“…Boron deficiency induces a longitudinal differentiation of younger leaves near the midrib in a young wheat field, and sawtooth results grow at the edge of young leaves (Dell and Robinson, 1993). During the anthesis, the first sign of a plant with B defect can be identified (Rerkasem and Jamjod, 2004).…”

Wheat (Triticum aestivum L.) is an important cereal crop that provides ample nutritious calories for humans and animals. The nutrient plays a vital role in the production of wheat. In this review, previous works were evaluated to investigate the role of nutrients, nutrient deficiency and toxicity in wheat. Both macro and micronutrients are necessary for wheat plants. Every nutrient has its own character and is involved in different metabolic processes of plant life. Nutrient deficiency and toxicity conditions inhibit normal plant growth and exhibit characteristic symptoms. For optimal growth, development, and production, plants need all the necessary nutrients in balance. A balanced application of the primary nutrients (N, P, K), secondary nutrient (S) and some other micronutrients (Zn, B) are needed to enhance wheat production. The soil tests and the demand for crop nutrients should be assessed to identify the quantity of fertilizer recommended for the crop. This study would be a valuable means to wheat growers and researchers for sustainable and higher wheat production.

“…Higher plants often contain 5-30 mg Ca g )1 DW (Mengel and Kirkby 2001) or 1-50 mg Ca g )1 DW (Marschner 1998). Dell and Robinson (1993) suggested that the CDL of Ca is 1.5-2.0 mg g )1 DW in the youngest leaves of Eucalyptus maculata Hook. Shoots of the control plants contained 5.15 mg Ca g )1 DW, but As-treated and additional-Fe 3+ plants contained smaller Ca concentrations, 3.60 and 3.90 mg Ca g )1 DW, respectively ( Table 1).…”

The effect of additional iron (Fe) on arsenic (As) induced chlorosis in barley (Hordeum vulgare L. cv. Minorimugi) was investigated. The treatments were: (1) 0 lmol) for 14 days. Arsenic and Fe 3+ were added as sodium-meta arsenite (NaAsO 2 ) and ethylenediaminetetraacetic acid-Fe 3+ , respectively. Chlorosis in fully developed young leaves was observed in the As-treated plants.The chlorophyll index and the Fe concentration decreased in shoots of the As-treated plants compared with the control plants. Arsenic reduced the concentration of phosphorus, potassium, calcium, magnesium, manganese, zinc and copper. The additional-Fe 3+ treatment increased the chlorophyll index in plants compared with the Astreated plants. Among the elements, Fe concentration and accumulation specifically increased in the shoots of additional-Fe 3+ plants compared with As-treated plants, indicating that As-induced chlorosis was Fe-chlorosis. Arsenic and Fe were mostly concentrated in the roots of the As-treated plants. Despite inducing chlorosis in the As-treated plants, phytosiderophores (PS) accumulation in the roots and release from the roots did not increase, rather PS accumulation decreased, indicating that As toxicity hindered PS production in the roots. The PS accumulation in the roots was further reduced in the additional-Fe 3+ treatment.

A glasshouse experiment was conducted to define the response of Eucalyptus maculata seedlings to the addition of nine rates of copper (Cu) to a Cu-deficient sand. Plants were harvested 128 days from sowing. Symptoms of Cu deficiency included marginal necrosis in young fully expanded leaves (YFEL), deformed leaf margins, death of lateral shoots, bleeding at nodes on the main stem and reduced lignification of xylem fibres and vessels. Plant height and the number of nodes on the main stem were unaffected. In plants supplied with 0 Cu, whole top and root fresh weights were depressed by 27% and 32% respectively. The external Cu requirement for maximum growth of E. maculata seedlings was similar to that for wheat grown in the same soil. In Cu-adequate plants, leaf Cu concentrations decreased with distance from the shoot apex. Cu levels in stems varied little with position and were similar to the YFEL. Cu concentrations in leaves and stems were depressed in Cu-deficient plants to <1.0/~g g-Z dry weight (d.w.) (roots: 1.5 #g g-l d.w.). The external Cu supply did not greatly alter the distribution of Cu within the plant. Young leaves at the shoot tip are recommended for diagnosis of Cu deficiency: critical values for shoot d.w. were about 1.5 #g Cu g-1 d.w. Lignification of wood was suppressed where Cu concentrations fell below 1.5 /lg g-l d.w.: the Bussler test for lignification would thus be a valuable indicator of Cu deficiency.
