简介：为在米饭的壳硅内容的QTLqHUS6以前位于米饭染色体6的短手臂。由使用在在一个isogenic背景怀有qHUS6的RM587RM19784区域分离的一张F2:3人口，为壳硅内容的二QTL被检测，哪个qHUS6-1在对着丝点近似的区域位于远侧的区域和qHUS6-2。在目标区域带小异质接合的片断的三米饭植物被选择，哪个二盖住qHUS6-1区域，其它盖住qHUS6-2区域。三张F2:3人口分别地从三植物的selfed种子被导出。印射的QTL用在qHUS6-1区域分离的二张人口被执行，并且qHUS6-1被标记RM510和RM19417限定到147.0-kb区域flanked。有在qHUS6-2区域的不同genotypic作文的五组F3线从另外的F2:3人口被选择。二QTL用双向ANOVA，qHUS6-2a位于RM19706RM19795和qHUS6-2b在间隔RM314RM19665定义的间隔被分开。

简介：盆栽试验被进行学习不同的氮应用程序时间的效果(在期间直到ering或孕穗期)与一样，氮在颖果开发和米饭变化Yangdao6的谷物质量评价。增加的氮肥(脲)，特别在孕穗期期间适用，能显然增加milled，雪白大米率和蛋白质与控制(没有氮申请)相比在米饭满足谷物，并且减少白垩的谷物率和直链淀粉内容。而且，增加的氮肥显著地影响了颖果发展并且当氮适用在期间时，提高了粒重直到ering和孕穗期，特别在孕穗期期间。在颖果开发期间，增加的氮肥适用在期间直到ering和孕穗期能显然减少全部的淀粉和直链淀粉内容，然而并非显然为在米饭的胶淀粉内容谷物。氮肥的增加的顶肥，特别在孕穗期期间适用，在amyloplasts和proteinoplasts的发展和结构的有的重要效果。也就是说，它能改变分发，数并且amyloplasts和proteinoplastsin塑造特别在谷物腹部的内乳房间。与控制相比，amyloplasts和proteinoplasts的安排各是更靠近的，与更多的数字，更高的密度和更少的间隙星际ohter。而且，大多数amyloplasts在增加的氮肥水平下面显示出多面体。

简介：与较普通活字大一倍的杂交稻Yangliangyou6(YLY6)和Liangyoupeijiu(LYPJ)，andthree线杂交稻Shanyou63(SY63)作为与谷物充满联合的材料，来源，水池和流动特征被调查。种子背景率，谷物充满度和YLY6和SY63的谷物产量比LYPJ的那些显著地高。在YLY6和SY63的灰煤杆和鞘的事的出口和转变百分比比LYPJ的那些显著地高。在谷物的蔗糖synthase，腺苷diphosphoglucosepyrophosphorylase，淀粉synthase和淀粉分叉酶的活动比为LYPJ为YLY6andSY63是更高的，并且很显著地与充满率，吝啬的谷物充满率，谷物充满度和粒重的最大的谷物被相关。每维管束的区域和YLY6和SY63的韧皮部的小穗状花小穗数字，谷物收益和全部的水池负担是比LYPJ的那些显著地小的，并且越大，越多并且越多降低种子背景率负担更差的谷物充满。交通率每YLY6的区域韧皮部比LYPJ或SY63的大。Theresults建议YLY6拥有强壮的来源，大水池活动和有效流动，它为它充满的高种子背景率和好谷物放了一个生理的底。
