Resumo: | Many plant species have properties that can be applied in the pharmaceutical industry, cosmetics, food, among others. However, the environmental conditions under which these species grow, their resistance and tolerance to fluctuations influence on their development. The physiological behavior of the seeds should be studied so that we can better understand the physiology and mechanisms of recovery of seed germination under adverse environmental conditions, thereby establishing protocols for optimizing the germination process. The species Physalis angulata L. belongs to the Solanaceae family and shows promise in studies focused on bioprospecting, especially the production of plant hormones known as physalins. This paper describes the physiological and morphological profiles of seeds of Physalis angulata L. subjected to abiotic stresses. The tests were developed in the Laboratory of Experimental Germination and of the Experimental Forest Garden at the Universidade Estadual de Feira de Santana-BA. Experiments were carried out where the seeds were subjected to different temperatures and osmotic potential (Polyethyleneglycol 6000). Through the heat and osmotic screening could identify the point of priming and establish a protocol of priming for the species. For both the tests of germination in the laboratory and for each treatment were used 4 replicates of 25 seeds in petri dishes and moistened with distilled water or PEG 6000. For the field tests were used 4 replicates of 40 vases (50 cm high and 12.5 cm radius) with seeds primed and not primed. Thus, we observed the response of germination of primed seeds these when subjected to stresses, including comparing seeds of different ages. We conclude that Physalis angulata is a species that tolerates high temperatures and more severe water stress and that priming was effective in older seeds and seedlings from these. |

Entretanto, as condi??es ambientais sob as quais essas esp?cies crescem, a toler?ncia ?s flutua??es, influenciam no seu desenvolvimento desde a fase inicial. O comportamento fisiol?gico das sementes deve ser estudado para que se possa entender melhor os mecanismos de retomada de germina??o das sementes e a qualidade fisiol?gica sob condi??es ambientais adversas, e assim estabelecer protocolos de otimiza??o do processo germinativo. A esp?cie Physalis angulata L. pertence a fam?lia Solanaceae e mostra-se promissora em estudos voltados ? bioprospec??o, principalmente pela produ??o de fitorm?nios conhecidos como fisalinas. Objetivou-se caracterizar os perfis fisiol?gico e morfol?gico de sementes de Physalis angulata L. submetidas a estresses abi?ticos. Os ensaios foram desenvolvidos no Laborat?rio de Germina??o e Campo Experimental da Unidade Experimental Horto Florestal da Universidade Estadual de Feira de Santana- BA. Foram realizados experimentos onde as sementes foram submetidas ? diferentes temperaturas e potenciais osm?ticos (polietilenoglicol 6000). Atrav?s dos screenings t?rmico e osm?tico foi poss?vel identificar o ponto de priming e estabelecer um protocolo de osmocondicionamento para a esp?cie. Para tanto, nos ensaios de germina??o em laborat?rio e para cada tratamento foram utilizadas 4 repeti??es de 25 sementes, colocadas em placas de petri e umedecidas com ?gua destilada ou solu??o de PEG 6000. Para os ensaios em campo foram utilizados 4 repeti??es de 40 vasos (50 cm de altura e 12,5 cm de raio) com sementes osmocondicionadas e n?o osmocondicionadas. Observou-se a resposta germinativa e de crescimento de sementes osmocondicionadas quando submetidas a estresses. Para sementes de diferentes idades verificou-se que as mais velhas apresentaram melhor germinabilidade quando osmocondicionadas. Conclui-se que Physalis angulata ? uma esp?cie que tolera altas temperaturas e restri??es h?dricas mais severas, mais n?o a combina??o destes e que o osmocondicionamento se mostrou efetivo em sementes mais antigas.Submitted by Bruno Matos Nascimento (brunomatos@uefs.br) on 2021-07-12T23:13:17Z No. of bitstreams: 1 Disserta??o mestrado.pdf: 1036767 bytes, checksum: 045266205169f1814672845ca335a3e8 (MD5)Made available in DSpace on 2021-07-12T23:13:17Z (GMT).

Many plant species have properties that can be applied in the pharmaceutical industry, cosmetics, food, among others. However, the environmental conditions under which these species grow, their resistance and tolerance to fluctuations influence on their development. The physiological behavior of the seeds should be studied so that we can better understand the physiology and mechanisms of recovery of seed germination under adverse environmental conditions, thereby establishing protocols for optimizing the germination process. The species Physalis angulata L. belongs to the Solanaceae family and shows promise in studies focused on bioprospecting, especially the production of plant hormones known as physalins. This paper describes the physiological and morphological profiles of seeds of Physalis angulata L. subjected to abiotic stresses. The tests were developed in the Laboratory of Experimental Germination and of the Experimental Forest Garden at the Universidade Estadual de Feira de Santana-BA. Experiments were carried out where the seeds were subjected to different temperatures and osmotic potential (Polyethyleneglycol 6000). Through the heat and osmotic screening could identify the point of priming and establish a protocol of priming for the species. For both the tests of germination in the laboratory and for each treatment were used 4 replicates of 25 seeds in petri dishes and moistened with distilled water or PEG 6000. For the field tests were used 4 replicates of 40 vases (50 cm high and 12.5 cm radius) with seeds primed and not primed. Thus, we observed the response of germination of primed seeds these when subjected to stresses, including comparing seeds of different ages. We conclude that Physalis angulata is a species that tolerates high temperatures and more severe water stress and that priming was effective in older seeds and seedlings from these. |
