Endogenous Levels Of Cytokinins In Ageing Cucumber Cotyledons

ABSTRACTENDOGENOUS LEVELS OF CYTOKININS IN AGEINGCUCUMBER COTYLEDONSJohn A.G. Poku, M.Sc.University of Guelph, 1974Supervisor:Professor R.A. FletcherThere are several procedures for isolating cytokinins whichinvolve a number of steps including extraction, solvent fractionationand column or paper chromatography. Various combinations of theseprocedures were tried in an attempt to isolate cytokinins from cucumbercotyledons. It was found that with this tissue it was preferable toomit a few steps ...

A Contextual Study Of Brass Band Music Within The Peki-Kpando Area Of The Volta Region Of Ghana

ABSTRACTBrass band music forms a very important part of the musical culture of the Volta Region of Ghana. As a legacy of the activities from post-colonial Ghana, brass bands generally include European brass and percussion instruments with occasional addition of local drums and other exotic instruments of the tradition as a result of indigenization. The purpose of the study is to investigate the contextual use of brass bands in funerals, festivals and state functions in the Mid-Eweland of the ...

Production Of Potato (Solanum Tuberosum L) Pre-Basic Seed Through Tissue Culture In Katibougou, Mali

ABSTRACT In Mali, the main problems limiting the productivity and production of potatoes is the nonavailability of quality seeds in adequate quantities and at affordable prices for the farmers. To meet quantity and quality requirements for potato seeds in Mali, this study proposes to undertake two experiments to improve the techniques adopted in the IPR/IFRA plant biotechnology laboratory in Mali. The evaluation of the effects of three (3) concentrations of coconut water and two (2) conc...

The Effect Of Plant Water Potential On Nitrogen Fixation Of Soybeans

THE EFFECT OF PLANT WATER POTENTLAL ON NITROGEN FIXATION OF SOYBEANS John Nene-Osom Azu, M.Sc. Supervisor: University of Guelph, 1975 Professor J.W. Tanner Field experiments at two sites, Elora and Arkell,were conducted to investigate the effect of plant water potential on the nitrogen fixation of two soybean cultivars, Vansoy and Anoka. The treatments were Vansoy and Anoka both under irrigated and non-irrigated conditions. The acetylene reduction technique was employed to estimat...

Integrated Control Of The Alfalfa Weevil, Hypera Postica (Gyllenhal) (Coleoptera: Curculionidae), In Ontario

ABSTRACTINTEGRATED CONTROL OF THE ALFALFA WEEVIL, HYPERA POSTICA(GYLLENHAL) (COLEOPTERA: CURCULIONIDAE), IN ONTARIOJohn F. Abu, Ph.D. Supervisor:University of Guelph, 1976 Professor C.R. EllisThe distribution of the established parasitoids of the alfalfaweevil, Hypera postica (Gyllenhal) in western Ontario was determinedduring 1973 to 1975. Potasson luna (Girault), a parasitoid of eggs,was found in 13 out of 17 counties surveyed, but parasitism was only0.7-17-0$. Tetrastichus incertus (Ratz.)...

ABSTRACTSarah R. Addison: A Study of Pain Behaviours in Postoperative PatientsThis study was designed to investigate behaviours whichappeared to be related to pain postoperatively of forty patientson the third and fourth day after major abdominal surgery andnurses' responses to such behaviours. The method employed toidentify and analyse these behaviours was that of participantobservation and of concurrently collecting, coding and analysingdata from the empirical situation.Two main categories ...
