| 摘 要： | 为了解花粉活力对澳洲坚果初始坐果率的影响,以高产品种‘南亚2号’和低产品种‘B3/74’为材料,对2个品种的花粉活力及初始坐果率进行了测定和分析。结果表明,‘南亚2号’花粉活力较强,其初始坐果率也较高。‘南亚2号’的花粉染色率和花粉萌发率分别达到89.0%和33.3%,显著高于‘B3/74’的56.7%和8.1%,其柱头上附着的花粉粒数量及花粉萌发量也显著多于‘B3/74’,‘南亚2号’的初始坐果率为10.9%,显著高于‘B3/74’的9.0%。

| Abstract: | High-yield variety ‘ Nanya-2’ and low-yield variety ‘ B3/74’ were used as the materials to evaluate the effects of pollen viability on initial fruit set ratio of macadamia. The results showed that ‘Nanya-2’ had high pollen viability, and it had high fruit set ratio. The dyeing rate and germination rate of ‘ Nanya-2’ pollen was 89.0% and 33.3% respectively, which was significantly higher than that of ‘B3/74’ pollen 56.7% and 8.1%. The number of pollen and germinated pollen on stigma of ‘ Nanya-2’ was significantly greater than that of ‘ B3/74’. The initial fruit set ratio of ‘Nanya-2’ was 10.9%, significantly higher than that of ‘B3/74’ 9.0%. |
