摘要
从国外引进木槿属Ｆｕｒｃａｒｉａ级植物１４个种，研究其形态分类、细胞遗传学、生物学特性、利用价值，并比较种间差异．１４个种均属短日照植物，染色体基数为１８．多数为四倍体（２ｎ＝７２）；红麻（Ｈ．ｃａｎｎａｂｉｎｕｓ），Ｈ．ｓｕｒａｔｔｅｎｓｉｓ和Ｈ．ｃｏｓｔａｔｕｓ为二倍体（２ｎ＝３６），Ｈ．ｄｉｖｅｒｓｉｆｏｌｉｕｓ为八倍体（２ｎ＝１４４）．抗根结线虫力强的有玫瑰麻（Ｈ．ｓａｂｄａｒｉｆｆａ），Ｈ．ａｃｅｔｏｓｅｌｌａ，Ｈ．ｓｕｒａｔｔｅｎｓｉｓ等．红麻品种间植物学形态丰富，可分为２９个品种类型；
species of Hibiscus section Furcaria were introduced from worldwide. Theirmorphological classification,cytogenetics,biological characters utilization value,differnecebetween species have been studied.All species belong to short- day crops.Most of them aretetraploids( 2n=72),butH.cannabinus H. surattensisand H.costatusarediploids(2n=36).7 The base chromosome number of H.cannabinus is 18.
