Fitomassa, produção e qualidade de frutos do meloeiro submetidos à alterações na relação fonte: dreno.

Abstract

The production of melon in the state of Paraíba has been little significant, requiring the import of fruits from other states. therefore, the import of fruit could be reduced by the spread of new farming techniques among producers of Paraíba. In the melon crop, biomass and parts can be manipulated by agronomic practices, interfering with assimilates partition between vegetative and reproductive organs. with various forms of manipulation of relationship source:sink. These changes in relationship source:sink influente on yield and fruit quality at harvest. The objective of this study was evaluate the productivity and quality of muskmelon due to changes in the relationship source:sink. The experiment was conducted during the period from August to November 2012 in the experimental área of the Center for Science and Technology Agrifood, the Federal University of Campina Grande. The treatments were arranged in a randomized block design (RBD) with split plots consisting of the conduct of plata with different number of rods (one atem, two stems and three branches) and the sub-plot of the number of fruits per plant (l and 2 fruits), with four replications. The Mirage hybrid Cantaloupe group was grown in the spacing 2.0 x 0.5 m, being evaluated for growth characteristics, production and fruit quality. The changes induced in melon plant by pruning the stems and fruit thinning provided alterations in the source:sink. The increase in the number of fruits per plant was responsible for the largest percentage of dry matter accumulation in the plant independent of the number of rods.
