Effects of Various Types and Concentrations of Hormone on Softwood Cutting Propagation of Three Fruit Mulberry Varieties
To facilitate the rapid reproduction and extensive utilization of superior fruit mulberry varieties, this study inves-tigated the effects of different hormone types ( ABT-1, IBA and NAA) and concentrations on the survival rate and growth characteristics of softwood cuttings from three fruit mulberry varieties.The optimal treatment conditions were determined by using queuing score and formula score.The results revealed a significant improvement in the survival rate of three fruit mulberry varieties under various treatments compared to the control group.Furthermore, the three factors ( variety, hor-mone concentration, and hormone type) exhibited an exceptionally significant impact on the survival rate, with variety being the most influential, followed by hormone concentration and hormone type.Overall, the different hormone types and concentrations significantly enhanced the new shoot weight, new shoot length, root weight, root number, total root length, root diameter, and root tips across all three fruit mulberry varieties.Through comprehensive evaluation, it was de-termined that IBA had the greatest promoting effect on softwood cutting of Taiwan Daguosang and Hongguo 2, followed by NAA and ABT-1 for Taiwan Daguosang, ABT-1 and NAA for Hongguo 2, respectively.Both optimal treatment conditions were 200 mg/L IBA.Conversely, for Taiwan Si-jiguosang, ABT-1 exhibited the highest promoting effect, followed by NAA and IBA.Notably, the optimal treatment combinations were 200 mg/L ABT-1.Under the optimal treatments, the highest survival rate of Taiwan Daguo-sang, Taiwan Sijiguosang, Hongguo 2 were 79％, 96％ and 72％, respectively.Moreover, the each growth indicator of softwood cutting of the three fruit mulberry varieties all performed well.This study provided some theoretical guidance for the further development of efficient and practical mulberry cutting technology, and also provided a reference for the in-depth study of the rooting mechanism of mulberry cutting.
