| Abstract: | Viability and germination of Pinus tabulaeformis seeds from Shanxi and Shangluo of Shaanxi were determined.The regression equation between germination rate and viability was established:(1) For Shanxi,Y=-28.941+1.276X,Correlation coefficient,r=0.994;(2) For Shangluo,Y=-23.292+1.194X,Correlation coefficient,r=0.992.which provides a scientific basis for grading seeds and timely and accurate determination of seed germination rate. |
