Abstract

This work aimed to study some aspects of the spread and growth of seedlings of strawberry guava. For this, we developed three chapters. The first chapter deals with the rooting of strawberry guava microshoots Irapuã with different concentrations of IBA (0, 1000, 2000, 3000, 4000 mg L-1). We evaluated the survival and rooting percentage, root number, root length, fresh and dry. We observed positive influence of growth regulators on rooting of microcuttings, however, with little difference between concentrations. In chapter two we studied the influence of semi-hydroponic systems and conventional in the development of seedlings produced from Araçazeiro Irapuã micropile. We evaluated the number of shoots, growth of shoots, secondary shoots and plants with shoot length secondary. We did not observe influence of cropping systems in plant development. In the third chapter, was conducted in a semi-hydroponic system microjardim clonal Irapuã strawberry guava, which was conducted monthly collections of microcutting and evaluated the rooting ability of each collection. It was observed that the cultivation of strawberry guava microstumps in semi-hydroponic system is efficient in producing microcuttings, allowing successive collections. The rooting of microcutting microstumps collected in semi-hydroponic system showed low rates of survival and rooting.
