| 摘 要： | 在云南省低纬高原气候下,将3个不同原产地的12个烤烟资源进行种植,采用多元统计的方法,分析其生物学性状.结果表明,根据其生物学性状的差异初步可分为Ⅰ,Ⅱ两个大类.美国引进与云南自育的烤烟种质资源同属第Ⅰ类,又包括I1,I2两个亚类.两个亚类相比,主要差异表现在生育期的不同,株高、茎围和叶长仅从平均值的对比上有差异,而叶数、节距和长宽比则几乎没有差异.从生育期来看,与Ⅰ1亚类相比,第Ⅰ2亚类（包括GL939和RGH4）表现为,大田移栽至烟株各个生育期均有提前,移栽至团棵提前1-2 d,现蕾期以后每个生育时期都提前8-12 d,整个大田生育期提前约8 d.津巴布韦引进烤烟种质资源属于第Ⅱ类,其生育期表现为大田移栽至烟株生长的各个时期均较晚,团棵期推迟1-2 d,现蕾期以后每个生育时期均推迟10-15 d,整个大田生育期推迟10-15 d.其农艺性状表现为高秆、多叶、节距稀,叶片呈椭圆形.

| Abstract: | Under low latitude plateau climate of Yunnan province,12 flue-cured tobacco resources from three different origins are planted.The results indicated,after applying multi statistic method analyzing their biological characteristics,they could be divide into I and II of two kinds initially according to their biology character differences.The flue-cured tobacco resources from USA and Yunnan of China belonged to type I,which includes I1 and I2 of two subgroups.The two subgroups had remarkable differences in the period of growth and development.Their height,stem girth and leaf length were Secondary.But leaf number,pitch and value of length and width have no obvious differences.In the period of growth and development,the I2 subgroup（including GL939 and RGH4） displayed that each period was ahead of time after tobacco seedlings were transplanted to fields.Rosette stage was 1-2 days ahead of time while each period was 8-12 days ahead of time after squaring stage.And entire field period was 8 days ahead of time approximately.The flue-cured tobacco resources from Zimbabwe belonged to type II.Their all periods of growth and development displayed that rosette stage was 1-2 days postpone of time.Each period was 10-15 days postpone of time after squaring stage,and entire field period was 10-15 days postpone of time.Their agronomic characters appeared long-stalk,long-pitch,multi-leaf,and elliptic leaves. |
