Macadamia plants at flowering stage were treated with different relative humidity.Results showedthat raising the level of relative humidity ,it improved the pollen vigor and fertility ,promoted the sugar andstarch accumulation so that it advanced the content of photosynthetic product, finally result in increased theyied and quality. The treatment also affected fruit development, the speed of fruit growth faster than that ofcontrol. The cultivars had different drought-tolerance which depend on their physiological and biochemicalcharacters. From the result, we reached a conclusion that over fivety percent of relative humidity was well suitto Macadamia growth and development.
