简介:在土壤和蔬菜的锑(Sb)的高集中能引起潜在的健康风险。然而,庄稼的生长和反应上的Sb的效果不是众所周知的,迄今为止,仍然为在中国的AlliticUdicFerrisols没有Sb限制标准。在这研究,一个温室实验被执行在生物资源,生理的表演,和宏上调查锑(Sb)的效果--并且绿中国卷心菜(BrassicachinensisL.)的微量元素元素集中,以及酶活动在从湖南省的AlliticUdicFerrisols,中国。锑以0的率(控制)被供应,2,5,10,20,和50mgkg−1并且因此在对待的土壤样品1.0mgkg−1,与背景珍视Sb集中是1,3,6,1121,并且51mgkg−1,分别地。结果显著地显示出卷心菜的叶生物资源和维生素酸内容(P<0.05)分别地,在30.6%和48.3%减少了并且显著地也玷污urease和脱氢酶活动(P<0.05)分别地,在33.6%和32.5%减少了什么时候玷污Sb集中,作为与控制相比是21mgkg−1。象由卷心菜的Mg,Cu,和Zn那样的必要滋养的元素的举起显然被影响,当时当土壤Sb集中超过了21mgkg−1时,可溶的糖内容稍微改变了的叶。把生理的回答和土壤酶活动基于卷心菜,为在AlliticUdicFerrisols的Sb的21mgkg−1的可允许的集中应该被推荐。
简介:淀粉,直链淀粉,蔗糖内容和在在开花以后的shading处理下面的淀粉合成酶的活动的动态变化作为材料用二米饭变化IR72(indica)和Nipponbare(装饰用的梨树)被学习。当仅仅有点改变的自动数据处理葡萄糖pyrophosphorylase(ADPGPPase)活动,可溶性淀粉synthase活动和小粒绑了淀粉synthaseactivity时,在shading处理,thest拱门,直链淀粉和蔗糖下面,内容减少了减少,可溶性淀粉分叉酶(SSBE,Q酶)活动和小粒界限淀粉分叉酶(GBSBE,Q酶)增加的活动,和淀粉初上舞台的人ranching酶(DBE,R酶)活动与变化变化了。关联分析证明淀粉内容的变化断然并且显著地在弱光与蔗糖内容的变化被相关。ADPGPPase活动和SSBE活动断然并且显著地与淀粉累积率被相关。淀粉synthase活动的衰落与淀粉内容的减少有关,淀粉分叉酶的活动的增加在弱光下面在直链淀粉的比率的减少起了一个重要作用到全部的淀粉,这被暗示。

简介:有在吃并且煮的质量的重要差别的四个装饰用的梨树米饭变化在实验被使用。变化在充满阶段的不同谷物在直链淀粉和胶淀粉内容显示出差别,它在充满阶段的不同谷物被归因于淀粉的积聚的速度。在充满时期的谷物期间,变化没在ADPglocosepyrophosphorylase(AGPP)和最可溶的拱门合成(SSS)的活动到达了最大值的时间有差别,但是在淀粉分叉酶(SBE)的活动到达了最大值的时间有差别,在哪个劣等的优秀变化比高质量的早,并且高质量的变化仍然在谷物充满的最近的年龄使酶活动高。在性质与谷物充满的不同阶段改变了的AGPP,SSS,SBE和直链淀粉内容,胶淀粉内容,味道米价值,和RVA之间的关联和关联词度。在SSS活动和味道米价值之间的关联不在谷物充满的整个时期期间是重要的,但是AGPP和SBE的活动与味道米价值有重要或高度重要的关联。它对改进吃并且装饰用的梨树米饭煮在谷物作为父母在迟了的阶段充满或高酶活动的早阶段与低酶活动使用材料的质量有用。
