Phenology of Campomanesia adamantium (Cambess.) O. Berg in Brazilian Cerrado

Abstract

Campomanesia adamantium is a fruit tree native to Cerrado and important for human consumption as food, herbal medicine and even in the beverage industry. The aim of this study was to evaluate the vegetative and reproductive phenology of C. adamantium plants in the region of Ipameri-GO, the synchronization of phenophases and the correlation with climatic data. Rainfall, relative humidity, average, maximum and minimum temperature, as well as sprouting, flowering and fruiting data of C. adamantium plants were collected between September and December of 2016 and 2017. Graphs were plotted for climatological data and phenological phases. Phenophase synchrony analysis and correlation of these phases with the climate of the region were performed. Sprouting and flowering began before the first rains of the rainy season and the peak of these phenophases occurred in October. Fruiting began in October and peak was observed in November. Sprouting is highly synchronous from the second ten days of October and flowering reveals high synchronicity between the second half of October and the first half of November. Fruiting is considered highly synchronous from the second half of November. Not all plants reach reproductive stages. Sprouting and fruiting are related to the occurrence of rainfall and increase of air RH. Flowering has no correlation with rainfall, air RH and temperature.

Pollination biology of Humiria balsamifera var. floribunda (Humiriaceae) on the coast of Maranhão, Brazil

“…A relative increase in bud/flower production was also observed in the transition period from the rainy to the dry season, and maintenance of the highest bloom in the drier months. A clue to the prolonged and even increased flowering of this species in the dry period may be due to its shrub life habit with sufficient biomass to store water [39], the shallow water table in the restinga of the study region, and the increase in temperature and photoperiod in the period [40,41], or adaptation to the behavior of floral visitors [42], especially bees, with increases in the number of individuals in the flowers in the dry period, as recorded by Pinto et al (2022) [27]. In a restinga environment, the reproductive period of plant species increases in the dry season [24,25].…”

Reproductive phenology, morphoagronomic variability, and selection of mother plants of Hancornia speciosa Gomes (Apocynaceae)

“…Phenological studies involving plant species from the Neotropical savannah demonstrate a pattern of flowering based mainly on precipitation, with greater flower production at the end of the dry season and beginning of the rainy season (Leão-Araújo et al 2019;Godim et al 2020;Novaes et al 2020), similar to the mangaba tree. A greater production of flowers in a short period (September and October) guarantees a concentration of nectar available to the pollinating agents of H. speciosa, which are usually visited by bees, butterflies, and moths (Darrault and Schlindwein, 2005).…”

Use of commercial biostimulator in the ex situ cultivation of a native medicinal plant of Cerrado: Campomanesia adamantium

“…Campomanesia adamantium (Cambess) O. Berg (Myrtaceae) is a fruit plant native of 'Cerrado' of Mato Grosso do Sul, Goiás, Minas Gerais and Santa Catarina (Lorenzi 2008), popularly known as 'guavira'. It is a species that grows in a hot tropic climate, with a shrubs size and can reach 1.5 m in height, flowering occurs from August to October, with fruiting from November to December (Leão-Araújo et al 2019). Propagation is by seed, which are recalcitrant and should be sown after harvest (Dresch et al 2012).…”
