Cobertura plástica e densidade de plantio na qualidade das frutas de Physalis peruviana L.

Abstract

RESUMO Physalis peruviana L. é uma espécie pertencente à família Solanaceae, que vem sendo incorporada em plantios de pequenas frutas, com alto potencial produtivo para regiões subtropicais. Objetivou-se, com este trabalho, avaliar a qualidade das frutas de P. peruviana L., produzidas com ou sem cobertura plástica sobre o dossel das plantas e em duas densidades de plantio (0,5 e 1,0 m entre plantas), sendo de 3,0 m o espaçamento entre linhas. O delineamento experimental adotado foi em blocos ao acaso, em esquema fatorial 2 x 2, com seis blocos e dez plantas por parcela. Foram avaliadas as características qualitativas das frutas, como coloração, quantidade de antocianinas totais, vitamina C, cinzas, sólidos solúveis totais, sacarose, glicose, açúcares totais, acidez titulável, firmeza e umidade. A maior densidade de plantio e o plantio sem cobertura plástica sobre o dossel das plantas resultaram em melhor qualidade das frutas de P. peruviana L.

Characterization of different native american physalis species and evaluation of their processing potential as jelly in combination with brie-type cheese

“…Through the average table (Table 1) it can be seen that the Peruviana, Angulata and Pubences species stood out for higher soluble solids and acidity and the Minimum species stood out due to higher ratio and higher pH. The values found for soluble solids and acidity are in agreement with those of other studies conducted by Bravo et al (2015) and Moura et al (2016b).…”

Desenvolvimento inicial de espécies de fisális submetidas a ambientes de cultivo

“…environment, it was under these conditions that the highest plant height was found for P. peruviana, P. pubescens and also for P. angulata, although this species did not differ from the GRE environment (Table 3). This environment provides temperature and air humidity favorable for the development of seedlings of Physalis species, corroborating MOURA et al (2016), in working with development of papaya seedlings, it was observed that the height of the seedlings was influenced by the environment, occurring further development in shading. Also SILVA et al (2016a) found superior development of yellow passion fruit seedlings in film with 50% and 80% shade.…”

“…In shaded environments the physalis species exhibited a greater quantity of leaves, because in these environments there is a need to increase the photosynthetic surface to maximize light absorption, corroborating MOURA et al (2016) who, working with tamarind seedlings in environments, obtained better results in screen housing. This difference of adaptation observed among species indicates that there is plasticity in their leaves, adapting to the different conditions of shading, adjusting it to the acquisition of light, even in very limiting conditions, such as the offered by shading.…”

Biometric characteristics of fruits and physiological characterization of seeds of Physalis species (Solanaceae)

“…Planting density and spectral light quality studies have been carried out to evaluate the potential and the success of cultivation in Brazilian subtropical areas with P. peruviana (Moura et al, 2016a(Moura et al, , 2016bSilva et al, 2016aSilva et al, , 2016b. The quality of fruits produced in open area systems and dense plantations resulted in better quality fresh weight, anthocyanins, vitamin C, soluble solids, and sugars such as sucrose and glucose (Moura et al, 2016a).…”
