| 1. | Niche of chimonanthus praecox in northwestern hunan province 湘西北蜡梅的生态位 |
| 2. | The floral characteristics of c . nitens are less varied , and its florescence is from september to december in nanjing 而亮叶蜡梅的花部性状相对单一,在南京地区的花期从9月到12月之间。 |
| 3. | Analysis of variance for all the traits shows that there are significant differences between populations and between individuals within populations 方差分析表明:蜡梅表型性状在群体间和群体内均存在极其丰富的变异, 10个性状在群体间的差异均达显著或极显著水平。 |
| 4. | The correlations between the phenotypic traits of wintersweet and geographical and ecological factors are not significant except for latitude and annual rainfall 蜡梅表型性状与地理生态因子的相关分析表明:除纬度、年降雨量和部分性状有相关性外,其它性状和地理生态因子的相关性均不显著。 |
| 5. | Insects visited c . praecox only in the sunny days and when the highest temperature of day is higher than 10c , their visiting time is from 10 : 00 to 14 : 00 in a day , and its peak is from 12 : 00 to 13 : 00 昆虫访问蜡梅出现在最高气温超过10的晴朗天气,一天中昆虫访问时间有限,出现在10 : 00一14 :的之间, 12 : 00一13 : 。 o为昆虫活动高峰 |
| 6. | An experiment was conducted to analyse the phenotypic diversities between and within populations in terms of ten phenotypic traits using ten populations of wintersweet from the whole distribution areas in china as experimental materials 摘要以蜡梅全分布区的10个群体为试材,对10个表型性状进行比较分析,讨论群体间和群体内的表型多样性。 |
| 7. | A great number of and sweet scent of flower of c . praecox are attractants , and pollen grains and nectar of it are rewards to vistors . ( 2 ) pollen viability of different varieties of c . praecox are distinctly different ( 2 )不同品种蜡梅的花粉活力存在明显区别,室温条件下花粉活力能保持15 - 20d ,冷藏条件下( 4 2 )能保存2个月左右;柱头的可受期约5d 。 |
| 8. | The life - span of pollen is 15 to 20 days under room condition and 2 months under 4 + 2c ; the life - span of receptive stigmas is 5 days . in spite of protogyny , the meeting time of life of effective pollen and stigma of two species are respectively 2 days and 0 蜡梅与亮叶蜡梅尽管存在雌雄异熟现象,但同朵花内的雌、雄蕊的功能在时间上可遇,有效可遇期分别为2d和0 . 5d 。 |
| 9. | Link ( calycanthaceae ) , is a deciduous shrub or small tree , and an endemic plant of china . compared with other species whose florescence is earlier than its , blooming in winter , c . praecox is special in its pollination time and process 蜡梅chimonanthuspraecox ( l . ) link为蜡梅科calycanthaceae蜡梅属植物,冬季开花,与绝大多数春季至秋季开花植物相比,其传粉时间和过程具有一定的特殊性。 |
| 10. | ( 3 ) the value of p / 0 of c . praecox is 2847 . 3 + 1125 . 0 , and the total value of oci is 3 . with the above results , pollen germination rate and seed set rate , all shows that breeding system of c . praecox is facultative hybridization . the breeding system of c . nitens is similar to c . praecox , but it is higher in proportion of self - pollination than that of c . praecox ( 3 )蜡梅p / 0值为2847 . 3 1125 . 0 、 oci累计分值等于3 ,与不同处理的花粉萌发率和结实率的结果一样,都显示蜡梅繁育系统为兼性异交类型;亮叶蜡梅繁育系统同蜡梅相似,但亮叶蜡梅的自交比例相对较高 |
