Abstract

Brazil has a considerable variety of species edible fruits, such as strawberry-guava (Psidium cattleianum), which has significant environmental plasticity and great potential for use. Studies related to reproductive biology, involving the knowledge of phenology are efficient tools to contribute to the improvement of species management and conservation strategies. Thus, this study aimed to monitor and record the phenological development of yellow and red Strawberry-guava, contrasting the differences between both. The study was developed in Dois Vizinhos, with red and yellow strawberry-guava, cultivar Ya-Cy, with branches marked at random, proceeding with photographic record and annotations of the peculiarities. The data were presented through images and a detailed description of each phase. The vegetative growth of the red strawberry-guava occurs between July and November, flowering between October and November with fruit ripening from late December to March. The vegetative growth of the yellow strawberry-guava occurs between July and October and between January and April, flowering from September to November and, January to March with fruit maturation between December and February and, from April to September. The red strawberry-guava produced only once a year, while the yellow strawberry-guava tree shows three outbreaks of production in the same period.

Highlights

Brazil has a considerable area of native forest with a variety of species that produce edible, attractive, and tasty fruits (Kohama et al, 2006; Danner et al, 2010a)
Foreign companies and institutions eagerly search for plant resources as happened with the Acca sellowiana, which was neglected in the country, introduced and acclimated in countries outside its natural area of occurrence, such as France, Italy, Russia, United States, Israel, Colombia, and New Zealand
The strawberry-guava (Psidium cattleianum), a native plant originating in southern Brazil, with wide geographical distribution, found from Rio Grande do Sul to Bahia, with significant environmental plasticity in both tropical and subtropical climates, in the most varied edaphoclimatic conditions (Raseira et al, 2004; Franzon et al, 2009; Lisboa et al, 2011) has great potential for exploration, but for this, several basic studies are needed to understand the behavior, limitations, and ways of managing the plant

Summary

Introduction

Brazil has a considerable area of native forest with a variety of species that produce edible, attractive, and tasty fruits (Kohama et al, 2006; Danner et al, 2010a). Other species, which, little explored, stand out as a potential source for several uses, especially food, as, like P. guajava, produce edible fruits (Franzon et al, 2009) These fruit trees may be commercially exploited, aiming at diversifying fruit production and consumption (Danner et al, 2010b). In this scenario, the strawberry-guava (Psidium cattleianum), a native plant originating in southern Brazil, with wide geographical distribution, found from Rio Grande do Sul to Bahia, with significant environmental plasticity in both tropical and subtropical climates, in the most varied edaphoclimatic conditions (Raseira et al, 2004; Franzon et al, 2009; Lisboa et al, 2011) has great potential for exploration, but for this, several basic studies are needed to understand the behavior, limitations, and ways of managing the plant. The objective of this work was to monitor and record the phenological development of yellow and red Strawberry-guava, contrasting the main differences between both
