Polinização controlada em eucaliptos nas empresas florestais brasileiras

Controlled pollination is an important tool in a forest genetic improvement program, which permits to choose parents and make specific crosses maximizing gains and providing superior genotypes in less time than conventional pollination. To verify the needs of the forest companies regarding the conduction of controlled pollination orchards in the breeding program, a specific questionnaire was sent in September 2011 to companies associated to IPEF. The objective of the questionnaire was to collect basic information about the current situation of controlled pollination orchards and check the main difficulties and demands related. It was found that use of the controlled pollination orchard has begun to be used by companies in the Brazilian forest sector just a few years ago and is considered to be very important in breeding programs in order to shorten the time to obtain new genotypes; but there is still need of crucial information regarding the management of these orchards. The main demands are: Basic concepts of flowering induction; homogeneity of flowering; hormonal induction and alternative techniques for flowering; relationship between management and genotypes used; variations in the flowering of different genotypes; management of the orchard in the different phenological phases; process of grafting typesand interaction between graft and rootstock, irrigation systems; species identification and flowering map.
