SELECTING CULTIVARS OF BROCCOLI FOR OPTIMAL BIOACTIVE COMPONENTS: THE INFLUENCE OF SALINE STRESS

Consumption of broccoli with a rich bioactive composition and nutritive value is increasing steadily worldwide.
Nowadays, new commercial cultivars, ‘Parthenon’ and ‘Naxos’, are being introduced in production areas (SE Spain) to replace underperformers and low-yield cultivars (i.e., ‘Marathon’, ‘Nubia’, ‘Monaco’, etc.) with a better adaptation to the climatic conditions.
In this work, we studied the yield parameters and composition (glucosinolates and vitamin C) of ‘Parthenon’ and ‘Naxos’ and used ‘Nubia’ as a control cultivar and we also induced saline stress conditions (40 and 80 mM NaCl), representative of the current available irrigation water in Spain. ‘Naxos’ showed the best results in terms of head-quality parameters and phytochemical composition (glucosinolates and vitamin C), with potential for replacing undeperformer cultivars (‘Nubia’) in production areas with similar characteristics (i.e., semi-arid climate, high temperatures, and low quality of the irrigation water) of SE Spain, for producing broccoli of good quality.
