Abstract

Growth of a plant is a consequence of the interaction of all the processes discussed in previous chapters: photosynthesis, long-distance transport, respiration, water relations, and mineral nutrition. By the same token, these physiological processes may be controlled themselves by the growth rate of the plants, as discussed in the preceding chapters; however, what exactly do we mean by plant growth? Growth is the increment in dry mass, volume, length, or area, and it mostly involves the division, expansion, and differentiation of cells. Increment in dry mass, however, may not occur at the same time as increment in one of the other parameters. For example, leaves often expand and roots elongate at night, when the entire plant is decreasing in dry mass because of carbon use in respiration. On the other hand, a tuber may gain dry mass without concomitant change in volume.
