摘要

蔷薇科（Rosaceae）的AmelanchierMedik.包括约 30 个物种，生物活性物质含量很高。研究的目的是确定萨斯卡通浆果品种 "Krasnoyarskaya"（A. alnifolia）和品种 "Prince William"（A. canadensis）在适应期和成熟期叶片的形态解剖特征。萨斯卡通浆果叶片的特点是在所有发育阶段都有下气孔和异气孔，较少出现异气孔。研究显示，极轴平均长度和气孔赤道直径取决于栽培条件和基因型。与 A. alnifolia 相比，A. canadensis 的平均气孔面积更大、表皮更厚、栅栏状脉络膜细胞的高度更高、栅栏系数更高，这使其在各发育阶段对大气降水变化的抵抗力更强。孟加拉国植物分类学杂志》。30(2):185-193，2023 年（12 月）

Anatomical Structures of Saskatoon Berry (Amelanchier Medik.)Leaves Under Different Cultivation Conditions

AmelanchierMedik. belonging to the family Rosaceae includes about 30 species with a high content of biologically active substances. The aim of the study was to determine the morpho-anatomical features of leaves at the adaptation and ontogenesis stages of Saskatoon berry variety ‘Krasnoyarskaya’ (A. alnifolia) and variety ‘Prince William’ (A. canadensis). Saskatoon berry leaves are characterized by hypostomatic and anomocytic, less often anisocytic stomata at all stages of ontogenesis. The study revealed in the average length of the polar axis and the stomata equatorial diameter, depending on the cultivation conditions and genotype. A. canadensis had a larger average stomatal area, a thicker epidermis, a greater height of the palisade chlorenchyma cells, and a higher coefficient of palisade, which made it more resistant to changes in atmospheric precipitation, at all stages of ontogenesis, in comparison A. alnifolia.

期刊介绍： Bangladesh is a humid, subtropical country favouring luxuriant growth of microorganisms, fungi and plants from algae to angiosperms with rich diversity. She has the largest mangrove forest of the world in addition to diverse hilly and wetland habitats. More than a century back, foreign explorers endeavoured several floral expeditions, but little was done for non-vasculars and pteridophytes. In recent times, Bangladesh National Herbarium has been carrying out taxonomic research in Bangladesh along with few other national institutes (e.g. Department of Botany of public universities and Bangladesh Forest Research Institute).
