Anatomy and physiology of leaf coffee plants in different fertilizing levels
da Gama, Tamara Cubiaki Pires; Sales Junior, José Carlos; Castanheira, Dalyse Toledo; Silveira, Helbert Rezende de OliveiraThe mineral nutrition is important for the development of the internal structure of coffee leaves, which may favor the physiological characteristics required to optimize the development and productivity of the culture. This study aimed to identify possible changes in anatomy, physiology and productivity in coffee plants at different fertilization levels applied in three consecutive years, from the second year a...
Potential use of anatomical and physiological characteristics in the selection ...
Castanheira, Dalyse Toledo; Rezende, Tiago Teruel; Baliza, Danielle Pereira; Guedes, Janine Magalhães; Carvalho, Samuel Pereira deThe objective was to evaluate the potential use of morphological and physiological characteristics in the selection of coffee progenies. For the anatomical and physiological, were sampled twenty progenies coming from the three types of origins groups of experimental population installed in UFLA. The design was completely randomized with two evaluation periods. The progenies have studied genetic variability has ...
Flowering an leaf water potential in coffee under diferent water regimes and pl...
Castanheira, Dalyse Toledo; Scalco, Myriane Stella; Fidelis, Iraci; Assis, Gleice Aparecida; Pereira, Fábio Santos; Matos, Nagla Maria Sampaio deThe study of water relations in coffee is of utmost importance at all stages of crop development. The aim of this study was to evaluate “pre-dawn” leaf water potential and the total average production of flowers in non-irrigated and irrigated coffee plants under different water regimes in four planting densities over a two-year period. The cultivar Rubi MG-1192 was used, planted in January 2001 in a randomized ...
