简介:被尝试在basmati米饭决定质的变化(PusaBasmati1121,PB1121)在在40 浸泡期间;°C到80 ;°C。浸泡温度有重要效果(=0.01)在化学作文,glycemic索引和米饭的淀粉特征上。淀粉内容,明显的直链淀粉内容,粗略的蛋白质内容和在未浸泡的米饭满意的粗略的脂肪被发现分别地,是73.24%,27.26%,8.79%和2.56%,但是这些特点地的差别在浸泡以后被观察。到胶淀粉比率(Am/Ap)的直链淀粉从0.59~0.52减少了(在80点浸泡了 ;°C)。粗略的纤维和粗略的灰内容在浸泡以后增加了。在浸泡米饭的矿物质作文(K,P,S,Ca,Mg,Mn,Fe,Cu和Zn)在擦亮的一样的度被发现是16.46%比未浸泡的米饭高。未浸泡的米饭的Glycemic索引被发现是58.41,但是在在80 浸泡以后减少了到54.31;°C。粘贴性质,扫描电子显微镜图象,和X光检查diffractograms在60 的温度范围建议了淀粉的部分gelatinization;°C到80 ;°C。在米饭(明显的直链淀粉内容,Am/Ap比率和crystallinity率)基于质的变化,这被结束中间的浸泡温度(60 ;°C到70 ;°C)将为PB1121浸泡有用。
简介:从铵孤立的RNA--并且对待硝酸盐的米饭叶子被用来屏蔽差别通过mRNA的表示基因微分显示。72个乐队的一个总数显得重要他们的差别和一些被反向的北、北的污点进一步证实。结果显示出那二基因,A-02(Oryzasativa干旱应力联系了mRNA)并且A-03(Zeamays为TFIIB相关的蛋白质的部分mRNA)在喂铵的米饭叶子是高度起来调整的。酶试金证明二抗氧化的酶,过氧化氢酶和peroxidase的活动,和一种non-enzymic抗氧化剂的内容,谷胱甘肽,比在喂硝酸盐的那些在喂铵的米饭叶子是显著地更高的,显示铵营养可能为米饭是有益的种在生长和开发期间改进压力抵抗。

简介:干旱忍耐层次和抗氧化剂保护机制为阿萨姆的21个传统的米饭变化被评估,印度,与SahbhagiDhan一起(干旱容忍)并且IR64(干旱敏感)作为控制。干旱与聚乙烯乙二醇6000在水耕法的文化被强加(PEG6000)那开始与不同集中被标准化。所有米饭变化在干旱应力下面在生长特征显示出明显的减少(开始在15%点,为7,d在Yoshida为7d由20%PEG6000列在后面中等)。根据标准评估分数(SES),八个米饭变化看高干旱忍耐哪个为进一步生物化学的分析向前被带。把生理的参数基于不同morpho-,SN03(吹袭亚德里亚海沿岸的季节性东北冷风),SN04(ProsadBhog),SN05(可拉树Joha),SN06(Helash吹袭亚德里亚海沿岸的季节性东北冷风),SN08(SalihoiBao),SN12(可拉树Amona),SN20(Ronga吹袭亚德里亚海沿岸的季节性东北冷风)和SN21(Sok-Bonglong)作为答应干旱容忍的变化被识别。非酶的抗氧化剂活动viz,谷胱甘肽,ascorbate和酶的抗氧化剂活动象superoxidedismutase(草皮)那样,过氧化氢酶(猫),guaiacolperoxidase(GPX),ascorbateperoxidase(APX),在所有选择变化的射击和根的谷胱甘肽reductase(GR)作为与控制相比揭示了保护机制的重要水平。在包括在干旱应力下面的草皮,GPX,猫,GR和APX的全面抗氧化剂酶的活动的改进在水应力下面在改编过程反映他们的角色。
