Investigating morphological and biological reproductive traits in self-fertile and -infertile macadamia cultivars

记录摘要

Researchers compared flower structure, reproductive timing and pollen-tube growth in macadamia cultivars in Queensland. Differences in flower spacing and timing did not explain the groups' self-fertility. Microscopy showed growth stopping within the style in incompatible pollinations, with outcomes varying between particular crosses and their reciprocal combinations. The experiment measured pollen-tube progression, not harvested yield; pollen dosage was not precisely controlled. The findings support further compatibility research, rather than a universal orchard planting prescription.
