Relationship between growth and ion relation in pearl millet (Pennisetum glaucum (L.) R. Br.) at different growth stages under salt stress
March 2008
Seedlings of two pearl millet (Pennisetum glaucum (L.) R. Br.) lines were exposed to 0 (control) and 100 mol m–3 NaCl salinity. Treatments were applied fourteen days after germination. Growth of the shoot and root system and ion contents were determined at seedlings (21 days after treatment) and vegetative stage (42 days after treatment). NaCl concentration caused reduction in the...
Epiphytic organisms on the pneumatophores of the mangrove Avicennia marina: occurrence and possible function
February 2008
The nature of the epiphytism of red algae and also the occurrence and possible role of other epiphytic micro-organisms within the superficial tissues of pneumatophores of Avicennia marina (Forssk.) Vierh. were investigated. Transmission electron microscopy (TEM) studies revealed that bacteria and holdfasts of red algae were present in damaged tissue of the periderm. Culture studies indicated that...
Variation in the essential oil composition of Artemisia annua L. of different growth stages cultivated in Iran
February 2008
Variation in the quantity and quality of the essential oil of Artemisia annua L.(Asteraceae) at different developmental growth stages including pre-flowering, flowering and post-flowering, are reported. The oils were obtained by hydro distillation of the air-dried samples. The yields of oils (w/w %) in different stages were in the order of: pre-flowering (0.97%), flowering (1.23%) and flowering (0.87%)....
Molecular analysis of dicot-monocot split and relationship among major angiosperm groups
January 2008
The relationship among the major angiosperm groups are modeled based on cladistic analyses primarily using RAPD technique. Phylogenetic trees of relationship derived from molecular data confirm dicots as the ancestral class of monocots, there seems no dicot-monocot split. Dicots form an ancestral class of magnoliids and the monocot lineage was derived from one of the...
Effect of pre-sowing, temperature and light on the seed germination of Arnebia benthamii (Wall. ex G. Don): An endangered medicinal plant of Central Himalaya, India
January 2008
Arnebia benthamii is under intensive utilization because of its wide use as medicinal and aromatic plant resource. Self-propagation of this species is by both seed and vegetative propagation. In an effort to improve and promote the cultivation of this over-exploited medicinal herb, the effect of temperature and light on the germination of seeds was investigated with various presowing treatments of water...
Assessment of status and biomass of Swertia angustifolia : a high value Himalayan medicinal plant
September 2007
Studies on population assessment and biomass variation in selected populations of Swertia angustifolia were undertaken in west Himalaya. Low population density across the surveyed populations indicates poor availability of the species in study area. Species showed random distribution and higher frequency of occurrence in most of the population, which is the indicator of better potential of the species in...
Allozyme diversity in South Western Ghats populations of Terminalia paniculata Roth.(Combretaceae)
September 2007
Terminalia paniculata Roth. (Combretaceae) is a tropical tree with a large natural distribution in Western Ghats. The tree is extensively utilized in pharmaceutical, timber tannin, leather and silk industries. However, the species has been overexploited and information on its existing gene pool is currently lacking. The present work was therefore carried out using allozyme markers to assess the genetic diversity...
