Abstract:

To predict the seed yield of Masson pine (Pinus massoniana Lamb.), a model via visible female cones, immature cones or mature cones in crown, a model via the most informative section of crown, and a model via cutting cones were established on the basis of the number of female cones, immature cones and mature cones after systematic sampling. Each way for modelling had its own merit, but all the three were verified easy, accurate and highly applicable.

Key words: Masson pine, Seed yield, Prediction model
