Oilseed rape (Brassica napus L.) is one of the most important oilseed crops. It has relatively high boron (B) requirements for growth. In this study, a hydroponic experiment was performed to determine the critical B requirement and B distribution in B. napus. The plants were grown for four weeks at a range of B levels (from 0.25 to 1000 µM) supplie...

Oilseed rape (Brassica napus L.) is a high-boron (B)-demanding crop, and initially, normal growing plants might show B deficiency at advanced growth stages on soils with marginal B availability. Hence, we compared the effects of B resupply via roots and leaves on growth and physiological response, and relative expression of B transporters in B-defi...

Ammonium (NH4⁺) and nitrate (NO3⁻) conversely alter pH of the rooting medium, and thus differentially affect the equilibrium between boric acid and borate in soil solution. This can alter boron (B) uptake by plants, which is passive under high, but facilitated (boric acid) or active (borate) under low B supply. Therefore, the effect of NH4⁺ and NO3...

Response surface methodology (RSM) coupled with a central composite design (CCD) was employed to optimize three operating conditions, namely ethanol concentration, time and temperature, for the extraction of phenolic antioxidants from artichoke leaves, demonstrated by total phenolic content (TPC), 2,2′-azinobis (3-ethylbenzothiazoline-6-sulphonic a...
