Title : SOME FEATURES OF Pinus pumila (Pall.) Reg. AND Pinus armandii Franch. SEED FORMATION IN THE CONDITIONS OF INTRODUCTION
Abstract : Female cone structure in two species - Pinus pumila (Pall.) Reg. and Pinus armandii Franch. in the conditions of introduction are presented in this paper. It has been demonstrated that number of scales and fertile/sterile scales index are similar to those in their native areas. At the beginning of the second year development (February) female gametophytes in both species were at free-nuclear stage and only in some P. armandii ovules alveolar stage was noticed. It was found out that the main reason for ovules` abortion is lack of pollination. However, ovules` abortion was also noticed at the second year and its reasons need to be studied in details.
