| The opening phenomenon of mature female cone in Pinus densiflora aye observed from the anatomical characteristics. The differentiation of tissue in young cone aye not complete and are going on. In the green cone as large as the adult cone, shrink-age rate of vascular strands and sclerenchyma aye 1.0¡1.5£¥ and 14.0¡16.0% respectively. The end parts of cone scales are composed of the parenchymatous cell and sclerenchyma. The middle parts in cone scales are composed of the sclerenchyma and vascular strands with the same thickness and more thin than the thickness of the end part and basal one. But thickness of sclerenchyma which compose of scale prop in the basal part of cone scale aye twice than that of vascular strand. In mature cone, the opening phenomenon of the pine cone results from the difference of shrinkage rate between vascular bundle and sclerenchyma. Especially, opening of cone scales are due to larger shrinkage rate of sclerenchyma than vascular strands in the basal part of cone scale. |
