Seedlings production of duranta Duranta repens L. using cuttings process

Abstract

Due to easy adaptation to climate, soil and ornamental potential, Duranta repens L. is widely used in Brazil. The study evaluated the production of seedlings of D. repens L. using cutting process with the supply of exogenous IBA in different seasons. The experimental design was completely randomized, with four concentrations of IBA (0, 1000, 3000 e 5000 mg kg^-1), three types of cuttings (softwood, semi-hardwood and hardwood) and two seasons (wet and dry). We assessed the number of rooted cuttings, survival cuttings, number of shoots per cutting, average length of the longest root and dry mass of shoots and roots. The best dose for propagation of D. repenswas 3000 mg kg^-1 IBA. The softwood and semi-hardwood cuttings were the most suitable and the rainy season the more favorable for D. repens seedling production.
