Fitormônios e senescência pós-colheita do brócolos
Provedor de dados: Horticultura Brasileira
Autores: Endres,Lauricio; Finger,Fernando Luiz; Mosquim,Paulo Roberto.
Com o objetivo de avaliar os efeitos do ethephon e GA3 sobre a degradação da clorofila, atividade de peroxidases e respiração durante a senescência pós-colheita do brócolos (Brassica oleracea L. var. italica) cv. Piracicaba Precoce, suas inflorescências foram imersas logo após a colheita, durante uma hora, em 0,1; 1,0; 10; 100 e 1000 mg.L-1 de ethephon e, em um experimento paralelo, pulverizadas com 50, 250 e 1000 mg.L-1 de GA3. O delineamento experimental utilizado foi inteiramente casualizado, com três repetições para a aplicação de ethephon e quatro repetições para a aplicação de GA3. As doses de 100 e 1000 mg.L-1 de ethephon tiveram efeito pronunciado sobre a degradação da colorofila, que foi mais evidente 48 h após a colheita, enquanto o tratamento...

Gas exchange alteration caused by water deficit during the bean reproductive stage
Provedor de dados: Revista Brasileira de Engenharia Agrícola e Ambiental

The purpose of the present study was to analyze gas exchanges in leaves and the parameters of productivity of beans (Phaseolus vulgaris, L.) submitted to two water deficiency periods during which three water regimes were employed: W1 (1,0 ETo during the entire plant cycle); W2 (1,0 ETo up to the flowering period and irrigation interruption from the 37 to the 51st day following sowing, and W3 (in addition to the reproductive phase, water deficit was also applied during the vegetative stage). Photosynthesis was one of the main physiological factors affected by water deficit. This was not only caused by the stomata closure, but also by carboxilation reduction due to metabolic damage. This effect was, however, offset 24 h after rehydration. During flowering,...

Morphological and photosynthetic adaptations of Tabebuia aurea seedlings in the nursery
Provedor de dados: Revista Brasileira de Engenharia Agrícola e Ambiental
Autores: Gonçalves,Eduardo R; Souza,Felipe C.; Santos,Luan N. dos; Silva,José V.; Ferreira,Vilma M.; Endres,Lauricio.
Tabebuia aurea (Benth. &amp;amp; Hook. f. ex S. Moore) (Bignoniaceae) is a boreal species common in Brazil. It is used for ornamental parks and along sidewalks. Its timber is also used for furniture. The objective of this study was to evaluate the effect of nursery shading on the growth and photosynthesis of T. aurea and their photosynthetic adaptation after being transferred to direct sunlight. The T. aurea seedlings were grown under 0, 50, 70 or 95% shade. The photosynthetic active radiation and leaf gas exchange were measured over two distinct periods: 51 (young seedlings) and 70 days after having been sown under each shade treatment. Immediately after the measurements were taken, the seedlings were transferred into full sunlight and the measurements...
