Germinação in vitro de pólen de híbridos interespecíficos entre o caiaué e o dendezeiro

The purpose of this study was to evaluate the in vitro pollen germination of interespecifics hybrids between caiaue and oil palm (varieties dura, tenera and pisifera). The percentage of pollen germination (PPG) of hybrids ranged from 54.8% to 58.3%. The averages of hybrids and caiaue (73.1%) did not differ statistically, but were lower than the oil palm (84.8%). The germination of pollen of hybrids is sufficient for the successful of crosses in interespecific breeding programmes between caiaue and oil palm.
