Hot pepper response to interactive effects of salinity and boron

摘要: An excess of salinity and boron (B) can limit production hot pepper (Capsicum annuum L.), but little is known about the physiological responses, including antioxidant activities, in response to these excesses. We investigated responses defense mechanisms grown under (NaCl) stress at 3 6 dS/mand B 15 30 mg/kg. Dry weight total chlorophyll content decreased with increasing levels. The toxic effect was greater saline conditions. Higher levels resulted increased concentrations leaves. stomatal resistance values as combined increased. Furthermore, salinity, or both activities H 2 O , SOD, POX, APX GR, which oxidative stress, compared control plants. Increases disrupted plant nutrient balance water use, induced secondary substances leading an tissue concentration suppression growth pepper.
