To answer the question about the male cone of Pinus, we will go through the following steps:Step 1: Understand the Structure of the Male Cone The male cone of Pinus is a reproductive structure that produces male gametes. It is
was measured 12 times during the life cycle of female cones and three times towards the end of the life cycle of male cones. The net efflux of CO 2 from female cones, vegetative and male cone-bearing buds decreased exponentially with increasing quantum flux density. A simple model was ...

well as alders, hazels and hop-hornbeams – are prominent examples of monoecious broadleaf trees. They produce male and female flowers in catkin form on the same tree, the male catkins being long and prominent; fruiting catkins often have a conelike appearance, as in alders and hop-horn...
. Distance appeared to be significant in a natural stand of knobcone pine (Pinus attenuata Lemmon.) (Burczyk et al., 1996). Patterns of directionality of pollen dispersal, based on genetic marker data, have been studied only in a limited way (Shen et al., 1981; Erickson & Adams, 1989;...

The male-female cone pole is a cylindrical-conical shaped structure for installing a telecommunication antenna in those places where the visual impact of the structure must be discrete; however, the design is intended to increase the resistance force for opposing the wind as well as the impact of...
