Cytogenetic Exploration of Plantago lagopus Linn. – Hare's-foot Plantain
نویسنده
چکیده
The genus Plantago of family Plantaginaceae includes about 483 species. These are small, annual or perennial herbaceous plants with various medicinal properties. The word Plantago is taken from the “planta” which means “sole of the foot”. The Plantago lagopus is a wild plant. The meiotic studies of Plantago lagopus plants revealed 12 chromosomes. The various stages of meiosis viz; Pachytene, Diplotene, Diakinesis, Metaphase and Anaphase were observed. The number of Rod Bivalents was 06, absence of Ring Bivalents & Nucleolar Chromosomes were 02 in P.lagopus. The Chiasmata Frequency was calculated at Metaphase-I (/PMC=02, /II=1.0) and at Diakinesis was (/PMC=12, /II=02). The other parameters studied included Recombination Index and Terminalization Coefficient. The Recombination Index at Diakinesis of P. lagopus was 18 and at Metaphase was 08 respectively. The Terminalization Coefficient was 0.5 in P.lagopus. The Anaphase-I was irregular in some of the PMCs. The number of late separating bivalents was 01.

Two iridoid glucosides, catalpol and aucubin, one chlorinated iridoid aglycon, rehmaglutin D were isolated from the iridoid fraction of the aerial parts of Plantago lagopus L. together with the megastigman glucoside, phlomuroside. The structures of the isolated compounds were identified by means of spectroscopic (UV, HR-ESI, 1H-NMR, 13C NMR , HMQC, HMBC, COSY) methods. This is the first report ...
متن کاملEffect of defoliation strategies on the productivity, population and morphology of plantain (Plantago lanceolata)
This trial provided information about effects of defoliation frequency, defoliation intensity and winter management (grazing or rest) on the productivity, morphology and plant population of a 3-year-old plantain (Plantago lanceolata) stand. Plant population density declined drastically over time independently of grazing management, with the greatest decrease in summer. Winter grazing had a crit...
