“…The ability to tolerate water stress enhances the cultivation of these species in areas with low precipitation during the offseason. In addition, high adaptability, low incidence of pests and diseases, and fully mechanized cultivation reduces production costs compared with other winter crops that are more susceptible to biotic and abiotic stresses (Nagaoka and Silveira, 2012).…”

Raphanus sativus L. and Crambe abyssinica Hochst. are promising crops for supplying oil to chemical industries. They are not used for human consumption and can be grown off-season due to their short life cycle. However, drought may limit their growth, photosynthesis and productivity. Thus, the aim of this research was to evaluate the morphological and physiological responses of R. sativus and C. abyssinica subjected to water deficit to identify the strategies used by these species to tolerate the effects of water stress. Two independent experiments for R. sativus and C. abyssinica were conducted with different water replacements: 100% (control), 66% and 33% of the field capacity. The characteristics of water relations, gas exchange, chlorophyll fluorescence, chloroplastidic pigments, morphology and root distribution in the soil profile were evaluated separately in both crops. The results indicate the ability of both species to control water loss. In R. sativus and C. abyssinica, the cell turgor and consequently photosynthesis and growth were maintained even under drought conditions. The maintenance of water status was achieved by osmotic adjustment in R. sativus, and also the root distribution and deepening in both species. Such responses allowed R. sativus and C. abyssinica to be classified as tolerant to drought conditions.
