Some aspects of nitrogen nutrition on selected IlexGilliam, Charles Homer 08 July 2010 (has links)
Three holly cultivars, Ilex crenata, Thunb. 'Helleri' and 'Rotundifolia' and Ilex cornuta Lindl. et Paxt. 'Burfordi' were grown in 3 liter containers at 200, 300, 400 and 500 ppm nitrogen (N). Significant correlation coefficients were found between plant growth (dry wt accumulation) and both leaf N content and soil solution nitrates, while low correlation coefficients were found between soil nitrates and plant growth. Shoot growth of 'Helleri' and 'Burfordi' was not increased by N levels higher than 300 ppm while 400 ppm N was optimal for 'Rotundifolia'.
The effects of 3N levels on tissue N fluctuations during a flush of growth on 'Helleri' were also studied. For all N levels, tissue N levels were shown to increase following the cessation of stem elongation until a level of tissue N was reached where a new flush of growth began. These N levels were approx the same for all N treatments. The time necessary to reach this level was dependent on the level of N added; 5 weeks for 300 ppm, 13 weeks for 150 ppm and 18 weeks for 50 ppm N. Once new growth began, tissue N levels began to decrease.
The response of 'Helleri' to 15 fertilizer treatments consisting of different time and lengths was studied. Fertilizer applied during a period following the cessation of stem elongation and before the next flush resulted in greater total N and shoot growth, regardless of whether it was also applied during other weeks or not. Root growth was suppressed by 3 or more fertilizer applications, regardless of the time of application. / Ph. D.

Photosynthetic rates of Ilex crenata thunb. 'helleri' during propagationDupras, Michael C. January 1983 (has links)
A series of experiments was conducted to determine the effect of light, auxin, carbohydrate levels, mineral nutrients and rooting on the net photosynthetic (Pn) rate of unrooted Ilex crenata Thunb. 'Helleri' cuttings. Optimal photosynthetic activity occurred at PAR levels of about 600 micro-Einsteins m⁻² sec⁻¹. The emergence of roots increased the Pn rate. High plant carbohydrate levels were correlated to lower Pn rates while higher Pn rates were correlated to lower CHO levels. These relationships may be indicative of source-sink interactions on the Pn rate of Helleri holly cuttings. An exogenous basal application of indolebutyric acid (IBA) contributed to an increase in cutting Pn, as was the case with the addition of mineral nutrients. / M.S.
