The intrinsic control of uniform and differential growth of plant cells can be traced to a small number of physical parameters. These are cell wall rheology, membrane and tissue hydraulic conductivity, and membrane and tissue solute transport. Water and solute effects are manifested as alterations in turgor pressure. Environmental and biochemical processes always channel their effects through one or more of these parameters. Technical developments such as the pressure probe and Instron tensiometer, together with a reappraisal of older techniques, are beginning to allow assessment of the relative roles of these factors. Although the importance of cell wall rheology is becoming increasingly apparent, there is still insufficient information to allow generalized conclusions regarding the role of turgor pressure in differential growth. This review considers attempts to correlate these parameters with observed anatomical growth patterns.

差异生长的生物物理学

植物细胞均匀和差异生长的内在控制可以追溯到少数物理参数。它们是细胞壁流变学、膜和组织水力传导率以及膜和组织溶质运输。水和溶质的影响表现为膨压的改变。环境和生化过程总是通过这些参数中的一个或多个来引导其影响。压力探头和 Instron 张力计等技术发展以及对旧技术的重新评估，开始允许评估这些因素的相对作用。尽管细胞壁流变学的重要性变得越来越明显，但仍然没有足够的信息来得出关于膨胀压力在差异生长中的作用的概括性结论。
