CABI Book Chapter

The physiology of vegetable crops.

Book cover for The physiology of vegetable crops.

Description

This book on the physiology of vegetable crops focuses on the activities and functions of vegetables, defined as herbaceous plants that are harvested for edible parts that can be consumed fresh or with little preparation. Physiology deals with the growth and development processes of these plants, and while this book is focused primarily on the organ and whole-plant level, brief mention of cellular...

Abiotic stress effects on vegetable crops.

This chapter focuses on the effects of high and low temperature, drought and flooding, and salinity on vegetable crops. The stress factors impacting vegetable crops reviewed in this chapter can be grouped into those that can be avoided or moderated by physical structures, such as covers to mitigate cold, and irrigation to overcome drought. Heat, flooding, and salt are more difficult to avoid, and threaten to occur more frequently in this era of rapid climate change. It is fortunate that all these stressors have an effect in common: they subject the plant to dehydration and water loss, and thus elicit common reactions such as stomatal closure, osmotic adjustment, and the production of antioxidants. The similarity of responses thus produces the opportunity to cross-protect the plant from one stress by preceding that stress with a mild form of the same or another stress. This priming process has often been used, for instance in hardening transplants before exposing them to a harsher field environment. It is also possible to develop, through plant breeding, plants that are "pre-primed",or more resistant to abiotic stress factors, but the cost of having higher levels of osmotic substances in place on plant productivity needs to be considered. It is apparent that considerably more effort is needed to translate the understanding of fundamental reactions of plants to abiotic stress into improved plant productivity under field conditions.
