黑米的精米中Ca的含量显著高于白米和红米的精米，白米的米糠中Mn的含量显著高于黑米和红米的米糠；

The Ca content of black milled rice was significantly higher than that of white and red milled rice . The Mn content in rice bran of white rice was significantly higher than those of black and red rice .

随施氮量的增加，颖壳、糠层和精米中Cd浓度均随之增加，但精米Cd浓度在0N（不施氮）与MN（300kgha-1）之间无显著差异。

However , there was no significant difference in the concentration of Cd in the milled rice between 0N ( no nitrogen application ) and MN ( 300 kg ha-1 ) .

各供试亲本整精米率的遗传效应预测值表明，不育系亲本n一32A、恢复系亲本25、30较其它供试亲本能显著的提高整精米率。

Predicted values of genetic effects indicated that the male sterile line II-32A and the restorer lines 25,30 and four hybridized combinations appeared to be useful for the improvement the milled rice percentage .

稻谷、糙米、精米在储藏期对玉米象（Sitophiluszeamais）的抗性差异研究

Relative resistance of rough rice , milled rice , brown rice to the maize weevil ( sitophilus zeamais motschulasky ) during storage

结果：（1）蒸馏水浸泡的糙米在发芽24h前其GABA的含量呈现增加的趋势，发芽24h达到高峰，然后GABA含量呈下降趋势；各发芽阶段糙米中GABA含量均高于糙米和精米。

Result : ( 1 ) Within 24h , the GABA content in brown rice soaked in distilled water increased , then decreased and kept higher than that of brown rice and polish rice in every germination stage .

实验以转基因糙米、非转基因糙米和转基因精米为材料，选择传统的CTAB法、改良碱处理法和高温水煮法提取各样品中的DNA，每个处理设置6个重复。

In this study , traditional CTAB method , improved alkali-treated method and boiling-treated method were used to extract DNA from transgenic brown rice , non-transgenic brown rice and transgenic milled rice samples . For each method , six biological replicates were prepared for each sample .

结果表明：（1）粒长、粒宽、粒重、糙米率和完整精米率5个性状在F2米粒间没有发生遗传分离，它们的遗传受二倍体的母体基因型（F1植株）控制。

The results showed as follows : ( 1 ) No genetic segregation occurred in F2 grains in grain length , grain width , grain weight , brown rice % and head rice % , which indicated these traits are completely controlled by maternal plant genotypes .

糙米和精米的NIR分析效果优于谷粒，可用来分析上述品质性状；谷粒则可用于直链淀粉含量、蛋白质含量的分析。

Among the rice grain , brown rice , milled rice and powder of milled rice , the analytical NIRS results obtained from brown rice and milled rice were better than that of rice grain which was suitable for analyze amylose content or protein content analysis .

从总体上看，齐穗后0～20d的日均气温和日最低气温低，相对湿度大，有利于提高整精米率，降低垩白粒率和垩白度。

Suitable meteorological conditions to increase head rice , decrease chalky rice and chalkiness were high relative humidity , lower mean daily air temperatures and minimum air temperature in the period of 0_20 days after full heading .
