Iodine uptake and translocation in apple trees grown under protected cultivation

Quality and Quantity Loss by Aphid Infestation in Vegetables Grown under Protected Cultivation in Ladakh Region

During the hardly six months of suitable climatic window in summer season, many vegetable crops such as cabbage, cauliflower and radish are grown extensively in Ladakh region of India. These crops contribute significantly to the requirement of military and paramilitary troops in addition to the civil population inhabiting the region. In addition to growing these vegetable crops outdoor, some of...

Effects of Sulfur Application on Soil pH and Uptake of Phosphorus, Iron and Zinc in Apple Trees

The main reasons for the fixation of some elements and consequently nutrient deficiencies, especially phosphorus, iron and zinc, are high levels of calcium (calcareous soils) and soil pH. Two sulfur fertilizers (sulfur alone and sulfur + organic material + Thiobacillus spp.) with two rates (2 and 4 kg sulfur/tree) were used to decrease soil pH and availability of P, Fe and Zn in apple trees dur...

Uptake and distribution of iodine in grass and clover plants grown in solution culture.

Perennial ryegrass (S23), timothy (S48), white clover (S100) and red clover (Hungaropoly), grown in culture solutions containing 0.2 x 5.0 x M-potassium iodide, showed relatively small differences in iodine uptake. The lowest uptake occurred with timothy, the species that also produced the lowest yields of dry matter. Red clover had the lowest concentration of iodine in the shoots on all treatm...

Comparison of Methods for Detecting Voles under Apple Trees

Translocation of nitrogen in the xylem of field-grown cherry and poplar trees during remobilization.

Studies of small trees growing in pots have established that individual amino acids or amides are translocated in the xylem sap of a range of tree species following bud burst, as a consequence of nitrogen (N) remobilization from storage. This paper reports the first study of N translocation in the xylem of large, deciduous, field-grown trees during N remobilization in the spring. We applied 15N...
