Generally, the figure of the one in the cave is smaller, the growing speed is very slow and the season growing is not obvious, mainly because of lack of food and the low temperature (around 15℃) in the karst cave water. In the numerable characters, the anal fin, scale of encircle tail and gill raker of the one in the cave are in the tendency of increasing so as to adapt to the narrow water passage in the karst cave, while the length of the cave Cyprinus carpio is lengthening comparing with the one on the surface.
结果表明:从总体看洞穴鲤鱼的体形比地表鲤鱼小,生长速度缓慢,季节生长不明显,主要影响因子是洞穴内食物贫乏和水温较低(15℃左右);在可数性状中,洞穴鲤鱼的臀鳍条、围尾柄鳞和鳃耙有增多趋势,即增加了感觉细胞的附着基底;为适应洞穴水流域的狭窄通道,洞穴鲤鱼的体长相对地表鲤鱼而言有延长现象。

The results showed that with the normal dosage 60g/hm2, inhibiting rate of the plant height and weight of Taiyu 2, Jinzhenzhu, Taiyu 15, Zinuo and other three breeds are beyond 40% and 30%, and it is obvious that plant growing is inhibited, the leaves etiolate and new leaves twist severely and couldn't grow normally. Inhibiting rate of the plant height of Ziyu 2, Taiyu 2, Liaoyu 18, Ludan 50, Zhengdan 958 and some other varieties are between 30.6% and 38.1%, the sensitivity of these varieties are lower and the plant modalities are not influenced bigger; in addition, Nongda 108, Nongda 2008, Xinyu 958 and Taiyu 12 grow healthy, the resistance to nicosulfuron are higher compared with other varieties.

Bamboo variation ofmicrodensity of all age-degree and all height bamboo from bamboo green tobamboo yellow as follows:The downtrend ladder of microdensity the firststage from bamboo green to bamboo yellow is relatively large,normally at theplace 0.35 from bamboo hull(the thickness of from bamboo hull to bambooyellow is 1)micro-density downtrend ladder begin to get smaller,variancerange of microdensity is smaller.When reaching near bamboo yellow area,microdensity reaches its minimum value,and when reaching bamboo yellowsection density increase rapidly,the minimum density of bamboo is only 50% orless of maximum density.Bamboo yellow is comprised of stone cells whichhave thick cell wall,so its density is high,normally 50% to 100% more thanminimum density.Bamboo yellow′s lay thickness is thin,normally the samethickness for all age-degree and all height bamboo,about 0.8mm.From 1 age-degree bamboo to 2 age-degree bamboo during growth,the increase of averagedensity is mainly in bamboo pulp section,from 3 age-degree bamboo to 4 age-degree bamboo,the decrease of average density is mainly decrease in the pulpsection.Same age,same height,the less the density ladder of bamboo radialthickness,the higher the mechanical strength.
所有年龄所有高度的竹材微密度从竹青到竹黄对材性变异规律如下:从竹青到竹黄开始下降梯度较大,一般到相对竹皮距离0.35左右处(整个竹壁厚度为1),竹材微密度下降梯度减小,微密度的变化范围变小,到近竹黄处,微密度达最小值,而后到竹黄部位密度大幅上升,竹材最小密度一般只有最大密度的50%或更低,竹黄由厚壁的石细胞组成,所以密度较大,一般比最小密度增大约50%-100%,厚度较薄,不同年龄不同高度竹材的竹黄厚度相差无几,约在0.8mm左右;竹材从1度竹到2度竹生长过程中,平均密度的增长主要发生在竹肉部分,从3度竹到4度竹生长过程中,平均密度的下降主要发生在竹肉部分,同一年龄同一高度,竹壁厚径向的密度梯度越小,力学强度越高,随着年龄的增大,密度梯度越来越小(1度竹除外),随着高度增加,密度梯度越来越大。

The biological characters of p5CS-bar gene transgenic wheatgrasse and control plants were observed and analysed that none but caudex have marked differences(0.05); The values of plant height、spike length、spike width and stem/leaf are less than control plants, leaf length and leaf width are more than control plants; Under the same condition of growth and climate to compare transgenic wheatgrass with control plants we can see that trning-green sage is advance, defer procreate period, long viridity period, growth speed become slow and the figure of curves is"S", more tillers.

Heddewigii, Dianthus barbatus L, Dianthus latifolius, Dianthus caryophyllus and Dianthus chinensis var. liaotungensis, with relatively high fructification rates and certain traffic tolerance, showed little difference in ecological adaptability and exhibited an average seedling height of 20cm and a mean crown size of 23cm, and pruning during the late growth period could obviously promote flowering and reduce the seedling height by 3cm. While Dianthus barbatus L. and Dianthus phlox subulata, with relatively low fructification rates and higher traffic tolerance, had an unobvious difference in ecological adaptability, which present an average seedling height of 14cm and a mean crown size of 36cm, and pruning during the late growth period could promote flowering to some extent and reduce the seedling height by 2cm.
