Abstract:

Using the sugarcane varieties Guitang 29 (GT29), Guitang 42 (GT42), Guitang 49 (GT49), and Guitang 55 (GT55) as materials, a combination of greenhouse pot experiment and field experiment were carried out with the aim of clarifying the effects of α-naphthyl acetate (NAA) and kinetin (KT) presoaking on sugarcane yield, root development, and lodging resistance, and improving the theoretical basis of sugarcane high-quality, high-yield, and lodging-resistant. Investigating the effects of NAA/KT presoaking at various concentrations on the leaf fresh weight, root vigor, root shape, and stalk breaking resistance of newly planted sugarcane. The findings demonstrated that, in comparison to the control treatment, the root vigor, root length, and root volume of GT29 and GT42 increased significantly under greenhouse conditions when the NAA/KT ratio was 20-40. Under field conditions, the combination of NAA 25-50mg/L and KT 1mg/L presoaking treatment had the greatest impact on sugarcane fresh leaf weight and stem yield, root growth, and stalk lodging resistance. During 2019 and 2020 experimental years, leaf fresh weights and yields of four sugarcane varieties were higher than that of the control treatment; root length, root surface area, root volume, root tip number and root dry weight were increased by 33.0%, 39.0%, 43.7%, 27.4% and 44.9%, respectively, stalk lodging resistance increased by 26.0%. It could be concluded that NAA/KT presoaking could increase fresh leaf weight, stem yield, and root vigor of the new planted sugarcane, and promoted sugarcane root development; under field trial, presoaking with NAA 25-50mg/L combined with KT 1mg/L could significantly increase stem fresh yield, root length, root surface area, root tip number, root dry weight and stalk breaking resistance of newly planted sugarcane, thereby improving sugarcane lodging resistance.

Key words: NAA/KT, Sugarcane, Root, Stalk, Lodging resistance
