In vitro propagation of Tilia platyphyllos by axillary shoot proliferation
In vitro propagation of Tilia platyphyllos Scop. has been achieved by axillary shoot proliferation and somatic embryogenesis. The influence of tree age, explant source, genotype, and phytohormones on micropropagation of juvenile and mature trees of Tilia platyphyllos has been investigated. Nodal segments and shoot tips were used as initial explants for axillary shoot proliferation. Low concentr...
متن کاملCharacterization of microsatellite loci in Tilia platyphyllos (Malvaceae) and cross-amplification in related species1
UNLABELLED PREMISE OF THE STUDY Microsatellite markers in the genus Tilia were developed to investigate the genetic variation in T. platyphyllos and its relationship with T. cordata. • METHODS AND RESULTS Fifteen microsatellite markers were developed using a microsatellite enrichment protocol. Most loci show a high level of polymorphism in two T. platyphyllos populations from France. The n...
متن کاملFlavonol glycosides found in hydroethanolic extracts from Tilia cordata, a species utilized as anxiolytics
Tilia species, among which is Tilia cordata Mill. (Tiliaceae), have been used in folk medicine as anxiolytic. The hydroethanolic extract was analyzed by using liquid chromatography with mass spectrometry HPLC-DAD-ESI-MS/MS in negative ion mode, and its chemical composition was compared to flavonoids reported as anxiolytics. The major flavonoids found were: quercetin-3,7-di-O-rhamnoside, kaempfe...
متن کاملشناسایی ترکیبهای شیمیایی عصاره گیاه نمدار (Tilia platyphyllos Scop.)
گیاه نمدار (Tilia platyphyllos) از تیره Tiliaceae دارای گلهای بسیار معطر است. گلهای گیاه نامبرده در خرداد ماه از باغ گیاه‌شناسی ملی ایران جمع‌آوری شدند. کانکریت آن با استفاده از حلال هگزان استخراج گردید. پس از جدا نمودن ناخالصی‌های موجود، عصاره مطلق با بازده 0.6% بدست آمد. تجزیه و تحلیل عصاره مطلق به کمک دستگاه GC/MS انجام گرفت که به شناسایی 19 ترکیب منجر شد که در مجموع 96% آن را تشکیل می‌دهد. ...
متن کاملMitosis in Tilia americana endosperm
The endosperm cells of the American basswood Tilia americana are favorable experimental material for investigating the birefringence of living plant spindles and anaphase movement of chromosomes. The behavior of the chromosomes in anaphase and the formation of the phragmoplast are unique. The numerous (3 n equals 123), small chromosomes move in precise, parallel rows until midanaphase when they...
