A PRELIMINARY STUDY ON RELATIONSHIP BET WEEN SEED VIABILITY OF PINUS MASSONIANA AND GERMINATINATION INDEXES

Zheng Shenpei Zheng Yushan ( Department of Forestry Science )  
A linear relationship exists between the seed germination percent in Lab, for Pinus massoniana and the seed viability, which can be mathematically expressed as Y-1 =1.0756×-1 - 0.000826. A linear relationship also exists among the seed germination percent in nursery, seed germination percent in Lab. and viability for Pinus massoniana. The linear relationship of germination in nursery and viability is Y-1 = 1.144 X-1 + 0.0002375. The linear relationship between germination percent in nursery and germination percent in Lab. is Y-1 = 1.2497 X-1-0,00189.
