摘要
以11个亚麻品种为试验材料,比较温度对不同品种亚麻种子发芽势和发芽率的影响。结果表明:供试的11个亚麻品种的发芽势和发芽率均随着温度的升高呈单峰曲线变化,5℃处理种子的发芽势和发芽率最低,与其它处理差异达极显著水平,当温度为20和25℃时,亚麻种子发芽势和发芽率最高。通过对11个品种的比较发现,黑亚18在低于10℃的情况下,仍保持了较高的发芽势(85.67%)和发芽率(94%)。
Taking eleven flax varieties as materials ,the effect of temperature on germination energy and germi‐nation rate were studied to provide scientific basis for flax production .The results showed that germination en‐ergy and germination rate of eleven flax cultivars were different ,which presented a single peak curve with the increase of temperature .And germination energy and germination rate of 5℃ treatment was the lowest ,which reached significant difference with other treatments .Germination energy and germination rate were the highest when temperature was 20℃ or 25℃ .It was found that Heiya 18 was kept the higher germination energy and germination rate （85 .67% and 94% ） when temperature was lower than 10℃ .
