The spatial distributions of mangrove populations were studied at Yingluogang of Guangxi,China,by continuous sampling along 360m long strips.The main results are as follows:(1)The soil texture,nutrients and salt content vary remarkably along the sampling strip,from the inner seawall to the outer bare beach where no mangrove occurs.The values of organic matter,total nitrogen,hydrolysable nitrogen,total phosphorus,available phosphorus and total salt are 1.11%~6.67%,0.021%~0.136%,41.6~203.7mg/kg,0.0087%~0.0309%,2.78~14.32mg/kg...

The spatial distributions of mangrove populations were studied at Yingluogang of Guangxi,China,by continuous sampling along 360m long strips.The main results are as follows:(1)The soil texture,nutrients and salt content vary remarkably along the sampling strip,from the inner seawall to the outer bare beach where no mangrove occurs.The values of organic matter,total nitrogen,hydrolysable nitrogen,total phosphorus,available phosphorus and total salt are 1.11%~6.67%,0.021%~0.136%,41.6~203.7mg/kg,0.0087%~0.0309%,2.78~14.32mg/kg and 10.20‰~31.12‰,respectively.(2)The contents of sand,slit and clay in the soils are 57.3%~89.6%,8.1%~29.0% and 2.3%~13.7%,respectively.The sand content increases along the strip from the inner seawall to outer bare beach,while the other soil traits change in the opposite direction.(3)The distribution pattern of Mangrove population veried obviously along the sampling strip.At the interval between 240m and 340m away from the seashore, A.corniculatum population has the highest IV(Important Value) with a range from 91.66 to 175.02 and thereafter its IV decreases gradually as it distributes in the direction towards lang. R.stylosa population becomes dominant at the interval between 40 and 230m away from seashore with the highest IV ranging from 110.66 to 264.86. B.gymnorrhiza population dominates at the range of 0-30 m away from seashore with the IV varying from 213.16 to 250.53,while A.marina and K.candel populations have a relatively low IV as a result of their low populaton density.Mangrove populations distribute in a transitional mosaic pattern from the seawall to the outer beach,with the following sequence of occurrence: B.gymnorrhiza,R.stylosa,A.corniculatum, and A.marina. This distribution pattern is the result of continuous succession processes.(4).Integrated environment gradient analysis illustrates the distribution peak value of A.marina and A.corniculatum populations are both 1,while K.candel,R.stylosa and B.gymnorrhiza populations are 2.5,7 and 10,respectively.This suggests that A.Marina and A.corniculatum are pioneer populations during ecological succession, B.gymnorrhizais is a latesuccession population,and while K.candel and R.stylosais are intermediate-stage populations.(5).The regression model based on the relatonship between mangrove and its environmental factors was established,showing a good representation of the spatial distribution pattern of mangrove populations.It is found that the strip and continue sampling methods are suitable for investigating spatial distribution and ecological succession of mangrove populations.

The results showed that both of the D1 and D2 lines had appeared the chromosome aberrances which including single chromosome, chromosome lagging, chromosome bridge, excessive bally dividing etc. The ratio of chromosome aberrance in D1 and D2 lines are 25.24% and 24.05%, respectively, and there are 9.04%~57.14%...

The results showed that both of the D1 and D2 lines had appeared the chromosome aberrances which including single chromosome, chromosome lagging, chromosome bridge, excessive bally dividing etc. The ratio of chromosome aberrance in D1 and D2 lines are 25.24% and 24.05%, respectively, and there are 9.04%~57.14% chromosome aberrance in observed 30 D2 individuals, which showed the differentiations of PMC in D2 lines comparing with D1 lines. In this research, we also identified the variations of agronomic traits of the D1 and D2 lines, it is obvious that there is few traits changes of D1 lines, but there are more changes of agronomic traits in D2 lines which including plant height, stem rigidity, panicle length, grain number per panicle etc. Some of agronomic traits changes could be used as breeding program such as plant height, harder stem, long panicle etc.

本研究将姿DNA导入中国春小麦,对其后代D1,D2代的花粉母细胞(PMC)减数分裂行为进行了细胞学观察,并对形态性状的变异进行了跟踪统计。D1、D2代的减数分裂过程中均出现了单价体、染色体落后、染色体桥、多极分裂等异常现象。D1代PMC减数分裂变异率为25.54%,但未发现明显的形态性状变异。D2代PMC减数分裂变异率为24.05%,与D1代相比,D2代的PMC减数分裂变异开始分化,观察的出现PMC减数分裂变异的30个单株中变异幅度为9.04%~57.14%。D2代群体形态性状发生了丰富的变异,在株高、茎秆硬度、穗长、穗粒数等方面出现了变异,并且出现了茎秆坚硬、穗长增长、穗粒数增多的优良个体。
