Petiveria alliacea L. var. Alliacea vegetative Spreading

Abstract

The aim of this work was to evaluate the proliferation of Petiveria alliacea L. var. alliacea by live stakes in the agroecological conditions in the northwest of Corrientes Province, determining its most appropriate propagation time, substrate and the use of rooting promoters. The analyzed  factors were type of live stake (levels: terminal stakes and intermediate stakes), type of substrate (levels: sand and commercial mixture) and treatment with plant growth regulator (levels: with and without growth regulator). The test was repeated in autumn, winter and spring. Once the results of each test was obtained, the corresponding analysis of variance was carried out after verification of normality and a significance test (Tukey's test at a level α = 0.05) using Infostat software. Statistical analysis was performed for each staking date, main factors were evaluated separately, as well as possible interactions. It was concluded that multiplication by  live  stakes is  a fast  and efficient method of asexual propagation of Petiveria alliacea L. var. alliacea. Intermediate live stakes were the most convenient ones for successful rooting and subsequent sprouting. The treatment of live strakes with ANA would not be necessary while the cutting is carried out in spring and autumn, but it would be convenient  to use it if it is expected to propagate this species through live stakes in winter. The highest percentages of rooting and sprouting were obtained in sand substrate.
