Chapter goals

The objective of this chapter is to review some of the known responses of vegetable crops to increases in [CO2], temperature and pollutants and to extrapolate vegetable crop responses where data from only agronomic crops is available. Case studies on potatoes, carrots and lettuce are also presented as examples of potential responses.

Because quality is often more important than total yield, in vegetable crops some assessment will be made in this chapter of how global climatic changes may affect vegetable quality. For example, sweet-corn (Zea mays L. subsp. mays) and field maize (Zea mays L.) are classified as the same genus and species, but higher temperatures during sweet-corn ripening may cause premature decline in sugar levels and poor tip-fill. Either problem can make fresh-market sweet-corn unmarketable but only reduces yield in field maize, if there is an effect at all.
