Cultivated sugarcane genotypes (Saccharum spp.) are derived from complex interspecific hybridisations between the species S. spontaneum and S. officinarum. To analyse this complex genome, we have investigated the potential of sugarcane microsatellite sequences as genetic markers in terms of their abundance, variability and ability to detect polymorphisms. From an enriched sugarcane genornic DNA...

Sugar maple, Acer saccharum, decline disease is incited by multiple disturbance factors when imbalanced calcium (Ca), magnesium (Mg), and manganese (Mn) act as predisposing stressors. Our objective in this study was to determine whether factors affecting sugar maple health also affect growth as estimated by basal area increment (BAI). We used 76 northern hardwood stands in northern Pennsylvania...

The absorption of Cu(2+), Zn(2+), and Mn(2+) by leaf tissue of 4-month old sugarcane plants (Saccharum officinarum L., var. H53-263) has been investigated. After the "apparent free space" fraction was desorbed, the absorption of Cu(2+), Mn(2+), and Zn(2+) yielded a curve typical of many ion uptake processes when measured as a function of the external concentration. However, only 1 absorption me...

Silvicultural restoration measures have been implemented in the northern hardwoods forests of southern Quebec, Canada, but their financial applicability is often hampered by the depleted state of the resource. To help identify sites most suited for the production of high quality timber, where the potential return on silvicultural investments should be the highest, this study assessed the impact...

Montane forests in the northeastern United States have experienced symptoms of declining vigor, such as branch dieback and increased mortality, over the last half-century. These declines have been attributed to the cumulative impacts of acid deposition, but reconstructing these declines from tree-ring records has proved difficult because of confounding factors that affect low-frequency growth p...

In a 4-year study, we investigated changes in leaf physiology, crown morphology and whole-tree biomass allocation in seedlings and saplings of shade-tolerant sugar maple (Acer saccharum Marsh.) and intermediate shade-tolerant yellow birch (Betula alleghaniensis Britt.) growing in natural understory light (0.5 to 35% of full sunlight) or in understory light reduced by 50% with shade nets to simu...

Sugarcane (Saccharum interspecific hybrids) is the main source of sugar in world. It grown more than 90 countries tropical and subtropical regions. Cultivation techniques production challenges vary by location. This document discusses character- istics sugarcane crop pests affecting its Florida, which largest producer United States

Sugarcane (Saccharum spp. hybrids) has great potential as a major feedstock for biofuel production worldwide. It is considered among the best options for producing biofuels today due to an exceptional biomass production capacity, high carbohydrate (sugar + fiber) content, and a favorable energy input/output ratio. To maximize the conversion of sugarcane biomass into biofuels, it is imperative t...

The research of silica gel manufacturing from cane pulp cinders (Saccharum Officinarum) and the application for Cu (II) ion adsorption has been done. done by some variaties, such as pH, concentration, contact time. result shows optimum pH was 8, concentration 8 ppm, time 75 minutes. perecentage recovery 90,28%, effectivity can be applicated ion.
