Trichome Micromorphology of Egyptian Ballota (lamiaceae) with Emphasis on Its Systematic Implication
Trichomes of 5 taxa of the genus Ballota were examined by using light and scanning electron microscopy. The indumentum shows considerable variability among different species, and therefore, affords valuable characters in delimitation of species. The characters of taxonomic interest were presence of glandular and non-glandular trichomes, number of cells (uni-, bi-, trior multi-cellular), presenc...
برگچه های 111 نمونه هرباریومی از گون های کرک دوشاخه ایران، شامل82 گونه از 13 بخش، به منظور تشخیص ترکیبات ازت دار آلیفاتیک سمی مورد بررسی قرار گرفتند. کاتابولیت های ترکیبات ازت دار، 3-نیترو 1-پروپانول و اسید3- نیتروپروپیونیک، برای احشام سمی هستند. بعلاوه این ترکیبات در طبقه بندی گیاهان نیز حائز اهمیت می باشند. وجود این نیتروتوکسین ها در 4 گونه از 82 گونه مذکور گزارش می شود.
Root hairs have sometimes provided contradictory evidence for microtubule/microfibril parallelism. This tissue was re-examined using optimized conditions for the fixation, before immunofluorescence, of root hairs. In phosphate buffer, microtubules did not enter the apical tip of radish root hairs and were clearly fragmented. However, in an osmotically adjusted microtubule-stabilizing buffer, mi...
