The effect of boron (B) on growth, water status and oxidative damage was investigated in the leaves and roots of 7-day-old seedlings of Brassica juncea var. Varuna. For this seedlings of Brassica were grown in solution culture with variable boron supply (0.033, 0.33, 3.3 and 33 mg B L−1) under controlled conditions in green house. Photosynthetic pigments(More)
Antioxidative responses were investigated in leaves of wheat (Triticum aestivum L.) grown at varying S levels ranging from deficiency to excess (1, 2, 4, 6 and 8 mM S). Optimum yield was observed in plants supplied with 4 mM S. Wheat responded to S deficiency and excess supply by decreasing growth of root and shoot. Chlorosis in young leaves was observed(More)
A pot culture experiment was carried out to assess the effect of sulfur stress on growth, oxidative status, and antioxidative metabolism. Onion plants were treated with three different levels of sulfur, namely, 1.0, 4.0, and 8.0 mM S L(-1). Plants raised with 4.0 mM S L(-1) represent sufficient growth for the best vegetative yield. Plants supplied with 1.0(More)
A rapid, simple, sensitive and reproducible RP-HPLC method was developed for the determination of conessine (bioactive steroidal alkaloid) in Holarrhena pubescens, a highly valued medicinal plant extensively used in pharmaceuticals. Separation was achieved on Discovery (R) RP Amide C16 Supelco column (250 µm x 4.6 µm ID) using a mobile phase of(More)
