RESUMO:

Pineapple is a much appreciated fruit and has been standing out among several fruit trees grown throughout the country. Pineapple consumption is almost 60% in natura, and it is estimated that in the months of October to March it is the one with the highest consumption, in relation to the other months. For fresh consumption, it is essential that the fruit has an adequate size and characteristics such as sweetness for the consumer, where it will consequently achieve better prices on the market. Therefore, the objective of this work was to evaluate the occurrence of natural and artificial induction on the characteristics of three pineapple cultivars and to verify the behavior of eight cultivars against the cold, in order to identify a more tolerant cultivar to the induction of natural flowering. The experiment was carried out in the fruit growing experimental area of the State University of Mato Grosso - Unemat, in Tangará da Serra - MT. In both experiments, the design used was randomized blocks. In experiment 1 it was a 3x2 factorial (cultivars x flowering induction), and the evaluated cultivars were Pérola, Jupi and Gigante de Tarauacá. And for experiment two, the cultivars Pérola, BRS Imperial, Jupi, BRS Vitória, Smooth Cayenne, IAC Fantástico, BRS Ajubá and Gigante de Tarauacá were evaluated. The cultivars were left to induce naturally, being evaluated weekly from May to September 2019. In experiment one, for the vegetative characteristics leaf width D and number of active leaves, there was a significant difference at 1% probability and for plant height and leaf length D, there was a significant difference at 5% probability. In experiment two, the cultivars showed a difference for the percentage of naturally induced plants (PPI). The cultivars BRS Imperial and Smooth Cayenne had 0% of induced plants and the cultivar IAC Fantástico had 9%, while the cultivars BRS Ajubá and BRS Vitória had 32 and 31% of induced plants respectively and the cultivars Gigante de Tarauacá, Jupi and Pérola had 100% of the plants naturally induced. It is concluded that with the plant at the proper size, natural flowering does not reduce fruit size and the cultivars Smooth Cayenne, BRS Imperial and IAC Fantástico were tolerant to natural induction of flowering.
