Influence of different water deficit levels during grain filling on yield and total polyphenols content in spring wheat cultivars

ABSTRACT Wheat (Triticum aestivum L.) is often affected by abiotic stress such as high temperatures and water deficit. Due to this, grain yield can be reduced by a water deficit and an inadequate grain filling as well as affect synthesis of polyphenolic compounds. The aim of this study was to determ...
