“…When temperature was increased from 20˝C day/10˝C night to 30˝C day/20˝C night, a 13%-20% reduction in mean carrot seed mass was found [59], which was associated with a reduction in seed filling time rather than any difference in seed relative growth rate. Daytime temperatures of 20 to 30˝C caused devernalization in radish [60], and a similar response has been recorded in vegetable brassicas [61,62]. Increasing temperature from 17˝C to 26˝C significantly reduced radish pod number and seeds per pod [63], and a reduction in cabbage (Brassica oleracea L.) seed yield was associated with increasing temperature during pod setting [64].…”

Food security depends on seed security and the international seed industry must be able to continue to deliver the quantities of quality seed required for this purpose. Abiotic stress resulting from climate change, particularly elevated temperature and water stress, will reduce seed yield and quality. Options for the seed industry to adapt to climate change include moving sites for seed production, changing sowing date, and the development of cultivars with traits which allow them to adapt to climate change conditions. However, the ability of seed growers to make these changes is directly linked to the seed system. In the formal seed system operating in developed countries, implementation will be reasonably straight forward. In the informal system operating in developing countries, the current seed production challenges including supply failing to meet demand and poor seed quality will increase with changing climates.

“…Brassica vegetables, also known as 'cruciferous vegetables', consist of a large group of herbaceous plants that include some of the world's most cultivated vegetables, namely cabbage, broccoli and cauliflower. Besides their main use as food ingredients, Brassica vegetables are full of antioxidants that help lower the potential risk of different types of cancers and coronary heart issues and are an important source of vitamin C, folic acid and numerous minerals of those biologically active compounds is glucosinolates, sulphur-containing phytochemicals with strong anti-cancer properties [2][3][4]. Brassica vegetables contain significant amounts of carotenoids such as zeaxanthin and lutein, two important components of the macula lutea region of the retina, and, therefore, play an important role in the prevention of age-related macular degeneration [5].…”

This chapter describes recent research studies about kohlrabi, a versatile vegetable with important health benefits (e.g. reduces risk of breast and prostate cancer, improves body metabolism, helps in weight loss diets, etc.). The investigations are focused on pale-green kohlrabi giving an accurate and precise description, from a qualitative point of view, of the bioactive compounds found in different parts of the pale-green kohlrabi: core, peel, leaves and equal combinations between these parts. All the active principles from palegreen kohlrabi are extracted following a well-established method, in an aqueous medium at a constant temperature of 4°C for 24 h. The qualitative screening of phytochemicals gives details regarding the presence or absence of chemical compounds using different colour reactions.

Bolting and premature flowering of lettuce plants are undesirable phenomena that can render production of unmarketable plants. This study was conducted to evaluate the effect of paclobutrazol, a plant growth retardant, on lettuce. Paclobutrazol was applied as a foliar spray (0, 50, 100, 200, 400, 600 mg.L -1 ) and as a soil drench (500, 1000 mg.L -1 ) on lettuce cv. Balady after 30 days of transplanting during 2013-14 and 2014-15 seasons. The results indicated that the paclobutrazol significantly suppressed vegetative growth and consequently reduced yield. Moreover, the application of paclobutrazol during vegetative phase either as a foliar or drench application affects the propensity of plants to bolt. Foliar spray with 200 mg.L -1 retarded flower initiation and bolting about 14 days with minimal effect on vegetative growth and yield characters. The paclobutrazol treatments showed an increase in total soluble solids and dry matter content. The foliar spray treatments showed a low inhibitory effect than soil drench treatments. Besides, the foliar spray at low concentrations (50 -100 mg.L -1 ) exhibited the less inhibitory effect for vegetative and yield characteristics, whereas the high concentrations (400 -600 mg.L -1) resulted in a sharp reduction. Generally, the foliar spray exhibited acceptable results than soil drench method. It is recommended to treat plants, at vegetative phase, with 200 mg.L -1 of PBZ as a foliar spray to delay bolting about two weeks.
