Tolerance to irrigation water salinity in physalis plants: productive aspects

Biosci. j. (Online); 36 (Supplement1), 2020
The cultivation of non-traditional fruits has gained ground in the horticulture sector, but which, in certain situations, are plants that require previous studies related to soil adaptability, climate, and irrigation water quality. In this sense, this work aimed to evaluate the effects of irrigation wate...

Effect of light and sucrose on photoautotrophic and photomixotrophic micropropagation of Physalis angulata

Biosci. j. (Online); 36 (4), 2020
The biotechnological interest in genus Physalis has increased in the last decades, however, there are still few micropropagation studies of this genus. The objective of this study was to evaluate P. angulata photoautotrophic and photomixotrophic micropropagation with gas exchange under seven li...

Polyploidy induction in Physalis alkekengi

Biosci. j. (Online); 36 (3), 2020
Physalis alkekengi is an ornamental plant that can also be used as a medicinal plant due to its anti-inflammatory, bactericidal, antitumor and fungicidal properties. Polyploidization can be an important tool in the genetic improvement of this species. The objective this work was to obtain tetraploids in ...
