Effects of different initiators on the germination of sugar beet seeds
摘要
Abstract
[Objective]To investigate the effects of different concentrations of gibberellin(GA),melatonin(MT),and salicylic acid(SA)priming treatments on the seeds germination and seedling growth of sugar beet,aiming to provide reference for the screening of sugar beet seed initiators.[Methods]Using the domestically bred sugar beet variety NT39106 as the experimental material,GA(50,100,200 and 300 mg/L),MT(50,100,200 and 300 μmol/L)and SA(50,100,200 and 300 mg/L)priming treatments were applied for 8 h,with untreated seeds as the control(CK).Seeds germination and seedling growth parameters of sugar beet were analyzed for each treatment.[Results]The germination potential and germination rate of sugar beet seeds under different concentrations of gibberellin(GA),melatonin(MT),and salicylic acid(SA)treatments were significantly higher than those of the CK(P＜0.05).With the increase of the concentration of the three initiators,the promoting effects on sugar beet seed germination exhibited a trend of initially increasing and then decreasing.Among them,the treatment with 100 mg/L GA demonstrated the best results,and the germination potential and germination rate were up to 91.00%and 93.67%,respectively,followed by the SA treatment,both surpassing the MT treatment.Compared with CK,different concentrations of GA,MT(except for the 300 μmol/L treatment)and SA treatments markedly increased the average bud length and fresh weight of sugar beet seedlings,particularly with the 100 mg/L GA treatment,which resulted in average bud length and fresh weight of 5.43 cm and 0.37 g/10 plants,respectively.[Conclusion]Priming sugar beet seeds with 100 mg/L gibberellin(GA)resulted in better germination performance and remarkably promoted seedling growth.关键词
