Abstract:
In order to explore the dwarfing mechanism in apple dwarfing rootstocks，the annual branches of apple dwarfing rootstocks (M27，M9，M26，MM106) and standard rootstocks (Malus robusta Rehd) were used as test materials.Tissue segregation procedure were used to segregate the morphological characteristic parameters of vessel element of differents dwarfing rootstocks were observed and measured under optical microscope and scanning electron microscope (SEM).The results indicated that the vessel element of Malus robusta Rehd and rootstocks of M series were pitted vessel;the length of vessel element of Malus robusta Rehd was significantly longer than those of rootstocks of M series;the vessel element width，pitting，membrane remnant in perforation and inclination of the end wall in M series were basically consistent with those in Malus robusta Rehd.The vessel element in apple dwarfing rootstocks were featured with small vessel element and small tail，which might be one of the reason of the dwarfing.
