The results showed that the premature bolting ratio of 37 accessions of Danvers,Nantes,Amsterdam and Kuroda were zero,and the ratio of one Nantes,one Kuroda and three purple accessions were more than 20 %.The average ratio of purple type was about 48.4 %,which was significantly higher than other ecotypes.The average ratio of 2004 was 7.0 %,whi... |
