摘　　要：通过对‘早红98’、‘赣湘1号’、‘金栀1号’、‘金栀2号’和‘长江1号’5个栀子Gardenia jasminoides农家品种开花物候期、花部形态特征的观察及其花粉生活力的测定,对其开花性状进行比较研究。结果表明:5个栀子农家品种的开花期集中在5月中旬至6月中旬,持续21～28 d;栀子花瓣数多为6瓣,个别花朵为7瓣,花瓣数与雄蕊数严格一致,且雄蕊略长于柱头,花丝极短,花药线形;5个栀子农家品种在开花当天花粉生活力均达到50%以上,且不同农家品种间花粉生活力存在极显著差异(P<0.01)。Observations were carried out on flowering stage, flower morphology of 5 varieties of Gardenia jasminoides at orchard in Jinxi of Jiangxi province and their pollen viability was determined during May to June. The result demonstrated that flowering period of 5 varieties was from mid-May to mid-June, lasting 21-28 days. Mostly 6 petals, few 7 ones. The number of petal was consistent with the number of stamen, which was slightly longer than stigma, with very short filaments and linear anther. Pollen viability of 5 varieties reached more than 50% on the day of flowering. There were significant differences in pollen viability among different varieties.
