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 derived relating temperature and quantum flux density to the net CO 2 efflux from female cones. This model was used to estimate the ...
Male cones are not produced until some years after the first female cones, and then appear on weaker twigs in the basal region of the lower branches. This distinction in the position of male and female cones suggests that the type of cone developing on a branch system is dependent on the ...
The female and male strobili space distribution and artificial supplementary pollination of 16 clones of Pinus kesiya var langbianensis clonal seed orchard in Puwen Experimental Forest Farm of Yunnan Academy of Forestry were studied and analyzed. The results showed that the strobili were distributed in...

To solve the question regarding the characteristics of the seed of Pinus sp., we will analyze each option provided and determine the correct answer based on the known botanical features of Pinus seeds.1. Understanding Seed Characteristi
Male and female gametophyte development are described from light and transmission electron microscope preparations of ovules from first and second year Pin
Such informa- tion is also of great practical value in forestry and forest tree breeding. Male and female reproductive successes are influenced by several factors including patterns of pollen dispersal, flowering phenology and fecundity traits (Burczyk and Prat, 1997; Burczyk et al., 2004). ...

The molecular regulation of induction and development of reproductive organs is well established in angiosperms, while it is slowly accumulating in gymnosperms. Here, we conducted comparative transcriptomic profiles at different stages of male and female cone development inPinus halepensis. Our aim was ...
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
