Abstract

Nectary morphology of Matthiola species (Brassicaceae) in the Flora Iranica area was examined using a stereomicroscope to evaluate its systematic significance and assess infrageneric relationships. The study demonstrated that, most characters of the nectaries were constant among different populations of a given species and were taxonomically useful in the delimitation of species, and their grouping. However, nectary morphology was variable in some species. Reliable diagnostic features included; type and number of nectaries, morphology of lateral nectary, presence vs. absence, length, and distance of ramifications extending of lateral nectaries. The type and number of nectaries were useful in grouping of species. Three basic types of nectaries were present in the genus of which two lunar-shaped nectaries were predominated. The type and number of nectaries were unique in Matthiola alyssifolia and M. longipetala. The nectar structure was usually constant among individuals of different populations of polymorphic species of M. chenopodiifolia, M. revolute, and M. longipetala.

Abstract [Persian]

ریخت‌شناسی ساختار بافت نوشجای در جنس چلیپا (Matthiola) متعلق به کلمیان در محدوده فلورا ایرانیکا با استفاده از استریومیکروسکوپ به منظور درک ارزش سیستماتیکی و روابط فروجنسی آن مورد بررسی قرار گرفت. در این مطالعه، مشخص شد که بیشتر ویژگی‌های این بافت در بین جمعیت‌های یک گونه ثابت ولی بین گونه‌های مختلف این جنس متنوع هستند. ویژگی‌های قابل اتکا عبارتند بودند از: نوع و تعداد نوشجای‌ها، شکل نوشجای کناری، حضور یا فقدان، طول و فاصله ضمایم نوشجای کناری. در بین این ویژگی‌ها نوع و تعداد نوشجای در ارایه یک گروه‌بندی مفید هستند. سه نوع نوشجای در جنس مذکور دیده شد که ساختار آن‌ها در بیشتر گونه‌ها به صورت دو نوشجای قَمری شکل بود. Matthiola alyssifolia و M. longipetala از نظر نوع و تعداد نوشجای بین گونه‌ها منحصر به فرد بودند. همچنین، شکل این بافت در بین افراد جمعیت­های مختلف گونه­های چندریختی در M. longipetala، M. revoluta و M. chenopodiifolia نسبتا یکسان بود.
