“…Under abiotic stresses conditions, such as drought, some physiological processes are affected such as photosynthesis, protein synthesis and energy production (Flexas, Bota, Loreto, Cornic, & Sharkey, 2004;Chaves, Flexas, & Pinheiro, 2009). Water relations are also altered and evaluated mainly by the relative water content and water potential in the leaves, with some studies already reporting that for the genus Physalis (Souza & Amorim, 2009;Segura-Monroy, Uribe-Vallejo, Ramirez-Godoy, & Restrepo-Diaz, 2015). Water potential is used as a measure of the plant water status, since it regulates water transport through the membranes.…”

It’s known that drought affects crop growth, however, little is known about the physiological responses developed under these conditions by underexploited species, such as Physalis angulata. This study aimed at assessing the physiological responses of Physalis angulata plants after 40 days under different water availability (100%, 80%, 60%, 40% and 20% of pot field capacity). In this research, the effects of the water deficit on the relative water content, water potential, gas exchange, sugars accumulation and activity of nitrate reductase were evaluated. Water relations were affected mainly in plants under severe water deficit, however, the variables remained stable when cultivated at sub-optimal levels of field capacity. Gas exchanges were also affected by water deficit, with reduction in carbon assimilation, internal carbon, stomatal conductance and transpiration, as well as increased leaf temperature and water use efficiency. Plants accumulated sugars as a mechanism of tolerance to severe water deficit, while nitrate reductase activity was reduced. P. angulata plants develop important strategies to tolerate water deficit, contributing to the establishment of crops under low water availability.

Resumo -O objetivo deste estudo foi estabelecer Physalis angulata in vitro e identificar o meio de cultura mais adequado para a germinação e crescimento inicial da espécie. Nós avaliamos a germinação, o estabelecimento in vitro e o crescimento inicial de suas plântulas em diferentes meios de cultura (MS, WPM e ½MS). Primeiro, foram avaliados porcentagem, tempo médio e índice de velocidade de germinação 15 dias após a inoculação das sementes. Em seguida, foram avaliados número médio de raízes e folhas, comprimento da parte aérea e da raiz, e massa seca da parte aérea, foliar e da raiz de plântulas após 15, 30 e 45 dias da inoculação das sementes. A germinação iniciou-se quatro dias após a inoculação e não foi afetada pelos meios de cultura. Por outro lado, foram observadas diferenças significativas entre os tipos de meio de cultura para a maioria dos parâmetros de crescimento avaliados. Os meios de cultura WPM e ½MS foram mais adequados para o desenvolvimento inicial das plântulas, sendo recomendados para as demais etapas da micropropagação da espécie.

We assessed the germination, in vitro establishment and initial growth of its seedlings in different culture media (MS, WPM and ½MS). First, we evaluated the percentage, average time and speed index of germination 15 days after seed inoculation. Then, we evaluated the average number of roots and leaves, length of shoots and roots, and dry mass of shoots, leaves and roots of seedlings 15, 30 and 45 days after seed inoculation. Germination started four days after inoculation and the choice of culture media did not affect germination. However, significant differences among culture media were found for most growth parameters evaluated. The culture media WPM and ½MS provide better initial growth of seedlings and these are recommended for the other stages of micropropagation of this species.
