Effect of methyl bromide alternatives on seedling quality, nematodes and soilborne fungi at the Blenheim and Trenton nurseries in South Carolina: 2008 to 2009

Fumigation with methyl bromide (MBr) has been the most commonly used method for producing high quality, pest-free forest tree seedlings in the southeastern United States. Of the 1 billion seedlings produced annually, approximately 95% of seedlings grown for reforestation purposes are loblolly pine. Growth and survival of seedlings after outplanting is strongly linked to high quality, pest-free forest-tree seedlings...

Simulation of water uptake and redistribution in growing media during ebb-and-flow irrigation

To optimize ebb-and-flow irrigation on concrete floors, the relative importance of substrate type, flooding depth and flooding time on water uptake of growing media in containers is important information for the grower. Describing water uptake and distribution in the container with a dynamic simulation model may overcome the disadvantages of the static parameters such as container capacity and air capacity. Water uptake...

Phylogenetic relationship among Mango (Mangifera indica L.) Landraces of Saurashtra based on DNA fingerprinting

Twenty mango cultivars (Mangifera indica Linn) collected from Gir region of Saurashtra were examined by ISSR markers. Of the 50 primers screened, 21 primers gave reproducible, polymorphic DNA amplification patterns, and were selected to construct a DNA fingerprinting map to distinguish the genotypes of mango. According to the banding patterns obtained with 21 selected primers, all cultivars tested in this study...

Effect of root zone salinity on mineral nutrition and growth of beri (Zizyphus mauritiana lam) and jaman (Eugenia jambolana lamk)

Excess of salts in the root zone of plants adversely affects their growth. It may result in loss of stands, reduced rates of plant growth, reduced yields and in severe cases, total crop failure. Salinity limits water uptake by plants by reducing the osmotic potential and thus the total potential of the soil water, additionally certain salts may be specifically toxic to plants or may upset nutritional balance, if they...

Will afforestation in temperate zones warm the Earth?

For decades, forest researchers have known that planting trees on cropland or pastures (that is, afforestation) can lower the surface albedo and that landscapes with low albedo absorb more solar radiation than more reflective surfaces. Consequently, afforestation will typically darken the Earth’s surface (when compared to grasslands or deserts). In spite of this knowledge, many believe that afforestation will cool...
