【摘要】：在城市化高速发展的今天,城市的绿化用地日趋紧张,这就要求我们选取既可以达到绿化美观的效果,又适宜在天津栽种的品种,从而提高城市的绿化率。对天津市具有代表性的地点进行藤本月季品种调查,结果表明人们对藤本月季还不是太熟知,应用形式单调。因此,建议天津市园林部门应加大对藤本月季引种试验,对引种品种做相应的抗性检测,现有的品种应丰富其应用形式,使藤本月季在城市园林绿化中逐渐得到更广泛应用。选取了四种常见的品种:‘大游行’(Parade)、‘御用马车’(Parkdirektor Riggers)、‘黄金庆典’(Golden Celebration)、‘藤彩虹’(Rattan Rainbow)为试材,采用盆栽试验,通过对植株的叶片等生长指标、光合特性以及生理生化特性等方面进行研究,初步评价四种藤本月季是否适宜在天津栽种,了解其耐盐性和耐旱性,结果表明:在盐胁迫处理下,4种藤本月季的可溶性糖含量、可溶性蛋白含量、脯氨酸含量、丙二醛含量、超氧化物歧化酶、过氧化物酶活性基本均表现出上升的趋势,,这些测定指标的变化趋势是上升的,叶面积、叶片厚度、色素、光合指标、根系活力则表现出下降的趋势,其中‘大游行’变化的幅度最小,‘藤彩虹’的变化幅度最大;就CAT而言,‘大游行’呈现出先下降后上升的趋势,‘御用马车’、‘黄金庆典’、‘藤彩虹’均呈现出先上升后下降的趋势。在不同程度的盐胁迫处理下,不同藤本月季品种的各种指标表现出的变化规律具有一定差异,可能是由于不同品种的藤本月季应对盐胁迫的机制不同。根据隶属函数分析结果并结合四种藤本月季植株形态的表现,4种藤本月季的耐盐性强弱依次为:‘大游行’、‘御用马车’、‘黄金庆典’、‘藤彩虹’。在干旱胁迫处理下,4种藤本月季的脯氨酸含量、可溶性糖、过氧化物酶活性均上升,叶面积、叶片厚度、色素、光合指标、根系活力、丙二醛含量、可溶性蛋白含量则下降,类胡萝卜素含量、超氧化物化歧酶与过氧化氢酶表现不同,可能是由于不同品种的藤本月季应对干旱胁迫的机制不同,本试验中的藤本月季的耐旱机理还需进一步研究。根据隶属函数分析结果并结合4种藤本月季植株形态的表现,4种藤本月季的耐旱性强弱依次为:‘御用马车’、‘大游行’、‘藤彩虹’、‘黄金庆典’。综合不同藤本月季的耐盐性、耐旱性的分析结果并结合试验植株的实际表现,初步评价四种藤本月季的抗逆性强弱依次为:‘御用马车’、‘大游行’、‘藤彩虹’、‘黄金庆典’,由此可初步推出‘御用马车’和‘大游行’是抗性比较强的优良品种,可以尝试在天津市推广种植,增加绿化面积,达到美化环境的效果,创建美好天津,具有重要的实践意义。
[Abstract]:With the rapid development of urbanization, urban greening land is becoming more and more tense, which requires us to select varieties that can not only achieve beautiful greening but also be suitable for planting in Tianjin, so as to improve the green rate of the city.The results showed that the vine rose was not well known and the application form was monotonous.Therefore, it is suggested that Tianjin garden department should increase the experiment of introduction of Liana Rosa and test the resistance of introduced varieties. The existing varieties should enrich their application forms, so that Liana Rosa should be more widely used in urban landscaping.In this paper, four common varieties of 'Parade' Rattan Rainbow. were selected as the test material, and the growth indexes such as the leaves of the plants were tested by means of potted experiments, using the golden celebration of Golden Celebration.Rattan Rainbow.Photosynthetic characteristics and physiological and biochemical characteristics were studied to evaluate preliminarily whether four species of Liana rose were suitable for planting in Tianjin to understand their salt tolerance and drought tolerance. The results showed that the soluble sugar content of four species of Liana rose under salt stress was studied.Soluble protein content, proline content, malondialdehyde content, superoxide dismutase, peroxidase activity showed an increasing trend basically.Photosynthetic index, root activity showed a downward trend, in which the 'big march' had the smallest change range and the 'rattan rainbow' had the biggest change range, and the 'big march' showed a trend of first decreasing and then rising in CAT.The 'Golden Celebration' and 'Rattan Rainbow' all showed the trend of rising first and then decreasing.Under different degree of salt stress, the variation of the indexes of different vine rose varieties showed some differences, which may be due to the different mechanisms of different varieties of Liana rose to deal with salt stress.According to the results of membership function analysis and combined with the characteristics of plant morphology of four species of lianas, the salt tolerance of four species of vine rose in order of: 'the big parade'''the golden carriage' 'golden celebration' Rattan 'Rainbow'.Under drought stress, proline content, soluble sugar and peroxidase activity increased, leaf area, leaf thickness, pigment, photosynthetic index, root activity, malondialdehyde content and soluble protein content decreased.The difference of carotenoid content, superoxide dismutase and catalase may be due to the different mechanisms of different varieties of lianas to deal with drought stress.According to the results of membership function analysis and combining with the plant morphology of four species of lianas, the drought tolerance of four species of Liana rose was in turn the golden celebration of the 'Rhynchus mongolicus' parade.Based on the analysis results of salt tolerance and drought tolerance of different vine rose and the actual performance of the tested plants, the stress resistance of four kinds of vine rose was preliminarily evaluated in the order of: 'Royal carriage' parade.The 'Golden Celebration' and thus the preliminary introduction of the 'Royal Horse' and the 'Great Parade' are excellent varieties with relatively strong resistance. We can try to popularize planting in Tianjin, increase the area of greening, achieve the effect of beautifying the environment, and create a beautiful Tianjin.It has important practical significance.
