The thermal conduc tivities of about twenty species of trees were calculated by means of the expres sions and compared with its experimental values under the same condition. The av erage relative error is about 5%, so the calculation result is satisfactory.展开更多

The results showed that the variations of earliness in maturity, high 1000-grain weight, plant height and grain weight per spike were heritable and tended to be stable in IE3 and completely stable in IE4 The wide variation of main agronomic characteristics induced by embryo culture in vitro provided the probability of selection in wheat improvement. Some somaclonal lines with useful variations could be used directly in wheat production.展开更多
