Five grasses of tribe Aveneae were collected from low (1100 m.a.s.l.) and highland (2300 m.a.s.l.) mountain range of Western Himalaya, Neelum Valley, to evaluate the physio-anatomical adaptations to altitudinal variability. An evidence to confirm the hypothesis that plants vegetating different altitudes must be different structurally (internal(More)
Investigation and documentation of the status of medicinal plants and associated knowledge was conducted in village Dawarian, Neelum valley AJ&K. A total of 59 plant species were used for furteen (14) different categories of diseases. The medicinal plants were economically used in treating a certain ailments, such as skin diseases (10spp., 14.49%) followed(More)
Hybridization between plant species can generate novel morphological diversity and lead to speciation at homoploid or polyploid levels. Hybrids between biennial herbs Tragopogon pratensis and T. porrifolius have been studied in experimental and natural populations for over 250 years. Here we examine their current status in natural populations in southeast(More)
BACKGROUND Accumulation of lead (Pb) in agricultural soils has become a major factor for reduced crop yields and poses serious threats to humans consuming agricultural products. The present study investigated the effects of KNO3 seed priming (0 and 0.5% KNO3 ) on growth of maize (Zea mays L.) seedlings exposed to Pb toxicity (0, 1300 and 2550 mg kg-1 Pb).(More)
Three chloroplast regions, rbcL, psbA-trnH and petA-psbJ were applied to assess the genetic relationships among six Curcuma medicinal species, which are difficult to distinguish from morphology. The Maximum Parsimony tree was conducted by Kimura 2-parameter model with MEGA 4. The genetic relationships were linked with geographical distributions among these(More)
The present work examined morphological and physiological aspects of osmoregulation in some differently adapted populations of Typha domingensis. Six populations of T. domingensis were grown in waterlogged conditions under four levels of nickel (0, 50, 100 and 1500 mg/kg of Ni). The Ni tolerance was explored on the basis of different characteristics of(More)
