The white ball (Guazuma crinita Mart, Meliaceae) as one of the most important species in the Ucayali region due to its rapid growth and increasing market value, makes it a competitive species when choosing species for a program of production of goods and sustainable services, therefore determining the amount of biomass plays a key role for this purpose; In this purpose, the 38 trees of G. crinita at 31 months of age, with an average diameter at the height of the base of 13.33 cm, with a maximum and minimum value of 17.4 and 10.2 cm, respectively, with a standard deviation of 1.80 cm and a variability coefficient of 13%, for an average total biomass of 28.76 Kg, with a standard deviation of 10.07 and a variability coefficient of 35%; It was determined that there is a high relationship between the independent variable diameter at the height of the base (dab) and the total aerial biomass of the trees in the Aguaytia river basin according to the biomass model ~ a*dab^b, which resulted which is predictable with the following formula Bmadab = 0.04253*dab 2.5027 with R 2 = 0.9397.
The aim of this study was to determine the influence of air temperature and rainfall on the phenological development of Mauritia flexuosa in plantations located in Ucayali, Peru. For this, during a 24-month period, 191 19-year-old palm trees were evaluated, distributed in three plantations established on low terrace soils. The results showed that the 45% of palm trees did not manifest their sexual maturity, meanwhile, 42% and 13% of individuals with male and female sex, respectively, were verified. It was found that the phenological cycle was biannual, with overlapping phenophases and staggered events. In female individuals, maximum flowering was observed in phenophase FLA1 (4-5%) from September to November 2018 and maximum fruiting FRM1 (4-6%) from October 2018 to January 2019; In male individuals, the FLA2 flowering phenophase occurs in two periods between September 2018 and February 2020, meanwhile, the open flower phenophase of both sexes is synchronous in a higher proportion between September and November. It was determined that pluvial precipitation and air temperature (maximum and minimum) did not show correlation (p ≤ 0.05) with the productive phenophases of Mauritia flexuosa. The pluvial precipitation, the maximum temperature and the minimum air temperature showed null association with each one of the phenological phases of the Mauritia flexuosa palm trees during the evaluation period. In order to obtain information for the planning of silvicultural management activities for the conservation of the species, it is recommended to evaluate for more years the influence of climatic elements on the productive development of Mauritia flexuosa.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
