蔷薇属植物

Major results were summarized as follows:(1) A total of 58 tree species from 53 genera in 36 families among which 8 species were Rosaceae, 5 species were Liliaceae, 5 species were Eriaceae, 3 species were Ranunculaceae, 3 species were Compositae, 2 species were Cupressaceae, 2 species were Caprifoliaceae, 2 species were Umblliferae, and other 28 tree species were only one receptively. These were recorded in the 8 plots of the A. georgei var. smithii forest;(2) Number of families, genera, species and Margalef index correlated negatively with altitude (P.05), with a peak at 3600 m.(3) Shannon-Wiener index correlated negatively with altitude (P.01), and maintained stable at the altitudes between 3700~4100 m, evenness with altitudes, however, this trend was insignificant.(4) Jaccard index increased sharply with increasing altitude at the altitudes between 3600~4100 m, and was lower between different vegetation types at the altitudes between 4100~4200. Cody index β(subscript c decreased with an increasing altitude, but there were 2 troughs between 4000~4100 m and 4200~4300 m.(5) Maximum tree height H(subscript max and HH(subscript max=37 mcorrelated negatively with altitude (P.05); but basal area and BA BA(subscript max=5.3m^2 correlated with altitudes, however, this trend was insignificant.

结果表明：(1)在调查的8个急尖长苞冷杉林样地内共有植物58种，分属于36科53属，其中植物较多的科有蔷薇科8种、百合科5种、杜鹃花科5种、毛茛科3种、菊科3种、柏科2种、忍冬科2种、伞形科2种，其余的28科各只有1个种；(2)物种科、属、种数、Margalef指数D(下标 M与海拔存在显著的负相关性(P.05)，在分布急尖长苞冷杉最低海拔3600m处出现物种丰富度的最大值；(3)多样性指数与海拔之间有极显著的负相关性(P.01)，并且在3700~4100m之间多样性指数保持稳定；均匀度指数与海拔梯度之间存在负相关性，但不显著；(4)Jaccard指数C(下标 j在海拔3600~4100m随海拔的升高而升高，在生境过渡带的4100~4200m之间Jaccard指数C(下标 j较低；Cody指数β(下标 c随海拔的升高呈下降的趋势，但在4000~4100m和4200~4300m 海拔区间出现2个低谷；(5)最大树高H(下标 max和最大胸径DBH(下标 max与海拔之间存在显著负相关性(P.05)；胸高断面积之和和立木密度与海拔之间存在负相关性，但不显著。

The results showed that pollen in differentfamily or genus of plant have different requirements for phytohormones.The basicmedium of pollen culture supplemented with 2ppm NAA and GA_3 can promotes thepollen germination in Cruciferae.It has been proved that basic medium supplemtedwith 2ppm IAA and GA_3 has special effect on pollen germination and elongation ofpollen tube of woody plant in Rosace...

结果证明：不同科属的植物花粉对激素的要求不同，如在花粉萌发的基本培养基上加2ppm的NAA和GA_3混合液对十字花科植物花粉有促进作用，加2ppm的IAA和GAa_3混合液对蔷薇科木本植物花粉萌发和花粉管伸长有显著效果，而葫芦科植物的花粉在基本培养基上只要有无机盐离子就可以萌发，激素仍有促进花粉萌发的作用。
