For example , a group led by svante p ? ? bo of the max planck institute for evolutionary anthropology in leipzig , germany , analyzed the alleles , or versions , of specific genes in corn cobs recovered from sites in mexico near the origin of corn domestication 德国莱比锡的马克斯普朗克考古人类学研究所帕波的研究团队，分析了从墨西哥玉米栽培起源地附近发现的玉米穗轴中，特定基因的对偶基因（基因型） 。

The results showed that under copper and cadmium stresses sulfur and organic fertilizer fertilization increased the amounts of re - transported storage matter and nitrogen and the rate of transported storage matter and nitrogen in the leaves , leaf sheaths , glumes and spike stalks of wheat and the total amounts of re - transported storage matter and nitrogen and the total rates of transported storage matter and nitrogen in winter wheat before flowering compared with their own controls and the fertilizations with high sulfur and organic fertilizer rates did not presented a remarkable regular effect 结果表明，与各自对照相比，铜、镉胁迫下低施硫和有机肥的处理增加了小麦叶片、茎鞘、颖壳穗轴等营养器官花前贮藏物质、氮素的再运转量和运转率以及营养器官花前贮藏物质、氮素的总再运转量和总运转率，高施硫和有机肥的铜、镉处理则规律性不明显。

The average values of the stomatal index in the non - leaf organs in ca cereals were smaller than those of leaves . blanke put forward a new physiological process in fruit , ' fruit photosynthesis ' , and featured with lower stomatal frequency ( blanke , 1989 ) . the results here also showed that the significant lower stomatal frequency on non - leaf organs , indicating that the new physiological process might exist in these organs of cereals as well 其中小麦芒和颖片有发育较好的叶绿体结构，其基粒数可达普通叶的水平，但比旗叶少；外稃和穗轴都有完整的基粒跺叠，只是跺叠的数量较少；而内稃基粒少，基粒内囊体跺叠不整齐。
