This book was released on 1970 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: S2The artificial defoliation of sugar maple (Acer saccharum Marsh.) can cause a marked decline in root food reserves, especially starch, and an increase in the levels of the reducing sugars, fructose and glucose. Defoliation can also bring on the dieback-decline syndrome in sugar maples (Parker and Houston 1968). Because drought, too, can bring on dieback symptoms, the question arose whether drought (or a combination of drought and defoliation) has the same effect as defoliation on root food reserves and reducing sugars. Two experiments designed to examine this question were conducted in 1968-69. In one, the effects of both drought and defoliation were examined; in the second, defoliation was eliminated as a variable. This paper is a report on those experiments. S3.

Download or read book Effect of Fertilization on Growth Nutrient Status and Leaf Water Potential of Sugar Maple written by Janos K. Helle and published by . This book was released on 1995 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Sugar maple trees were fertilized in June 1988 on an individual tree basis in an attempt to improve tree vigour. Fertilizers included K$ sb2$SO$ sb4$, a phosphate and base cations mix, and a commercial organic mix (Maplegro). No effect of fertilization was found on foliar nutrient concentrations and water status of trees during the 1990 growing season. This is possibly the result of dilution in tree biomass, the addition of non limiting nutrients or the experimental design. A positive effect of fertilization on growth was found for one site and, at another, fertilization was found to impair growth. Thus fertilization requirements of declining sugar maple are site specific. Soil Mg was higher around trees fertilized with Maplegro, and trees fertilized with K$ sb2$SO$ sb4$ had low leaf buffering capacities." --
