锈菌

Heteroecious Denoting rust fungi that require two host species to complete their life cycle.

转主寄生：描述某些锈菌必须存在两个寄主才能完成它的生活周期。

The changes of four indexes indicated that the photosynthesis and transpiration of poplar cultivars were influenced by the infection of Melampsora larici-papulina Kleb.

这4个基本生理指标变化说明，栅锈菌侵染寄主后对寄主的光合、蒸腾作用均有影响，而且在亲合性组合中影响显著。

In the lever of isozyme,10 species of Melampsora larici-populina are divided into four groups:the first includes Nm ,GL, H159,CJQ and ZST ;the second is Qh and Bqy, the third is Scb and Ts, Tt is included in the forth group.

在同功酶水平上落叶松-杨栅锈菌主要分为以下四大类：Nm、GL、H159，CJQ和ZST为第一类； Qh和Bqy为第二类；Scb和Ts为第三类；Tt为第四类。

In the lever of DNA,13 isolates of Melampsora larici-populina are divided into four groups:the first is composed of GL and CJQ,the second consists of Ts,Tt,Scb and Nm, the third contains Ha,Hf,H159,ZST,Bqy and Hdao,the last is Qh.

在DNA水平上落叶松-杨栅锈菌主要分化成以下四大类：第一类为：GL和CJQ；第二类为：Ts、Tt、Scb和Nm；第三类为：Ha、Hf、H159、ZST、Bqy和Hdao；第四类为：Qh。

This result fitted with the selection standards of the optimum mutagenic dose of the microbe chemical mutagenesis.Different...

不同毒性的小麦条锈菌生理小种对EMS的敏感性不同，且在离体培养条件下，毒性较弱小种的生活能力及抗逆能力明显强于毒性较强的小种。

For example, many rusts overwinter on alternate hosts.

例如，许多锈菌在转主寄主上越冬。

Stripe rust, caused by Puccinia striiformis f.

小麦条锈病是由小麦条锈菌Puccinia striiformis f。

The resistance to disease of transgenic plants were tested by inoculating leaves with Puccinia coronata var.coronata cummins.

对所得到的转基因草地早熟禾植株人工接种冠锈菌夏孢子进行抗病性鉴定并测定了抗病性相关指标。

Wheat leaf rust caused by Puccinia triticina is one of important diseases of wheat, which seriously reduced the yield of wheat.Resistant cultivars are the most economic, safety and effective ways for minimizing the losses caused by the disease.

由小麦叶锈菌引起的小麦锈病是影响世界小麦稳产高产的重要病害之一，利用抗病品种是防治该病害最经济、安全、有效的方法。

Ug99,found in Uganda in 1999,is a new virulent race of Puccinia graminis f.sp.tritici on Sr31,the backbone of stem rust resistance worldwide.

Ug99是1999年在乌干达首次发现的对最重要小麦抗秆锈病基因Sr31有强毒力的秆锈菌新小种。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
