Viabilidade "in vitro" de gr？os de pólen de bacurizeiro - Clusiaceae

the "bacurizeiro" (platonia insignis mart.) is an amazon fruitful native tree that has marked allogamy and self-sporophytic incompatibility. the aim of this work was to study the pollen germination of "bacury" to admit it is a similar technique to the germination behavior in vivo . the viability in vitro has been used to represent the potential ability of pollen to complete the fertilization process. the tests were conducted under laboratory conditions in a completely randomized design, tested in a 2 x 3 x 4 factorial, where: 2= plant forms (grafted and free-standing 3= pollen stage (pre-anthesis , anthesis and post anthesis) and4 sucrose concentrations (0, 7.5, 10 and 20%), with 10 repetitions. there is difference in pollen germination, and for hand pollination, pollen should be collected at anthesis, while the best medium for the germination in vitro is with 7.5 g of sucrose.
