从荷兰引进8个多花水仙（欧洲水仙N.tazetta）品种和3个中国水仙品种，观测记录和比较分析在上海崇明地区的物候期、观赏性状。结果表明：3个中国水仙的绿叶期和花期均比8个多花水仙品种长。中国水仙和Canalicculatus的花色均为花冠白色、副冠黄色，其他品种为花瓣白色、副冠橙色，花瓣黄色、副冠橙色，花瓣黄色、副冠黄色等较为艳丽的花色。所有品种的单葶花朵数均在3朵以上，花量最多的是Grand Soleil d’Or，其次为Canalicculatus。开花时花葶高度差异较大，花葶最高的为Grand Soleil d’Or，可达45cm；其次是崇明水仙、Scarlet Gem、Geranium;Canalicculatus、Pacific Coast、Minnow为微型水仙，高度为19～20cm。11个品种的花朵直径在2.5～6.5cm之间，花朵最大的是崇明水仙，其次是Cragford、Geranium、漳州水仙；花朵最小的是Canalicculatus和Minnow，花朵直径为2.5cm。通过引进和筛选优良的多花水仙品种，为丰富上海崇明岛水仙品种资源、品种改良和产业化发展提供参考依... 相似文献

The influence of flower position on the inflorescence on opening day, gender, and petal persistence was studied in three olive cultivars: Manzanillo, Mission, and Frantoio. In each cultivar, 45 inflorescences were checked every morning from flower opening to petal fall. Perfect flowers opened mainly in the beginning of the flower opening period, and staminate flowers opened later. Flower position on the inflorescence had a highly significant effect on the opening day in all cultivars. Terminal flowers and the flowers located on the primary branches opened earlier than the flowers located on the secondary branches. Flower position had also a highly significant effect on gender in Manzanillo and Mission. In Manzanillo, the secondary branches had fewer perfect flowers than the primary branches. In Mission, the secondary branches had no perfect flowers at all. Among the primary branches, the branch arising immediately next to the terminal flower had the latest flowers to open and the lowest percent of perfect flowers. In Manzanillo, perfect flowers had significantly longer petal persistence than staminate flowers. To study flower competition within the inflorescence, the distal half of 120 inflorescences, on which the flowers tend to be perfect, in three trees of Manzanillo were removed about 1 month before full bloom. There was a highly significant effect on the percent of perfect flowers that opened on the proximal half. Flower competition may be a reason for pistil abortion in flowers located on secondary branches. 相似文献

The effects of pinching and lateral bud removal (deshooting) on the development of structural shoots, the number of flowers, and the average flower stem length in young rose plants were examined, using the cultivars ‘Baccara’, ‘Sonia’ and ‘Belinda’. The effect of deshooting on flower yield varied with each cultivar. It did not affect the number of ‘Baccara’ flowers, but increased ‘Sonia’ and ‘Belinda’ flower production by 50% and 75%, respectively. Leaving flowers to bloom out on plants before the start of commercial harvest resulted in a decrease in the length of the flower stems and also reduced the beneficial effect of deshooting on flower yield. Deshooting enhanced structural shoot formation (“bottom breaks”). Pinching flower buds of structural shoots increased the number of ‘Baccara’ flowers in comparison with pruning these shoots to 40–60 cm, as in common practice. Deshooting of the structural shoots of ‘Sonia’ and ‘Belinda’ increased the number of flowers in both cultivars. 相似文献

The effect of fruit load and auxin application on the flower morphology and flower number of two aubergine cultivars was investigated under greenhouse conditions. The flowers of plants that did not set fruit showed only minor fluctuations in flower and pistil mass, and in style and anther length. However, when plants were allowed to set fruit by pollination, flower and pistil mass, and style (but not anther) length were significantly reduced during the stage of fruit growth. Style length was also reduced in flowers formed after fruit had been set parthenocarpically by the application of auxin (IAA), but there was no significant effect of IAA on style length in the absence of fruit development. The number of flowers was reduced in the presence of IAA (with or without fruit set), or following fruit set by pollination. It is suggested that fruit load and development affect flower mass and style length of aubergine whereas auxin influences the number of flowers. 相似文献
