These were raised underinducing condition to test if any morphology and structure changes. Twenty two Arabidopsismutants had various changes in morphology and anatomical structures. Twenty mutants hadlow germination rate from 10% to 60%, of which 2 had survival rates at 0% and 50%. Fivemutants occurred structure changes in the hypocotyls or stem. One of these lines, namedarris-stem, showed some unique changes: slower growth rate in comparison with the wildtype from germination to florescence; serrated margin of leaf blades, spiral rosette; morebranch in the bottom part of the stem, shorter nodes, twisted stem and branch. There were oneor several arrises along the stem. Across sections of the arrises showed one or several compactcells lumps which were round, made up of several layers of cells, looked like vascular-bundle.

The results show that B2 phase presents broad fibred shape in the forged rod, and major textures are close to {112}〈111〉and {110}〈111〉; Fibred microstructure in hot-extruded tube becomes fine and fibres have broken, at the same time,{111} orientation of many grains is close to axis direction of tube; Microstructure in cold-rolled tube consists of B2,β-Nb and4Ni2O phases, fibres has heavily broken, which restrains phase transformation during cooling and heating.

结果表明：锻棒中的B2相呈较宽的纤维状，主要的织构组分接近{112}〈111〉和{110}〈111〉；热挤压管纤维组织变细且发生碎化，多数晶粒的{111}取向接近管材的轴向；冷轧管相组成为B2、β-Nb和4Ni2O，纤维组织发生严重碎化，抑制了马氏体相变的进行，{111}〈110〉和{112}〈110〉成为主要的织构组分。
