摘要: 为探究不同抗虫性茶树品种的叶色及挥发物差异性,对11个茶树品种进行为期2年的田间虫口密度调查,通过田间枝条室内孵化试验和室内生命参数测定试验,佐证了田间种群密度作为抗性分级标准的可靠性;并测定色差及叶片单位叶面积蜡质含量,用气相色谱-质谱联用仪(GC-MS)对未被病虫为害的一芽二叶新梢的挥发物进行检测,以期筛选不同抗虫性茶树品种间的差异物。结果显示,小贯松村叶蝉(Matsumurasca onukii)趋向于叶片色彩较暗、黄色较淡的茶树品种;茶棍蓟马(Dendrothrips minowai)趋向色彩鲜亮、饱和度高、黄色偏高的茶树品种,且茶棍蓟马更重视叶背的色泽。在挥发物方面,小贯松村叶蝉种群密度与芳樟醇的相对含量呈显著正相关,与壬醛、十二烷的相对含量呈显著负相关。茶棍蓟马的种群密度与十二烷和苯乙醇的相对含量呈显著正相关。十二烷对小贯松村叶蝉和茶棍蓟马作用不同,其含量和茶树叶片蜡质含量与种群密度间的关系呈现相同趋势,这说明同一种挥发物对不同昆虫会产生不同的趋向反应。

Abstract: In order to explore the differences in leaf color and volatiles of different insect-resistant tea cultivars, a two-year field population density survey was conducted on 11 tea cultivars. Through the indoor incubation test of field branches and the indoor life parameter determination test, the reliability of field population density as the resistance grading standard was proved. The color difference and wax content per unit leaf area of leaves were determined, and the volatiles of new shoots of one bud and two leaves that were not harmed by pests and diseases were detected by gas chromatography-mass spectrometry (GC-MS) in order to screen the differences among different insect-resistant tea cultivars. The results show that, M. onukii preferred tea cultivars with darker, lighter yellow leaves. D minowai preferred tea cultivars with brighter, more saturated colors and a higher yellow color, and D minowai placed more emphasis on the color of the leaf back. In terms of volatiles, the population densities of M. onukii were significantly and positively correlated with the relative content of linalool and negatively correlated with the relative contents of nonanal and dodecane. Population densities of D. minowai were significantly and positively correlated with the relative levels of dodecane and phenylethanol. The effects of dodecane on M. onukii and D. minowai were opposite, and the same trend was observed for the relationship between wax and population density in tea leaves, suggesting that the same volatile substance may have different reactions to different insects.
