以发芽势、发芽率作指标 ,采用GriffingⅡ设计 ,研究了 4因素共 1 1种组合 (包括对照 )对解除两种不种皮色的小麦种子休眠的效果。结果表明 :1 μmol/L的GA3(赤霉素GA3)效果较好 ,在所有组合中 ,以 50℃的高温处理 2 4h后用 1 μmol/L的GA3浸种 1 2h最好 ,能显著提高种子的发芽势和发芽率 ,在小麦夏繁中有一定应用价值。
Taking the germination potential and the germination rate as indexes, the effects of four factors and 11 combinations (including the control) on the dormancy of two kinds of seedless wheat seeds were studied by Griffing Ⅱ design. The results showed that 1 μmol / L GA3 had the best effect. GA3 in 1 μmol / L soaking for 12 h at 50 ℃ for 24 h was the best in all the combinations, which could significantly improve the seed The germination potential and germination rate, summer wheat flour in a certain application value.
