At the same time,a tension stress is applied on theγ′phase interfaces along the direction parallel to the stress axis,which results in the lattice expansion ofγ′phase to trap the Al,Ta atoms with the bigger radius.This brings out the accumulation of the solute atoms to form the N-type rafted structure.Al,Ta atoms with bigger radius diffuse to the {100} plane to form the linked bond of the heterogeneous atoms and the stable stacking mode,this is a main reason of promoting the transformation ofγ′phase into the N-type rafted structure.And the change of the strain energy density in different interfaces of the cubical-likeγ′phase is thought to be the driving force of the elements diffusion and theγ′phase directional growth during creep.

The results showed:①Anthocyanin content in mature fruits was 132170 U·g-1FW in bud mutation which was very significantly higher than that in'Ralls'(49140 U·g-1FW);②Activities of PAL and UFGT were almost the same between the two materials, but CH I and DFR activitieswere significantly high in bud mutation, which were related to the increase of anthocyanin levels in the mutant;③Bagging treatment inhibited anthocyanin synthesis of bud mutation. But anthocyanin content had significantly increased after removing the bags. Activities of CHI and UFGT increased rap idly and were much higher than those in the control after the bag removal. The increase was consistentwith the imp rovement of anthocyanin levels.
