| ABSTRACT The development of agriculture in the northeastern semi-arid region depends, at least in part, on the correct exploitation and efficient use of natural resources. The objective of this study was to evaluate the effects of the use of saline water on morphophysiological responses and sensory analysis of ‘Boa noite’ plants (Catharanthus roseus) in soil fertilized with bovine biofertilizer. A completely randomized design was used in the split plot arrangement, the plots being formed by the five irrigation water salinity levels (0.5, 2.5, 5.0, 7.5 and 10 dS m-1), and the subplots by two frequencies of application of the 150 mL pot-1 of liquid bovine biofertilizer (divided into one and five times), with five replicates. The analysed variables were: leaf... |

| ABSTRACT Biosaline agriculture is an option for using waters with lower quality. Thus, the objective of this study was to evaluate the growth of ornamental species under irrigation with increasing water salinity levels in two methods of water application. The study was conducted in a greenhouse, in the municipality of Fortaleza, Ceará, Brazil. The treatments were distributed in randomized blocks in split plots, with six levels of water salinity in the plots (0.6 - control, 1.2, 1.8, 2.4, 3.0 and 3.6 dS m-1), two methods of water application in the subplots (localized and sprinkler irrigation) and four ornamental species in the sub-subplots (Catharanthus roseus, Allamanda cathartica, Ixora coccinea and Duranta erecta), with four replicates. Increase in... |

| ABSTRACTThe response of plants to salt stress is an extremely complex phenomenon that involves morphological, physiological and biochemical changes, modifying the leaf contents of chlorophyll and carotenoids, among others and affecting plant growth, development and production. An experiment was carried out from July 2010 to June 2011, in order to evaluate the contents of chlorophyll a, chlorophyll b, total chlorophyll, carotenoids, the chlorophyll a/b ratio and biomass accumulation of shoots and roots of noni plants, when subjected to irrigation and leaching with water of increasing salinity. The experiment was carried out in a greenhouse, at the Center of Agricultural Sciences of the Federal University of Paraíba, in the municipality of Areia-PB, Brazil.... |
