Studies on tetraspores shedding in Padina tetrastromatica Hauck
ISBN: 9783659640285 / Angielski / Miękka / 2014 / 52 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Studies on the tetraspores shedding varied seasonally in this brown alga with peak shedding of spores in the month of February. Diurnal periodicity was observed with peak output of spores between 06:00 and 10:00 hours in all eight months of the year of it's occurrence on the coast without any shift in the peak shedding. Effect of environmental factors were studied on spore shedding and diurnal periodicity. spore shedding decreased with increase in the duration of exposure of fronds to air and max. quantity of spores were obtained under submerged conditions. The spore shedding also varied in...

Studies on the ecology of some species of sargassum
ISBN: 9783659818998 / Angielski / Miękka / 2015 / 152 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The species of Sargassum are abundant among the brown algae occurring along the Indian shores and these are the chief sources for the extraction of alginic acids, food, fodder and fertilizer.At present Ecological studies were made on three species of Sargassum growing along the Visakhapatnam and nearby localities. Data on the seasonal changes in growth collected on S.vulgare, S.ilicifolium and S.polycystum were expressed in terms of mean length of the fronds.Data obtained on the mean length of the fronds indicate that initiate the growth from March or April and attain the maximum height...

Elicitation in Andrographis paniculata using biotic elicitors
ISBN: 9783659661952 / Angielski / Miękka / 2014 / 52 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Andrographis paniculata is used to treat infections and some diseases, often being used before antibiotics were created. Andrographolide is the important secondary metabolite from this plant. To improve the production of this secondary metabolite, various elicitors are used. An 'elicitor' may be defined as a substance which, when introduced in small concentration to a living cell system, initiates or improves the biosynthesis of specific compounds. Elicitation is the induced or enhanced biosynthesis of metabolites due to addition of trace amounts of elicitors. Clone selection will be...
