Studies On Growth And Development Of Teleost Eggs With Special Reference To Deuterium Enriched Environments, Pyari Mohan Misra Jan 1963

Studies On Growth And Development Of Teleost Eggs With Special Reference To Deuterium Enriched Environments, Pyari Mohan Misra

Open Access Dissertations

Eggs of the brook trout, Salvelinus fontnalis (Mitchell), were hatched in dilute deuterium concentrations of 1, 3 and 9 percent without any observable abnormality. The eggs grew exponentially and showed a significant reduction in growth rate as a function of deuterium concentration. The larvae also grew exponentially and showed a significant but less regular reduction in grows in 1, 3 and 9 percent D2O. The ultimate weight of larvae developed from eggs incubated in the above concentrations of D2O eventually became the same when they were placed in hatchery water. Mortality during embryonic development increased with …

Factors Affecting Anthocyanin Synthesis And Morphogenesis In The Hypocotyl Of Impatiens Balsamina L., Allan Windsor Arnold Jan 1962

Factors Affecting Anthocyanin Synthesis And Morphogenesis In The Hypocotyl Of Impatiens Balsamina L., Allan Windsor Arnold

Open Access Dissertations

Physiological factors and conditions accompanying anthocyanin synthesis and morphogenesis in the hypocotyl of Impatiens balsamina L. were investigated with the objective of showing relationships between a biochemical process (anthocyanin synthesis) and morphogenetic events (the formation of epidermal hairs and roots, elongation of the hypocotyl, straightening of the hypocotyl arch), which may yield information on the physiological control of growth and development. The scope of the problem includes a study (1) of the hypocotyl anatomy, (2) of the effects of chemical agents on the development of anthocyanins, roots, and epidermal hairs in cultured hypocotyl segments and (3) of the photocontrol of …
