查询词典 ear of maize

The result indicated, the CIMMYT forage characteristics of the overgrowth, strong tillerity and high yield could inherit to the offspring ,and the inherit ability was higher. It was obviously difference of seedling, plant, and its grow habit, flower apparatus and seed between CIMMYT forage and common maize. The hybrid offspring of CIMMYT forage and common maize keep the strong trait of growing and development, but the flower and seed character were look like common maize. The backcross offspring were not different to common maize besides with some tillers, distinct multi-ear and atavism.

结果表明，CIMMYT牧草能将其生长繁茂、分蘖力强、生物产量高的特性遗传给杂交后代，并有较强的世代传递能力；该牧草幼苗、植株及其生长习性、花器官、种子特征等与普通玉米差异明显，其与普通玉米的杂交后代基本保持了它的生长发育特性，但花器官和种子特征更偏向于普通玉米；回交后代除保持了一定的分蘖特性、明显的多穗和返祖现象外，其余特征特性与普通玉米基本没有区别。

By contrast with the WPPM, the other treatments, especially the straw mulching, both of the root and the leafage can not get sufficient growth before July because of the low temperature, and after then, there was plentiful rainfall, so the leafage and stems still accumulated the assimilation products that should be distributed to ear. that led to the reductions of their economic outputs.The yield of maize covered with WPPM was the highest.

秸秆覆盖和露地的玉米在整个生育期内，尤其是秸秆覆盖，出现了各器官生长发育紊乱(如根系、根叶组等生长不充分和茎、穗叶组等过剩生长)的现象，导致了生育后期茎叶与穗争夺有限的光合产物，干物质积累不适时、分配不合理和最终经济产量的降低。

The phenomena of Barren Ear Tip of maize occurs when kernels on the tip of maize ear failed to form or unfertile.

The corn ear rot on 51 malze breeds which were made to national test in Sichuan was investigated in 2005.It showed that the rate of corn ear rot was 35.1%, corn ear rot by Fusarium moniliforme was one of the most important, which was counted for 49.1% in all rot ears investigated.In 2006, the corn ear rot on 12 maize breeds which have different genetic background was investigated again.

通过对2005年国家品种区试四川试点的51个玉米品系穗腐病的调查，结果表明，总的穗腐病发病率为23.2％，其中串珠镰刀菌性穗腐病占49.1％，是主要的玉米穗腐病。2006年8月，又对多营农场的不同遗传背景的12个玉米品系进行了调查，结果表明，总的穗腐病发病率为35.1％，其中串珠镰刀菌性穗腐病占77.1％，也是主要的玉米穗腐病。

The predominant pathogens of maize ear rot and maize stalk rot , Fusarium graminearum and Fmoniliforme, could cause the two diseases by reciprocal infection, and could reach ear from the basal part of stem through stem pith and external dissemination separately.

玉米穗、茎腐病病原学的相互关系研究表明：其优势致病菌禾谷镰孢菌和串珠镰抱菌均可交互侵染引起这两种病害，并且能从植株的外侧和内部由基部向穗部传染，初步证实引起穗腐病的镰孢菌是来自茎腐病的镰孢菌。

4 Mechanisms of the effects on yield and quality With the application of nitrogen, the chlorophyll content, NRase activity, photosynthesis rate, fluorescence parameters in the ear leaves of spring-sown maize and summer-sown maize were affected dramatically, which could affect the yield and quality of maize.
