Due to large amount of seeds produced by fruits and the fact these seeds germinate easily in different environments, the species of this genus become easy grow. Predicting the ideal point of harvest can lead to increased exploration capabilities of this feature also contributes to obtaining more vigorous seeds for use in studies of propagation and conservation of this important genus. This paper aims to monitor the maturation of fruits and seed viability during fruit development stages. During flowering, the flowers in anthesis were tagged daily until obtaining the number of enough fruit for evaluation. P. ixocarpa fruit were collected at 15, 25, 35, 45, 55 days after anthesis (DAA). In a sample of 50 fruits, it is measuring the length, diameter, fresh weight, color, soluble solids, number and weight of seeds per fruit. The color and pigment content calyx were evaluated and correlated. To determine the quality of seeds at different times of maturation, newly harvested seeds and after drying at room were evaluated for water content, dry mass, germination and seedling emergence. The fruits of P. ixocarpa have more pronounced changes in color only in the calyx. Changes occur in the physical and chemical characteristics to 35 DAA, not differing significantly from the following stages. The physiological seed quality was highest at 45 DAA, indicating this is the best time of maturity for harvest seeds, when the calyx is completely or partially broken and has the yellow green and light yellow brown color and dark green fruit. / O g?nero Physalis ocupa lugar de destaque na fam?lia Solanaceae pela produ??o de frutos para consumo in natura e pela presen?a de metab?litos poli-oxigenados e vitaester?ides em seus tecidos, com ?nfase para as fisalinas, ?s quais se atribuem v?rias atividades farmacol?gicas. Devido a grande quantidade de sementes produzidas pelo fruto e o fato destas sementes germinarem facilmente em diversos ambientes, as esp?cies desse g?nero tornam-se de f?cil cultivo. Predizer o ponto ideal de colheita pode levar ao aumento da capacidade de explora??o desse recurso e contribuir para a obten??o de sementes mais vigorosas para serem utilizadas em estudos de propaga??o e conserva??o desse importante g?nero. Este trabalho tem como objetivo acompanhar a matura??o dos frutos e a viabilidade das sementes durante os est?dios de desenvolvimento do fruto. Flores em antese foram etiquetadas diariamente at? a obten??o do n?mero de frutos suficientes para as avalia??es. Foram coletados frutos de P. ixocarpa aos 15, 25, 35, 45, 55 dias ap?s a antese (DAA). Em uma amostra de 50 frutos foram obtidos o comprimento, di?metro, peso fresco, cor, s?lidos sol?veis totais, n?mero e peso de sementes por frutos. Foram tamb?m avaliados e correlacionados a cor e teor de pigmentos do c?lice. Para determinar a qualidade das sementes em diferentes ?pocas de matura??o, as sementes rec?m-colhidas e ap?s secagem em ambiente foram avaliadas quanto ao teor de ?gua, massa de mat?ria seca, germina??o e emerg?ncia de pl?ntulas. Durante o processo de matura??o, os frutos de P. ixocarpa apresentam mudan?as mais acentuadas na colora??o do c?lice. Ocorrem mudan?as nas caracter?sticas f?sico-qu?micas at? os 35 DAA, ap?s essa fase n?o foram observadas altera??es significativas. A qualidade fisiol?gica das sementes foi m?xima aos 45 DAA, indicando que esta ? a melhor ?poca de matura??o para a colheita de sementes, quando o c?lice encontra-se completamente ou parcialmente rompido e apresenta a cor verde amarelado e marrom amarelado claro e fruto verde escuro.

Tyrimų pagrindimas. Dubravos eksperimentinės mokomosios miškų urėdijos įsigyto šlapio sėklų nusparninimo įrenginio „Nomeco Dewinger B1086” naudojimo instrukcijoje nėra nurodytas optimalus paprastosios pušies ir paprastosios eglės sėklų nusparninimo laikas. Tam, kad optimizuoti šlapio nusparninimo laiką aukščiau minėtame įrenginyje reikalingi tyrimai kaip sėklų nusparninimo kokybė priklauso nuo nusparninimo trukmės. Tyrimo tikslas buvo nustatyti optimalią paprastosios pušies ir paprastosios eglės sėklų nusparninimo trukmę šlapiojo nusparninimo metodu įrenginyje „Nomeco Dewinger B1086”. Tyrimo uždaviniai: (1) atlikti 15, 30, 45, 60 ir 120 minučių trukmės paprastosios pušies ir paprastosios eglės sėklų nusparninimo testus sėklų nusparninimo įrenginyje „Nomeco Dewinger B1086”, kiekvienai rūšiai naudojant tris skirtingas sėklų siuntas, (2) nustatyti paprastosios eglės ir paprastosios pušies sėklų nusparninimo kokybę priklausomai nuo sėklų nusparninimo trukmės. Tyrimo objektas yra sėklų nusparninimo kokybės testai, atlikti sėklų šlapiojo nusparninimo principu veikiančiame nusparninimo įrenginyje „Nomeco Dewinger B1086”. Tyrimo metodai. Kiekvienam iš 15, 30, 45, 60 ir 120 minučių trukmės nusparninimo bandymų buvo naudotos 3 skirtingos paprastosios eglės ir 3 skirtingos paprastosios pušies sėklų siuntos. Kiekvienam tam tikros trukmės ir sėklų siuntos testui buvo analizuoti 4 sėklų bandiniai po 100 sėklų. Viso buvo įvertinta 12 000 sėklų nusparninimo kokybė. Tai rodo aukštą gautų...

However, in its manual, there is no indication how much time it takes to dewing the seeds of pine and spruce. In order to optimize the time of the wet dewinging it is necessary to explore whether the quality of dewinging is influenced by the period of time that the process of dewinging takes. The main aim of the research is to determine the optimal time that a method of a wet dewinging takes with „Nomeco Dewinger B1086”. The Tasks of the Thesis. To perform 15, 30, 45, 60, and 120 min long dewinging tests for the seeds of pine and spruce with a dewinger for the wet seedlots „Nomeco Dewinger B1086”, using three different kinds of seeds of each tree. To detect the quality of dewinging of a pine and a spruce depending on the time the process takes. The objects of the thesis are the tests of the seeds dewinging, carried out with the device „Nomeco Dewinger B1086”. The methods of the Thesis. In each of 15, 30, 45, 60, and 120 minutes long tests of dewinging were used three different kinds seeds of pine and spruce. For each of the time period test were used four samples of the seeds, each consisting of one hundred seeds. All in all, there were 12 000 seeds that were evaluated. It shows great reliability of the research. The quality of the seeds dewinging were classified into four main categories. The data that was achieved during the... [to full text]
