请问有人可以解释一下anomalous secondary growth 吗?它跟secondary growth有什么关系?我google了有些说monocot和eudicot都是undergo anomalous secondary growth, 有一些说是一部分的monocot.

可以看看Bio F5 textbook page14

(不要google 了然后copy paste在这里,我自己也会google)

Anomalous means different, for example, some monocots can experience secondary growth, but they are not. What they are actually doing is the parenchyma tissues either divide or enlarge, hence increasing the girth of the stem.

Monocots will never have secondary vascular bundles

Some monocots is under anomalous secondary growth

Eudicots undergo both primary and secondary. Eudicots **never undergo anomalous secondary grwoth**.
