查询词典 Stylosanthes

Study on the variation of PAL activities in the inoculated leaves were closely correlated with the Stylosanthes resistance against anthracnose. The expression level of PAL gene in Mineirao is higher than that in CIAT2312 after inoculation with the test of semi-quantitative RT-PCR. And PAL gene had possible function of resistance to anthracnose.

本研究通过对不同柱花草种质对炭疽病的抗性鉴定，在验证了PAL 在Mineirao 柱花草抗炭疽病方面起一定作用的基础上克隆出PAL 基因，利用半定量RT－PCR 检测该基因在两种柱花草中的差异性表达，分析表明，Mineirao 表达量高于CIAT2312 柱花草，推测出该基因与抗炭疽病有关。

The genetic similarity coefficient analyses The genetic similarity coefficient between 85 accessions and their original backgroud Stylosanthes distributed between 0.6598 and 0.8351, in which No.3 accession was minimum, and No.85 accession was maximum.

在田间表现较好的7个株系中，2号与86号的相似系数最小，为0.6960，遗传距离最远；综合田间观察和AFLP分析，2号株系表现最佳，有望成为替代热研2号柱花草的新品种。

It was shown that the root elongation was inhibited and the malonaldehyde content in root apices and the antioxidase activities of root apices were increased under Al stress (30 μmol/L), while the effects of Al were significantly alleviated by the addition of Si (1.4 mmol/L). Moreover, both Si added before Al treatment and Si added simultaneously with Al treatment could alleviate these effects. On the other hand, the cultivar of Seca was shown to be more sensitive to Al than other cultivars in the absent of Si, while Al-resistance distinction among the cultivars of stylosanthes turned to be non-significant in the present of Si in the pre-cultured solution or both pre-cultured and Al-treatment solutions.

研究结果表明，在铝(30 μmol/L)胁迫条件下柱花草根伸长受阻、根尖丙二醛含量和抗氧化酶活性显著增加，而硅(1.4 mmol/L)处理增加根中硅的含量而降低了铝对根伸长、MDA含量和抗氧化酶活性的影响，且铝处理前12h供给的硅和前处理溶液及铝溶液中均加硅处理的影响均显著；在不加硅条件下西卡品种的耐铝性显著低于其它品种，而经硅预处理的植株和在预处理及铝处理期间均供应硅的植株的耐铝性不同品种间的差异不显著。

Gloeosporioides. The soluble protein of Stylosanthes accessions resistant and susceptible anthracnose was no function to C. gloeosporioides. Leaves structure of two accessions was observed with method of paraffin section.

利用石蜡切片观察，对叶片结构进行分析表明，Mineirao柱花草与CIAT2312柱花草相比，Mineirao柱花草的上表皮细胞较厚于CIAT2312柱花草。

The infection of Stylosanthes anthracnose resulted in Phenylalanine Ammonial- yase and Polyphenoloxidase and Superoxide Dismutase, activities of these three enzymes were increased in Mineirao firstly, while in CIAT2312, they were not similar as that in Mineirao.

Mineirao柱花草和CIAT2312柱花草在炭疽菌作用下，Mineirao柱花草苯丙氨酸解氨酶、多酚氧化酶、超氧化物岐化酶三种酶的活性都是先升后降，而CIAT2312柱花草这三种酶活性升降起伏不定。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
