Resumo: Exposure of bulbs to cold, a physiological phenomenon called vernalization, and bulb size are important factors in the production of lily bulbs and flowers. This study aimed to verify the influence of vernalization of bulbs on flowering cut lily plants, as well as the impact of size and shape of harvest on the production and quality of flowers and bulbs. In turn, the way the stems of the plants used for cut-flower production are cropped is of higher importance for the production of new flower bulbs. In this sense, the experiment was conducted in Viçosa, MG, in a greenhouse in a randomized block design, in split splot scheme with three replications, in which the vernalization periods (25, 35 and 45 days at 4 ± 1 C) constituted the plots; bulb sizes (diameters of 3.2-3.8 cm; 2.5-3.2 cm 1.9- and 2.5 cm), subplots and ways to harvest (full harvest of the stem at the required length for the commercial harvest of the flower, commercial stem harvest at the commercial length, maintaining 10cm of stem in the soil; removal of the floral buds as soon as their appearance is observed and harvest at the end of the season), the sub subplots. The bulbs were planted in beds, with 15 x 20 cm spacing. It was evaluated the number of plants that flowered and the number of flowers, the length and the diameter of the floral buds, fresh and dry weights, diameter and plant height as well as number, perimeter and amount of fresh and dry bulbs. There was a decrease in the plant height with the increase of the vernalization period and a reduction of the diameter of the planted bulbs, as well as of the number and the fresh and dry weights of the produced buds. The production of flowers and buds in number, size and weight was directly proportional to the size of the planted bulbs, while the form of harvest with removal of flower buds increased the number, the perimeter and the fresh and dry weights of the buds. Bulbs with diameter between 3.2 - 3.8 cm, stored for 25 days in cold chamber enable greater production of flowers and the highest stem height, factors that favor the increase in market value.

Por sua vez, a forma de colheita das hastes das plantas utilizadas para corte de flor é preponderante na produção de bulbos filhos. Este estudo teve como objetivo verificar a influência da vernalização dos bulbos em plantas de lírio em flor, bem como o impacto do tamanho e forma da colheita na produção e qualidade de flores e bulbos. O experimento foi conduzido em Viçosa, MG casa de vegetação, em blocos casualizados, com parcelas sub-subdivididas, com três repetições, em que os períodos de vernalização (25, 35 e 45 dias, a 4± 1? C) constituíram as parcelas; os tamanhos de bulbo (diâmetros de 3,2- 3,8 cm; 2,5-3,2 cm e 1,9- 2,5 cm), as subparcelas e as formas de colheita (colheita total da haste no ponto de colheita comercial da flor; colheita da haste no ponto comercial, mantendo 10 cm da haste no solo; retirada do botão floral assim que seu surgimento foi observado e colheita no fim do ciclo vegetativo), as sub subparcelas. Os bulbos foram plantados em canteiros, em espaçamento de 15 x 20 cm. Foram avaliados o número de plantas que floresceram e número de flores, comprimento e diâmetro do botão floral, massas fresca e seca, diâmetro e altura da planta e número, perímetro e massa fresca e seca de bulbos. Houve decréscimo na altura da planta com o aumento do período de vernalização e redução do diâmetro do bulbo plantado, assim como do número e da massa seca e fresca dos bulbos produzidos. Já, a produção de flores e bulbos, em número, tamanho e peso, foi diretamente proporcional ao tamanho do bulbo plantado, enquanto a forma de colheita, com retirada do botão floral aumentou o número, o perímetro e as massas frescas e secas dos bulbos. Bulbos com diâmetro entre 3,2 - 3,8 cm, armazenados por 25 dias em câmara fria possibilitam maior produção de flores e a maior altura de haste, fatores que favorecem o aumento do valor de mercado.UEL2017-08-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de CampoPesquisa empírica de campo.application/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2728710.5433/1679-0359.2017v38n4Supl1p2399Semina: Ciências Agrárias; Vol. 38 No. 4Supl1 (2017); 2399-2408Semina: Ciências Agrárias; v. 38 n. 4Supl1 (2017); 2399-24081679-03591676-546Xreponame:Semina.
