| 摘 要： | 本研究以六种甜樱桃砧木为试材，对其根皮率、根导管面积、根导管密度、根导管总面积／木质部面积比值、根木质部面积／横断面积比值、枝皮率、枝导管面积、枝导管平均总面积／木质部平均面积比值和枝木质部面积／横断面积比值等解剖结构进行了比较。试验结果表明不同砧木间各测定值存在较大差异，可以认为根皮率，枝导管密度、根、枝导管总面积／木质部面积比值和根、枝木质部面积／横断面面积比值可以作为预测甜樱桃矮化砧木矮化性的综合指标，为今后甜樱桃矮化砧木的选育提供依据。

| Abstract: | The shoot and root anatomic structures of 6 sweet cherry dwarf stocks were studied. The ratios of bark of root and shoot, the ratio of wood to bark of shoot, trachea area of root and shoot, the ratio of area of xylem to area of shoot section,trachea density of root and shoot were determined and compared. The testing results showed that several of those index, such as ratio of bark of root, trachea density of stem, trachea area /xylem area of stem and xylem area/transect area of root and stem, were significantly related to the growth potential of rootstocks, it provided bases for selecting and breeding sweet cherry dwarfing stocks in future. |
