不同颜色粘虫板对切花月季上西花蓟马诱集效果 总被引：3，自引：1，他引：2
研究了7种不同颜色粘虫板在贵阳地区切花月季上对西花蓟马成虫的诱集效果。结果表明:不同颜色粘虫板对不同颜色的切花月季上西花蓟马成虫的诱集效果不同,在白色切花月季上,西花蓟马最嗜好的颜色为黄色;粉色粘虫板对粉色切花月季上的西花蓟马的诱集效果最好;在红色切花月季上,西花蓟马则最偏好蓝色。另外,对于同一种颜色的粘虫板来讲,其在不同颜色切花月季上对西花蓟马的诱集效果也有所不同。黄色粘虫板对红色和白色切花月季上的西花蓟马诱集效果差异不显著,且都明显优于粉色切花月季;粉色粘虫板在粉色切花月季上对西花蓟马的诱集效果最好;蓝色粘虫板在红色切花月季上的诱集效果明显优于粉色及白色切花月季。 相似文献

SummarySelected mature seedling plants were used as stock plants and about half of them were successfully micropropagated. There was no correlation between the ability of petiole expiants to form adventitious shoots and the capacity of these shoots to multiply. Growth and development varied between the micropropagated clones, originating from one seedling each. The colour of the flowers was always constant within a clone. Developmental time, foliage height and the numbers of shoots, leaves and flowers were influenced by the BAP concentration used in vitro. The temperature during the in vitro phase affected the development time and the height of foliage and inflorescences. Increased BAP concentration (from 0 or 0.1 mg l?1 to 1 mg H) resulted in plants with a longer development time to anthesis and more shoots, leaves and flowers. Plants raised on 5 mg l?1 BAP developed slowly, resulting in stunted growth, low foliage height, few leaves and flowers. Consequently, it is possible to use the BAP concentration in vitro to regulate the growth of the progeny crop. After transfer to soil in a growth chamber, plants grown at 10°C in vitro flowered earlier, and had lower foliage and higher inflorescences than plants grown at 21°C. This observation indicates that flowering may be promoted by low temperatures in vitro. 相似文献

Two experiments were undertaken in southern Greece during 2000–2002 in which turnip-rooted parsley was tested for its suitability for cultivation in comparison with locally grown curly-leafed and plain-leafed forms. Plants were harvested when the foliage was acceptable for marketing, rather than on completion of the vegetative cycle, hence root size was relatively small. In year 1, the foliage development of plain-leafed parsley was significantly higher than that of the other two forms, irrespective of sowing date. In year 2, both plain-leafed and curly-leafed parsley produced more foliage than turnip-rooted parsley in the early sowing (November), but not in subsequent sowings (December and February). During both years, root development was higher in turnip-rooted parsley than in curly-leafed parsley, although in the November and February sowings of year 1 the root weight of both plain-leafed and turnip-rooted forms were similar. In all three types of parsley, foliage yield fell off significantly in the spring sowing (February), and in year 1 there was a considerable decrease in root production as well. In most cultivars, foliage weight was higher when plants were grown from transplanted seedlings rather than by direct sowing, whereas the effect of sowing method on root weight was sowing date dependent. Cultivar differences in the foliage weight of direct sown and transplanted plants were reflected by differences in plant height and, in some cases, by leaf number. It is concluded that although overall turnip-rooted parsley produced rather less foliage than that plain-leafed parsley, this was compensated for by the satisfactory production of roots and therefore turnip-rooted cultivars may constitute a suitable crop for introduction to the Mediterranean region. 相似文献

The influence of temperature on breaking dormancy, and on stimulating flower initiation and development has been studied.The largest number of foliage leaves per plant developed after a dormant period of 80–120 days at a temperature of 10–15°C. The greater the number of foliage leaves, the higher the probability of formation of an inflorescence. The cooling period at 10–15°C must follow immediately after the vegetation period.Plants grown continuously at 25°C developed few or no foliage leaves after dormancy and died after 2 or 3 years. Inflorescences, developed after a dormant period above 17°C, were of poor quality. The later the cooling period began after wilting of the foliage leaves, the greater number of young inflorescences died.Bulbs stored under unfavourable conditions differentiated fewer primordia, and initiation of inflorescences, with a few exceptions, did not occur. A dormancy period at 5°C or less is fatal to the plants. 相似文献
