cotyledon

1.Its cotyledon node zone is telome elongation type.

向日葵幼苗节区类为枝伸长。

2.The large amount of PAO could be found in the cytoplasm of parenchyma in cotyledon and in the cell membranes and intercellular spaces of cortical parenchyma in phyllogen.

芽皮层薄壁组织细胞细胞膜、细胞间隙薄壁组织细胞细胞质也有PAO大量分布。

3.The results showed that the levels of arginine and arginase were the highest in cotyledons, which decreased slowly during plant development, followed by leaves and stems, with roots being the lowest.

结果表明，精氨酸含量精氨酸酶活性中最高，且随幼苗生长发育逐渐下降，其次为片茎，根中最低。
