郁金香;杂交种子;发芽率;发芽势
摘  要:
研究了不同浓度GA3和PEG处理对3个杂交组合郁金香种子发芽率、发芽势的影响以及不同采收时期对3个杂交组合郁金香种子萌发的影响。结果表明:GA3处理种子可显著提高种子的发芽率和发芽势,可使发芽率提高7.41%~25.19%,发芽势提高9.63%~25.92%,PEG处理也能提高种子的发芽率和发芽势,发芽率提高幅度为4.44%~19.26%,发芽势提高幅度为3.7%~19.25%;同种处理下授粉后55d采收的3个杂交组合的种子的发芽率分别高达:90.37%、81.48%和77.04%,发芽势分别高达到:85.15%、77.04%和72.59%,为种子的最佳采收时期。

摘  要:
This study was based on the budding vitality and sprout rate of three kinds of tulip hybrid combination seed with different treatments and different seed collection time.The result indicated that seeds of GA3 treatment increased the budding vitality by 7.41%~25.19% and sprout rate by 9.63%~25.92%.PEG treatment also improved budding vitality and sprout rate,PEG treatment increased the budding vitality by 4.44%~19.26% and sprout rate by 3.7%~19.25%.Under the same treatment,seeds harvested on 55 days after pollination had hightest budding vitality and sprout rate.Three different hybrid combinations seeds'budding vitality reached 90.37%,81.48% and 77.04%,respectively,and prout rate increased to 85.15%、77.04% and 72.59%,respectively.
