Increased use of heat-resistant flowers

recent years, with the hot season in advance, a variety of heat-resistant flowers began landscaping play an increasingly important role, especially in the Beijing Olympic Games, 90th anniversary celebrations and other events from July to September in the hottest summer holding period, so all flowers agents increased the introduction of heat-resistant varieties of flowers, which undoubtedly contributed to the speed of its application.



Increased use of selected breeding a new direction



Currently, a large part of china flower beds are placed for municipal projects, such as the 2008 Beijing Olympics and the 2010 Shanghai World Expo and this year’s 90th anniversary, flowers are used a lot of landscaping. Among them, the application of heat-resistant varieties to increase year by year, the industry generally believe that this will be the flowers after the application of a trend.



Flowers Beijing Hui Yuan’s day flowers flower arrangement undertaken by the Institute’s National Day in Tiananmen Square for over 20 years of history, and assumed the introduction of some Olympic flowers screening, Ding Liang’s charge that the production base, heat-resistant flowers market is very promising outdoor changeable climate with July and August high temperatures, the heat resistance of the raised flower beds a very high demand. Now, many bright colors of the flowers because of poor heat resistance, with flowers during the height of the lack of application, if the breeding company through some of the breeding methods to enhance the heat resistance of these flowers will be favored by the market. “From the days of Hui Yuan Institute construction so many years of production experience, choose the right variety is very important. Each flower has different habits, tolerance to high temperature are not the same, this is the flower’s own genes decision, and therefore should be chosen when the production and application of heat resistance of some varieties of flowers, so as to save costs, while ensuring a better visual effect. “Ding Liang said.



Now, many breeders have started to develop a more heat-resistant flower beds. Sakata Seed (Suzhou) Co., Ltd. Business Development flower head Li Yuanyuan said that with global climate warming, heat-resistant rain of flowers is a great market potential of the species, its usage has been increasing, but the real resistance hot flower types is very limited, the imbalance between supply and demand is still in the state. The breed resistance, wide adaptability of the flowers is Sakata’s primary goals, such as heat resistance, rain resistance of the superb varieties of impatiens ‘Sang times Sri Lanka’ in the international market is very popular. Syngenta (China) Investment Co., Ltd. Wang Yajun flower business manager, said Syngenta Flowers around the world now have established business relationship, after the germplasm resource sharing, there will be more new, quality traits of products enter the market.



Enhanced moisture resistance to complement perennial flowers



Heat-resistant varieties of planting time is short, fast market, many northern species can be planted outdoors, greatly reducing costs. Up before the Beijing Olympics, Beijing has increased its efforts to bring plant varieties, only before the hibiscus, okra and a few large flowers flowers bloom in summer. After the introduction, now flowering in the summer than 500 kinds of flowers. So, can flower through the cultivation techniques to improve the heat resistance of it?



Reporters get the answer almost always negative. Beijing Forestry University Technology Seed Industry Co., Ltd. flowers manager Jinwen Dong said, cultivation techniques on the impact of heat-resistant varieties of itself is not great. The first is a heat-resistant plant genes, and therefore the means or through breeding to increase their heat resistance, such as the breeding ground to move from tropical and subtropical temperate, or by means of hybrid varieties of heat to change the limit. Wang Yajun, told reporters, in many cases that can not stand the heat-resistant plants, in fact, nature is resistant to high temperature plus high humidity environment can not stand. This environment is very unfavorable for plant growth, pests and diseases likely to produce, so in the cultivation process should take the necessary ventilation. Li Yuanyuan also believes that the hot summer heat and humidity is a distinctive feature, commonly known as “sauna day”, so heat-resistant flowers in cultivation, we must also consider the resistance of the rain of flowers. Sakata’s Begonia ‘Ambassador’ series and the “Members” series, Coleus, “route” series, Petunia “Merlin” series, Summer Viola “kiss” series and zinnia “rich” series, is based on this considerations and nurtured, they are more suitable for the chinese market varieties.



Ding Liang suggested that the landscaping, to increase the application of perennial flowers, perennial flowers, because the winter is generally able to secure over-summering, so its heat resistance is good. But he also said that the general heat-resistant flowers late spring germination, plant morphology smaller, ornamental traits will decline, but the early varieties of poor heat resistance and better performance. Overall, it should be used with heat-resistant varieties and non-heat-resistant varieties to meet the various periods of the flowers, leaves and the overall visual impact of the demand.
