Effect of growing conditions at greenhouse on vitamin E content in sweet pepper (Capsicum annuum L.) fruits

Abstract

The studies on effect of growing conditions on vitamin E content in fruits of two cultivars of sweet pepper (Bendigo F1 and Lamuyo F1) were carried out. The influence of growing substrate type (sphagnum peat or rockwool, Flormin, Poland), season of fruits harvesting (Summer or Autumn) and dosages of mineral Iiquid nutrition were investigated. It was found that fruits of sweet pepper grown in rockwool contained more vitamin E than those from sphagnum peat substrate (ring culture), during Summer harvesting„ ln Autumn differences appeared too. but most of them were not statistically proved. The sweet pepper fruits harvested at Summer contained more vitamin E than fruits from Autumn. There were not significant differences among vitamin E level in fruits of the plants cultivated in rockwool at different dosages of fertilizers.
