1.The results showed that there was highly significantly negative genetic correlation between the number of veins per millimetre of leaf width and the sugar yield per clump. The genetic path analysis showed that the sugar yeild per clump was influenced mainly by the effects of the clump weight and brix.
结果发现,每毫米叶宽含有的叶脉数与丛产糖量有极显著的遗传负相关,遗传通径分析表明,主要是通过影响丛重和含糖分而影响丛产糖量的.
2.The plant height,stem diameter,millable cane per clump,the number of clump and the brix of each sampled cane were measured at the harvest time.
取样的每个植株,收获前分别测定株高、茎粗、有效茎数、丛重和锤度.
3.the genetic distance in seedling generation had a significantly positive relationship with stalk diameter,clump weight and clump weight×brix in hybrids.
有性世代遗传距离和杂种茎径、丛重、丛重×锤度有显著正相关。
4.In order to achieve the best result for selecting sugarcane genotypes with high yield and sugar content, the strategies could be determined to different families based on the direction and degree of genotypic correlations between their brix and 4 yield attributes i. e. plant height, stalk diameter, millable stalks per clump and clump weight.
根据锤度与株高、茎径、茎数和丛重遗传相关的方向和程度,对不同家系高糖高产基因型的选择确定相应的策略,能达到选育高糖高产品种的最佳效果.
5.The results showed that: (1) The additive gene effect was principal in brix, plant height and stalk diameter while the non additive gene effect was greater in clump available stalk numbers, plant biomass, clump weight and brix weight.
结果表明 :(1)锤度、株高和茎径的遗传主要由加性基因效应引起 ,而丛有效茎数、丛重、锤重和地上部鲜重的遗传主要由非加性基因效应引起 ;
6.The number of clump sprout counted to 20-30 Entries, The clump sprouts will stuggy growth when were switched to Subculture medium:MS+1. 0 mg.
约20天后将丛生芽转入除去IAA的培养基继代繁殖，使芽丛健壮生长，继代培养基最优组合为：MS+1.0 mg.
7.The sustainable management technology for D. oldhami is(1) during later middle shooting stage,keeping 2 or 3 new culms per clump i.e.making the culm age structure of clump as 1 year old∶2 year old=2∶1, (2)chopping their top in next early spring and keeping the culms with 7 internode height,which will give 160 500 sub branches·hm -2 sustainablely in each year.
(2 )对上述的绿竹次生枝采萌圃按照竹丛内密度为 3株·丛 -1,丛内结构保持 1龄竹∶ 2龄竹为 2∶ 1,留母竹高度为 7节等技术措施进行改造 ,每年每公顷可获得次生枝 16 0 50 0枝 ,比每年重新营建采萌圃的方法增产 13%左右 ,并能数年持续经营
8.4. The mosses clump on the vegetable garden soil is the best(5.3) when ornamental value is evaluated, the view and admire value of moss clump on the river sand get the lowest grade (1.3), the deal of shading exerts a great influence on score of the vegetable garden soil;
4、菜园土藓丛观赏价值评分最高(5.3),河沙藓丛观赏价值评分最低(1.3),遮荫处理对菜园土基质的得分影响较大;
9.Do you see yonder clump of trees (ie that clump of trees over there)?
你看见那边的一丛树林了吗?
10.The results showed that stalk diameter and brix were mainly controlled by additive gene effects, while the inheritance of clump weight and the millable stalk number per clump were controlled by both additive and non-additive genes.
结果表明 :茎径和锤度的遗传主要受加性基因效应控制 ,而丛重和丛有效茎数的遗传是基因加性和非加性效应共同作用的结果。
