Increasing soil salinity in the agricultural fields all over the world is a matter of concern. Salinity poses a serious threat to the normal growth and development of crop plants. What adds to the concern is that all the cereal crops are sensitive to increasing soil salinity. So it is implacable to either search for salinity resistant varieties of crop(More)
A study was undertaken to evaluate the salt-tolerant attributes of Cynodon dactylon by comparing it with three varieties of the model glycophyte crop rice (Oryza sativa L.). For cross generic studies, all plants were uprooted and transferred to 0.1× Hoagland solution supplemented with 0, 10, 100, 200 and 500 mM NaCl. All plants were exposed to NaCl shock(More)

Saline extracts of 207 seed varieties belonging to 53 families were tested for haemagglutinating and haemolytic activity against the erythrocytes of eleven vertebrate species (man, monkey, rabbit, rat, goat, sheep, cow, buffalo, horse, mule and fowl). Of these, 85 seed extracts showed haemagglutinating activity and 49 seed extracts showed haemolytic(More)
The ripening and softening of fleshy fruits involves biochemical changes in the cell wall. These changes reduce cell wall strength and lead to cell separation and the formation of intercellular spaces. Calcium, a constituent of the cell wall, plays an important role in interacting with pectic acid polymers to form cross-bridges that influence cell wall(More)
Calcium, an important agent in regulating cell wall autolysis during fruit ripening, interacts with pectic acid polymers to form cross-bridges that influence cell separation. In the present study, secondary ion mass spectrometry (SIMS) was used to determine whether the cell walls of apple fruit were able to take up exogenously applied44Ca, which was(More)
Darjeeling and Sikkim Himalayas, a part of Eastern Himalayan Hotspot, is characterized by its richness of plant diversity. Herbal medicine has been one of the most popular and reliable healing practices among the different ethnic groups of this region for ages. However, the lack of documentation practice by the traditional healers has led to obscurity(More)
Comparative analyses of the responses to NaCl in Cynodon dactylon and a sensitive crop species like rice could effectively unravel the salt tolerance mechanism in the former. C. dactylon, a wild perennial chloridoid grass having a wide range of ecological distribution is generally adaptable to varying degrees of salinity stress. The role of salt exclusion(More)
