Abstract

Foliar anatomy of three species of Chenopodiaceae familyincludingChenopodium album, Kochia prostrata and Noaea mucronataare studied. Various anatomical characters such as stomatal densities, guard cell length for the adaxial and abaxial epidermis, type of stomata, and density of trichomeon surface, cuticle thickness, mesophyll type and variety of crystal are compared.Photosynthesis pathway is C4 in Kochia prostrata and Noaea mucronata. Foliar internal structure of species studied typically is characterized by xerophytes plants accompany by extensive central water-storage tissue which explaines Chenopodiaceae adaptation to arid and semi-arid area.

Abstract [Persian]

در طی این تحقیق آناتومی برگ در گونه‌های Kochia prostrata, Chenopodium album  و Noaea mucronata ازخانواده اسفناج مورد مطالعه قرار گرفت. تراکم روزنه درواحد سطح، و اندازه و نوع روزنه، تراکم کرک ونوع آنها مقایسه گردید. مشخصات برگ در برش عرضی بیانگر آناتومی کرانزدر دو گونه میباشد.تغییرات ساختمانی برگ از جمله بافت ذخیره کننده آب بیانگر سازش این نوع گیاهان در زیستگاههای خشک است.
