Abstract

Pollen grains in seven species of Salix are studied with light Microscope and Scanning Electron Microscope. The results of LM showed that pollen grains are tricolpate and the overall shape is spherical to subprolate. In polar view, most of pollen grains were 3-lobed with convex lobes. The size of pollen was very variable. The Exine was reticulate. The characters of muri such as shape and size of lumen were varied in different species. The lumen was isodiametric or heteromorphic and the patterns were orbicular, elliptic or polygonal with rounded angle. Based on former studies the pollen grains in this study were referable to the following types: Salix alba type 6, S. issatissensis type 1, S. acmophylla, S. zygostemon and S. cinerea type 2, S. elbursensis type 5, S. excelsa type 3 and 6. Our results showed that shape and size of pollen grins are similar but the exine sculpturing is different and can be used for distinguishing the species.  In addition, the exine pattern in S. zygostemon which is a hybrid species showed that S. cinerea is the male parent of this hybrid and the female parent is S. elbursensis.

Abstract [Persian]

در این پژوهش دانه‌های گرده شش گونه از جنس Salix با استفاده از میکروسکوپ نوری و الکترونی  اسکنینگ  بررسی شدند. نتایج بررسی‌ها نشان داد که دانه‌های گرده سه شیاری بوده و شکل کلی آنها از کروی تا تقریبا مستطیلی و کشیده تغییر می‌کند. بیشتر دانه‌های گرده سه لوبه با لوب‌های محدب و اندازه دانه‌های گرده بسیار متنوع و با اگزین مشبک بود. ویژگی‌های موری مانند شکل و اندازه منفذ در گونه های مختلف متفاوت و منفذ دارای اقطار برابر یا نا برابر بود و الگوی آن از دایره‌ای، بیضوی تا چند‌ضلعی دیده می‌شد. بر اساس مطالعات قبلی دانه‌های گرده در این مطالعه در تیپ‌های مختلف زیر قرار گرفتند: Salix alba در تیپ 6، S. issatissensis در تیپ 1،S. acmophylla, S. zygostemon ،S. cinerea در تیپ 2، S. elbursensis در تیپ 5 وS. excels درتیپ 3 و 6. نتایج این پژوهش نشان داد که شکل و اندازه دانه گرده در گونه‌های مختلف مشابه بوده اما ساختار اگزین متفاوت است و می‌تواند در تشخیص گونه‌ها استفاده شود. همچنین با توجه به الگوی اگزین در گونه دورگه S. zygostemonمی‌توان S. cinereaرا والد نر و گونهS. elbursensisرا والد ماده آن تشخیص داد.
