Seed viability Ipomoea arborescens (Humb. & Bonpl. ex Willd.) G.Don

Abstract

Ipomoea arborescens is a tree native to the state of Sonora, of social, economic and cultural importance in rural areas. It is palatable to wildlife and domestic animals. Due to successive anthropogenic issues, a defragmentation of natural ecosystems occurs year after year, causing a low rate in forest populations coupled with global warming that interferes with the quality and quality of the seeds. The objective of this work was to evaluate the viability of white stick (Ipomoea arborescens) seeds using 2,3,5-triphenyltetrazolium chloride at two concentrations (0.5 and 1.0%) and two incubation times (24 and 48 h). A randomized design was used using an ANOVA and a Tukey-Kramer comparison of means with P<0.05. According to the results obtained, there were no significant differences according to the concentrations and evaluation times, showing a viability at 24 h for concentrations of 0.5 and 1.0% from 99.33 to 99.67% and when evaluating the seeds at 48 h. using concentrations of 0.5 and 1.0% was 99.33 to 100%. These values indicate that the seeds of Ipomoea arborescens present an accepted percentage of viability, showing less than 1.0% of non-viable seeds. Therefore, Ipomoea arborescens seeds can be used for reforestation as long as they have an adequate pre-germination treatment.
