The boron (B) concentration surpasses the plant need in arid and semi-arid regions of the world, resulting in phyto-toxicity. Salicylic acid (SA) is an endogenous signaling molecule responsible for stress tolerance in plants and is a potential candidate for ameliorating B toxicity. In this study, the effects of seed priming with SA (0, 50, 100 and 150 µM for 12 h) on the growth, pigmentation and mineral concentrations of maize (Zea mays L.) grown under B toxicity were investigated. One-week old seedlings were subjected to soil spiked with B (0, 15 and 30 mg kg−1 soil) as boric acid. Elevating concentrations of B reduced the root and shoot length, but these losses were significantly restored in plants raised from seeds primed with 100 µM of SA. The B application decreased the root and shoot fresh/dry biomasses significantly at 30 mg kg−1 soil. The chlorophyll and carotenoid contents decreased with increasing levels of B, while the contents of anthocyanin, H2O2, ascorbic acid (ASA) and glycinebetaine (GB) were enhanced. The root K and Ca contents were significantly increased, while a reduction in the shoot K contents was recorded. The nitrate concentration was significantly higher in the shoot as compared to the root under applied B toxic regimes. However, all of these B toxicity effects were diminished with 100 µM SA applications. The current study outcomes suggested that the exogenously applied SA modulates the response of plants grown under B toxic conditions, and hence could be used as a plant growth regulator to stimulate plant growth and enhance mineral nutrient uptake under B-stressed conditions.

The research work was carried out at the Seed Laboratory of Agronomy Department of Bangladesh Agricultural University, Mymensingh, Bangladesh during the period from March to November in 2008 to find out the effect of different osmopriming techniques on seedling emergence of maize. Seventeen osmopriming techniques viz., T1 = 1% Na2SO4, T2 = 3% Na2SO4, T3 = 5% Na2SO4, T4 = 1% K2HPO4, T5 = 3% K2HPO4, T6 = 5% K2HPO4, T7 = 1% ZnSO4, T8 = 3% ZnSO4, T9 = 5% ZnSO4, T10 = 1% Ca(H2PO4)2, T11 = 3% Ca(H2PO4)2, T12 = 5% Ca(H2PO4)2, T13 = 1% H2O2, T14 = 3% H2O2, T15 = 5% H2O2, T16 = Hydropriming, T17 = Non-priming (control) were used as experimental variables. Different osmopriming methods on seedling emergence performance of maize was evaluated at two moisture levels viz., 30 and 60% moisture of saturated sand in the experiment. Germination percentage, germination index and mean germination time were influenced significantly by osmopriming methods. Seed priming with 3% ZnSO4 showed the highest seedling emergence which was followed by 1% H2O2 and 3% Ca (H2PO4)2. DOI: http://dx.doi.org/10.3329/bjar.v39i3.21986 Bangladesh J. Agril.
