澳洲坚果开花与座果习性的调查

Behavior of Flowering and Fruiting of Macadamia Varieties

对澳洲坚果开花及座果习性的调查研究结果表明:澳洲坚果花日开放率与开花进程呈极显著直线正相关关系;品种间花序的开放天数差异显著,花序花朵数差异极显著;澳洲坚果座果率与开花进程呈极显著直线的负相关关系;澳洲坚果落果量最大的是花后20￣50d,落果占总座果数的76%;其次是花后60￣100d,落果占总座果数的14.5%。

Observations of flowering and fruiting of Macadamia trees showed that Macadamia had a highly significantly positive linear correlation between daily flowering rate and flowering process. Flowering days and number of flowers of inflorescence varied significantly among varieties. And a very significantly negative linear correlation was shown between fruit setting rate and flowering process. Fruit fall was found the highest after 20-50 days of flowering, accounting for 76 % of the total set fruits, followed by 14.5 % after 60-100 days of flowering.
