Morphological Characterization of Pollen Grains of Selected Plants Causing Pollen Allergy
Abstract: AbstractThe present work pertains an attempt to investigate allergy causing pollen grains in detail at the study area. The pollen grains are tiny particles produced by the male gametophyte and were liberated into the atmosphere during pollination. When the concentration of pollen grains increases it may results various forms of allergy and also meteorological changes in the environment. The study list out 10 plants which contribute major portion of pollen …

Elucidating the Role of Temperature in Reproductivity of Plants
Abstract: Analysis on plant counter to temperature stress accumulates interest because of the expanded mindfulness with respect to an unnatural weather change. High and low temperature stresses help in setting up the slight natural division of refined plants, the restricted geographic expansion of some other financially healthfully significant species, and furthermore produce lopsided connection for certain species. All things considered, the view of plant reprisal to temperature stress falls behind other …

Cytological Studies on Paeonia emodi Wall. ex Royle: An Important Medicinal and Ornamental Plant of Kashmir Himalaya
Abstract: Paeonia emodi, an endangered species, was examined for pollen mother cell (PMC) meiosis from both wild and transplanted populations. Buds of suitable size were collected from all the three study sites and fixed in ethanol:acetic acid (1:3) for 24 h and stored in 70% alcohol under refrigeration. For slide preparation, the anthers were squashed in 2% acetocarmine. The results revealed the mean meiotic chromosome configurations of the species as 2n …
