【Abstract】 This paper studied on morphological and histological structures with BTAM428?ICS-12B and F₂ individual of BTAM428×ICS-12B.The results shown that:there are difference morphological and histological structures of resistance and susceptible sample.Number stomata of resistance sample are more than that of susceptible sample.Epidermal cerifera of resistance sample is thicker than that of susceptible sample.Diameter of vascular bundle of resistance sample are smaller than that of susceptible sample.更多还原
