| Abstract: |
| The more suitable combination of concentrations of hormons and the better method for tip(0.2 mm,and 0.5 mm in length)culture of early ripening peach cultivarBeinong Zaoyan (Prunus persica L.)were screened out.The main results were as follows:Percentage of sur- vival tip is approximately two folds higher on liquid culture medium of polyurethane sponge bed than on agar culture medium as tip is 0.5 mmin;length,and more than five folds higher as tip of 0.2 mm and surcical tip grow faster and better.Plants from ... |
