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。
