Resumo: | This experiment was made with two varieties of garlic, the Amarante and Centenario, under greenhouse conditions, to verify the effect of photoperiods of 9, 12 and 15 hours and natural sunlight on the growth of this vegetable. Plants exposed to photoperiods of 12 and 15 hours received 9 hours of natural light and incandescent light at aproximately 180 lux for the remaining hours. Results showed that the longer the photoperiod the lower the following dry weights in both types of garlic: the total, the exposed parts, sheathes, leaves and roots, and the longer the photoperiod, the lower the total number of leaves and leaf surfaces in the two types of garlic. In the Amarante variety, the highest rates of growth occurred earlier when the photoperiod was longer. In both varieties of garlic, the variations in photoperiods affected the growth of the bulb much more than they did the exposed parts showing that long photoperiods hastened the decrease of the bulbar ratio, and that the longer the photoperiod, the faster the development of the cloves. Plants of the Centenario variety which wore exposed to a photoperiod of 9 hours, showed a high rate of bulb rotting. |

EFFECT OF DIFFERENT PHOTOPERIODS IN THE GROWTH OF TWO GARLIC (Allium sativum L.) CULTIVARSEFEITO DE DIFERENTES FOTOPERÍODOS NO CRESCIMENTO DE DOIS CULTIVARES DE ALHO (Allium sativum L.) This experiment was made with two varieties of garlic, the Amarante and Centenario, under greenhouse conditions, to verify the effect of photoperiods of 9, 12 and 15 hours and natural sunlight on the growth of this vegetable. Plants exposed to photoperiods of 12 and 15 hours received 9 hours of natural light and incandescent light at aproximately 180 lux for the remaining hours. Results showed that the longer the photoperiod the lower the following dry weights in both types of garlic: the total, the exposed parts, sheathes, leaves and roots, and the longer the photoperiod, the lower the total number of leaves and leaf surfaces in the two types of garlic. In the Amarante variety, the highest rates of growth occurred earlier when the photoperiod was longer. In both varieties of garlic, the variations in photoperiods affected the growth of the bulb much more than they did the exposed parts showing that long photoperiods hastened the decrease of the bulbar ratio, and that the longer the photoperiod, the faster the development of the cloves. Plants of the Centenario variety which wore exposed to a photoperiod of 9 hours, showed a high rate of bulb rotting. Este experimento foi realizado em condições de casa-de-vegetação, com dois cultivares de alho, Amarante e Centenário, com o objetivo de verificar o efeito de fotoperíodos de 9, 12, 15 horas e natural, sobre o crescimento dessa hortaliça. As plantas submetidas a fotoperíodos de 12 e 15 horas, receberam 9 horas de luz natural e complementação com luz incandescente, com intensidade luminosa de 180 lux, aproximadamente. Observou-se que quanto mais longo o fotoperíodo, menores o peso seco total, peso seco da parte aérea, peso seco da bainha, pese seco das plantas, peso seco das raízes, número total de folhas e área foliar, em ambos os cultivares. No cultivar Amarante as taxas máximas de crescimento ocorreram tanto mais cedo quanto mais longo o fotoperíodo. Em ambos os cultivares, a variação do fotoperíodo afetou muito mais o crescimento dos bulbos que o da parte aérea, verificando-se que fotoperíodos longos apressaram a queda da razão bulbar, sendo que quanto mais longo o fotoperíodo, mais rápido ocorreu o desenvolvimento dos bulbilhos. Plantas do cultivar Centenário sob fotoperíodos de 9 horas, apresentaram elevada incidência de podridão dos bulbos.Escola de Agronomia - Universidade Federal de Goiás2007-11-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/x-forcedownloadhttps://revistas.ufg.br/pat/article/view/2301Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 8, n. 1, Jan./Dec. 1978; 48-67Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 8, n. 1, jan./dez. 1978; 48-67Pesquisa Agropecuária Tropical; v. 8, n. 1, jan./dez. 1978; 48-671983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/2301/2258Carvalho, Carluce Gomes de Sá eMonnerat, Pedro Henriqueinfo:eu-repo/semantics/openAccess2020-02-26T23:49:43Zoai:ojs.revistas.ufg.br:article/2301Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:55:02.381564Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true |
