Aims We investigated aerenchyma formation in stems of riparian plants Arundinella anomala and Salix variegate as affected by addition of ethylene and a-naphthalene acetic acid under non-flooded conditions in order to ascertain whether phytohormone ethylene and auxin are direct stimuli for aerenchyma formation in flooded plants.

为了探究乙烯和α-萘乙酸是否是水淹环境条件下植物体内通气组织形成的直接原因，对三峡库区岸生植物野古草和秋华柳在无水淹环境条件下施加乙烯利和α-NAA后茎中通气组织的形成情况进行了研究。

Their reverence for trees can be seen by the way they live. For every tree they cut down, they must plant one seed; when children are born, the parents will then plant a tree which, when one dies, is then made into their coffin, and with each burial, another seed is planted, representing that their life will begin anew. Because of this, Basha village is full of trees and no graves are to be seen.
