在自然和温室条件下，我们发现与健康叶片相比，五种病害类型的叶片中的生理生化成分都显着降低。感病品种的株高、干物质、光合蒸腾速率、气孔导度和水分利用效率等生长特性显著降低。Tri-2024比耐性品种高。Tri-2025。病叶中总糖、氮、氨基酸、蛋白质、多酚和儿茶素的含量也降低。然而，感病品种的降幅比耐病品种更明显。感病品种的溃烂大小和树皮水分含量均大于耐病品种。
Under natural and greenhouse conditions we found a significant reduction in the physiological and biochemical constituents in leaves of five disease types when compared to healthy ones. The growth characteristics such as height, dry mass, photosynthetic and transpiration rates, stomatal conductance, and water use efficiency were reduced significantly more in susceptible cv. TRI-2024 than in tolerant cv. TRI-2025. Also contents of total sugars, nitrogen, amino acids, proteins, polyphenols, and catechin were reduced in diseased plant leaves. However, the reduction was more prominent in susceptible than tolerant cultivar. Canker size and barker moisture content were larger in the susceptible cultivar than in the tolerant cultivar.
