以盆栽小麦幼苗为供试植物，设定培养基质硼浓度分别为0、50、100 mg·kg-1，氯化钠浓度分别为0、1、2 g·kg-1，研究了硼和盐复合胁迫对植物生长的影响。结果表明，硼和氯化钠的单独胁迫均能显著抑制小麦生长；硼浓度为50 mg·kg-1时，氯化钠加重了硼对小麦生长的抑制；硼浓度为100 mg·kg-1时，氯化钠缓解了硼对小麦生长的抑制。硼和氯化钠的复合胁迫以及高硼胁迫使根冠比显著增大，氯化钠抑制了小麦对硼的吸收。综合来看，当硼胁迫较严重时，盐胁迫可以促进小麦增大根冠比和减少硼吸收来抵御硼毒害。

To investigate the combined effects of boron(B)and NaCl on the growth of wheat, a pot experiment was conducted using wheat (Triticum aestivum Linn.)seedlings. Boron concentrations of culture medium were set as 0, 50 mg·kg-1 and 100 mg·kg-1, and NaCl concen-trations were 0, 1 g·kg-1 and 2 g·kg-1. The results showed that both boron and NaCl could significantly inhibit wheat growth. At 50 mg B·kg-1, NaCl aggravated growth inhibition caused by boron. At 100 mg B·kg-1, however, NaCl alleviated the inhibition caused by boron. The com-bined stress of boron and NaCl significantly increased the root to shoot ratio of wheat. NaCl inhibited the uptake of boron by wheat. It suggests that under severe boron stress, NaCl is able to alleviate boron toxicity in wheat by increasing root to shoot ratio and reducing boron uptake.
