摘要
为确定不同激素种类、浓度和浸种时间对红河橙种子发芽性状的影响,进行L_(9)(3^(4))正交试验,观测发芽动态,统计发芽率、发芽势和平均发芽时间。结果表明:红河橙种子不同处理组合的发芽率为31.11%~58.89%,发芽势为21.11%~44.44%,平均发芽时间为30.94~35.72 d;9个处理组合之间具有显著(P<0.05)或极显著(P<0.01)差异,其中0.20 g/L GA_(3)和0.30 g/L IBA混合溶液浸种8 h的发芽指标(性状)最优,影响红河橙发芽率的主导因子是IBA,影响红河橙种子发芽势的主导因子是IBA和GA_(3)交互作用,影响平均发芽时间的是GA_(3);0.20 g/L GA_(3)和0.30 g/L IBA混合溶液浸种8 h提高了红河橙种子发芽性状指标,可作为红河橙苗木繁育作为种子的处理措施。
To determine the effects of different hormone types,concentrations and soaking times on the germination characteristics of Citrus hongheensis seeds,an L_(9)(3^(4))orthogonal experiment was conducted.The germination dynamics were observed,and the germination rate,germination potential and average germination time were statistically analyzed.The results showed that the germination rate,germination potential and average germination time of different treatment combinations were 31.11%-58.89%,21.11%-44.44% and 30.94-35.72 days,respectively.There were significant(P<0.05)or extremely significant(P<0.01)differences among the 9 treatment combinations.The optimal germination index(characteristic)was obtained when seeds were soaked in a mixed solution of 0.20 g/L GA_(3)and 0.30 g/L IBA for 8 hours.The dominant factor affecting the germination rate of Citrus hongheensis was IBA,the dominant factor affecting the germination potential was the interaction between IBA and GA_(3),and the dominant factor affecting the average germination time was GA_(3).Soaking seeds in a mixed solution of 0.20 g/L GA_(3)and 0.30 g/L IBA for 8 hours improved the germination characteristics of Citrus hongheensis seeds.It is recommended as a treatment measure for seed germination in the propagation of Citrus hongheensis seedlings.
