1·And the activity of PAL coincided with the increasing tendency of the Numbers of vessel element in the plumular axis or juvenile stem of robinia and its degree of lignification as well.
PAL活力与刺槐胚轴或幼茎的维管系统即导管分子的数量和木质化程度增长趋势相一致。
2·These genes and polynucleotide sequences are useful regulating the lignification process and plant phenotype.
这些基因和多核苷酸序列适用于调节木质化过程和植物表型。
3·The secondary growth includes several consecutive processes such as vascular tissue differentiation, secondary cell wall deposition, lignification, PCD and heart wood formation.
次生生长包括维管组织形成、次生细胞壁形成、木质化、PCD以及心材形成等过程。
