Propagation of Blueberries in Compost Amended Media

Worthey, Susan Stuart 09 May 2015 (has links)
The objective of this study was to determine the effects of propagation media containing composted material on the rooting of hardwood and softwood blueberry cuttings. The physical properties were measured at the end of the experiment. The media used were pine bark fines, composted pine bark with ammoniated nitrogen added, hardwood bark and composted chicken manure, pine bark and cotton gin waste, and control (peat moss and perlite, 1:1). All treatments resulted in a low number of rooted hardwood cuttings compared to the control. The total number of roots per cutting and alive cuttings hardwood cuttings was increased by pine bark and ammoniated nitrogen compared to the remaining treatments. The control treatment resulted in the highest number of roots per softwood cutting. None of the treatments increased the number of roots of softwood cuttings and the number of alive cuttings was increased by all treatments compared to the control.

The influence of variety and maturity on organic acids and related constituents in the highbush blueberry (Vaccinium corymbosum, L.)

Vance, Bayne Ferrier January 1964 (has links)
The possibility of evaluating the quality of blueberry fruit in chemical terms rather than by color or organoleptic methods was considered. The fruit of three varieties of commercial highbush blueberries at four stages of physiological maturity was analysed for total solids, water-insoluble solids, soluble solids, titratable acids, total acids, volatile acids, reducing sugars, total sugars and sugar-acid ratios. Differences among varieties and stages of physiological maturity were sought by use of the above measurements supplemented by a study of the individual organic acid patterns of the fruit. Meaningful differences were evident among the four stages of physiological maturity for all measurements except volatile acids and total solids. Varietal differences were evident from measurements of the pH, soluble solids, sugar-acid ratios, and a number of the individual organic acids. / Land and Food Systems, Faculty of / Graduate

Evaluación de técnicas de manejo sostenible para el control de clorosis férrica de arándanos (Vaccinium corymbosum L.) "Emerald" / Evaluation of sustainable management techniques to control iron chlorosis in blueberries (Vaccinium corymbosum L.) 'Emerald'

Valdés Medina, Bastián Cristóbal January 2017 (has links)
Memoria para optar al título profesional de Ingeniero Agrónomo / El déficit de hierro es un problema nutricional muy común en los huertos de arándano establecidos en suelos calcáreos y alcalinos, generando problemas en el crecimiento, productividad y calidad de las bayas. Frente a esta situación, las herramientas de manejo tradicionales para contrarrestar el déficit de hierro, se basan en aplicaciones reiteradas de quelatos sintéticos de hierro y/o ácidos fuertes, las cuales son de alto costo y riesgosas tanto para la salud humana como para el ambiente. En la presente investigación, se evaluaron dos técnicas de manejo sostenible: (1) asociación del cultivo con las especies gramíneas Festuca rubra o Poa pratensis y; (2) aplicación de un producto formulado a base de sangre bovina. Durante el experimento se evaluaron variables vegetativas, fisiológicas, reproductivas y de calidad de las bayas. La aplicación del formulado a base de sangre bovina ejerció un efecto positivo sobre el crecimiento vegetativo y la concentración foliar de Mn en los arándanos, sin influenciar la concentración foliar de clorofila, producción, la calidad de las bayas y el intercambio gaseoso foliar de manera positiva. Los resultados obtenidos indican que la asociación con Festuca rubra y Poa pratensis incrementaron significativamente la concentración de antocianos y fenoles de bajo peso molecular en las pieles de los arándanos. Sin embargo, tales estrategias afectaron negativamente el crecimiento vegetativo, la concentración de clorofila, las variables productivas y la concentración de minerales en las plantas, debido a la competencia por agua y nutrientes por parte de las gramíneas hacia el cultivo. Por otro lado, la asociación con gramíneas no influenció en el intercambio gaseoso foliar de los arándanos. Las estrategias sostenibles para el control del déficit de Fe sometidas a experimentación, no lograron superar la eficacia de las aplicaciones del quelato Fe-EDDHA para contrarrestar la carencia del metal en los arándanos.
