At the lower generation (C5) of the autotetraploid eggplant, plant shape index and the ratio of the well-balanced plants (9.19%) are low. The average shape index for 12 strains of the three different female parents is 0.4779. But its genetic rate is: h^2=96.39%±3.52%. Plant shape index shows strong minus correlation with average fruiting ability, it's relique interrelated coefficient is: r=-0.9989 and correlative heritability is: h=-95.22%.

同源四倍体茄子育种选择的较底世代（C5代）株形和结果正常的植株比例很低(9.19%)，3个不同母本系的12个株系株形指数平均为0.4779，株形指数的广义遗传率h^2=96.39%±3.52%，株形指数与植株平均结果数呈极强的负相关性，遗传相关系数r=-0.9989，相关遗传力h=-95.22%。

It is concluded that milk replacer which contented 70% plant protein was beneficial to improve the immune function of the calves, and calf can adapt to high level plant protein better after born 30 days.

综合各指标考虑，代乳粉植物蛋白含量为70%左右时，有利于犊牛免疫机能的发挥，犊牛30日龄以后对70%及以下的植物蛋白含量的代乳粉表现出较好的适应性。

Purpuraristatus, the growth, fertility, chromosome configuration, EST isozyme etc. were analyzed in this paper. The results showed that the growth potentiality of (E. sibiricus×E. purpuraristatus) F2 and (E. purpuraristatus×E. sibiricus) F1 were much stronger than their parents, the plant height of the former was 143.2 cm. The whole plant was reseda, the latter was 129.7 cm. The spike nodding of two hybrids were in the middle of their parents, the anther was yellow; the pollen fertility was 0.02%~0.03%, seed set was 0; the average chromosome configuration of former pollen mother cell at PMC M Ⅰ was 6.90Ⅰ+14. 02Ⅱ, the latter was 7.82Ⅰ+13.59 Ⅱ, and lagging chromosome and bridge fragment were observed at meiosis anaphase Ⅰ the EST of the two hybrids F1 and their parents at tillering stage was some certain different in locus, number and intensity.

结果表明，正交F1和反交F1植株的生长势均很强，正交F1株高143.2 cm、全株浅绿色，反交F1株高129.7 cm、全株灰绿色；正、反交F1的穗型均呈双亲中间型，花药呈黄色，花粉可育率0.02%~0.03%，结实率为0，说明杂种高度不育；正交F1的花粉母细胞减数分裂中期Ⅰ平均染色体构型为6.90Ⅰ+14.02Ⅱ，反交F1为7.82Ⅰ+13.59Ⅱ，减数分裂后期丁有落后染色体和染色体桥等不规则现象；亲本及其正、反交杂种F1分某期幼叶的EST同工酶酶带的位点、数目和强弱均存在一定差异，可作为亲本及杂种在蛋白质水平识别的重要依据。

Based on an appropriate monitoring function, a switching scheme is proposed so that after a finite number of switching, the tracking error can converge exponentially to zero if the plant relative degree is one, or a residual set whose radius is proportional to some design parameters if the plant relative degree is greater than one.

在监控函数的监测下，相关的控制信号经至多有限次切换后将停止切换，系统跟踪误差指数收敛于零(若被控系统相对阶为1)，或收敛于一个正比于设计参数的残集中(若被控系统相对阶大于1)。

Leaves detached from mature plant of resurrection plant Boea hygrometrica R.

Though it can improve the plant tolerance using the CaMV35Spromoter to express the related genes in stress environment, the expression of resistant proteinwastes the energy in normal environment and the accumulation of the protein can inhibit the plantsnormal metabolism, causing the morphology change of the plant, resulting in growth anddevelopment retardment of transgenic plants.

利用组成型表达启动子控制抗性相关基因的过量表达虽然可以提高植物在逆境条件下的抗逆能力，但正常环境条件下细胞内组成型过量表达抗逆蛋白则是一种能量浪费，且正常环境下细胞内的抗逆蛋白长时间过量的积累可能妨碍植物的正常生长代谢，引起植物的形态发生改变，造成转基因植物生长发育严重停滞甚。

Host plant could also influence the competitiveness of rhizobia which shown the interaction between rhizobium and plant.

同时，宿主植物对根瘤菌的竞争结瘤也有着明显的影响。在偏酸的条件下，慢生根瘤菌的生长状况较好竞争结瘤能力强而在偏碱的条件下，快生根瘤菌的竞争能力强。
