Previous issue date: 2016-07-29 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / The tomatillo center of origin is in Mexico, being the fifth most produced vegetable in the country mainly used in the preparation of traditional Mexican cultural dishes. The principal means of spreading species from the genus Physalis are seeds. Physalis is considered easy to grow because of the quantity of seeds the genus produces, and its high rates of germination. This study aimed to characterize the developmental cycle and compare the growth of tomatillo 'purple' in two light conditions. For this purpose, P. ixocarpa 'purple' was grown in PVC pots with four replications of 10 samples for each treatment, a total of 40 plants per treatment. Evaluation of the seedling emergence was held in a range of 7, 14 and 21 days after sowing. The analysis of other phenophases started up to 26 days after sowing, was maintained throughout the cycle, and held in 14 days intervals. The estimated physiological parameters are the content of chlorophyll a and b, and leaf carotenoids. The plasticity of the species in the study was assessed using growth analysis with the variables height, stem diameter, number of leaves, buds, flowers and fruits, and dry weight of plant growth. Analysis was performed with the variables height, stem diameter, number of leaves, buds, flowers, fruits, dry mass of plants and leaf anatomy. The means of the data were assessed using analysis of variance (ANOVA) and the student T-Test with a 5% significance level. In this study the parameters that were influenced by light were the emergence rate of seedlings, the content of photosynthetic pigments, leaf thickness, period required for the establishment of phenophases, dry weight, fruit production and seed vigor. Although the plants grown in direct sunlight have higher rates of growth, greater production of fruits and viable seeds were obtained in plants grown under shade. / O centro de origem de Physalis ixocarpa ? o M?xico, sendo a quinta hort?cola mais produzida no pa?s, usada principalmente na prepara??o de pratos tradicionais da cultura mexicana. A principal forma de propaga??o de esp?cies do g?nero Physalis ? a partir de sementes, sendo considerada de f?cil cultivo pela quantidade de sementes produzidas e pelas altas taxas de germinabilidade. O presente trabalho teve como objetivo caracterizar o ciclo de desenvolvimento e comparar o crescimento de Physalis ixocarpa Brot. ex Hormen bem como analisar os pigmentos cloroplast?dicos, anatomia foliar e germina??o de sementes oriundos dos frutos produzidos sob duas condi??es de luminosidade. Para tanto, realizou-se o cultivo de P. ixocarpa ?roxa? em vasos de PVC, sendo 4 repeti??es de 10 amostras para cada tratamento, perfazendo um total de 40 plantas por tratamento. As avalia??es de emerg?ncia de pl?ntulas foram realizadas em num intervalo de 7 dias ap?s a semeadura finalizando aos 21, as an?lises das demais fenofases iniciaram-se aos 26 dias ap?s a semeadura sendo mantida por todo ciclo e realizada em intervalo14 dias. O par?metro fisiol?gico avaliado foi o teor de clorofila a e b e caroten?ide de folhas expandidas. A aclimata??o da esp?cie em estudo foi avaliada atrav?s da an?lise de crescimento com as vari?veis: altura, di?metro do colo, n?mero de folhas, bot?es florais, flores e frutos e massa seca das plantas. Foi realizada an?lise de crescimento com as vari?veis: altura, di?metro do colo, n?mero de folhas, bot?es florais, flores, frutos, massa seca das plantas e a anatomia foliar. Os dados foram submetidos ao teste de m?dias com an?lise de vari?ncia seguida pelo Teste T-Student a 5% de signific?ncia. Nesse estudo os par?metros que mostraram-se influenciados pela luminosidade foram a taxa de emerg?ncia de pl?ntulas, os teores de pigmentos fotossint?ticos, espessura do limbo foliar, per?odo necess?rio para o estabelecimento das fenofases, massa seca, produ??o de frutos e vigor das sementes. Apesar das plantas cultivadas a pleno sol apresentarem maiores ?ndices de crescimento, a maior produ??o de frutos e sementes vi?veis foram obtidas em plantas cultivadas em ambiente sombreado.
