Quick Guide to Function Of Macro And Micro Nutrients

FUNCTION OF MACRO AND MICRO NUTRIENTS 

Symptoms included unusual color, necrosis, wilting, distortions; general size and growth of leaves, petioles, buds, and stems. Also noted were changes in color of inter vainal areas, veins, bases, margins, and tips of young and old leaves. Micronutrients, often referred to as vitamins and minerals, are vital to healthy development, disease prevention, and wellbeing. With the exception of vitamin D, micronutrients are not produced in the body and must be derived from the diet.

WHAT IS MACRO AND MICRO Nutrients?

Macro The nutrients which need by plants in large quantity

Micro The nutrients which need by plants in small quantity

Function of Macro Nutrients in Temprate Fruits:

1.     Nitrogen in temparate fruits:

Nitrogen is one of the important Nutrient primarily responsible for vegetative growth of apple tree. Healthy apple tree contains 2 to 6 percent nitrogen in plant tissues. Nitrogen is a major component of chlorophyll which is essential for photosynthesis, producing sugars from water and carbon dioxide.

2.     Phosphorus in Temparate fruits:

It promotes flowering and seed production. It helps in fruit set and development. It helps in maximizing bud development. It helps in energy transfer and protein synthesis.

MACRO NUTRIENTS:

·      *   NITROGEN

·      *   PHOSPHORUS

·       *  POTASSIUM

·      *  SULPHUR

MICRO NUTRIENTS:

1.     * MEGANESE

2.     *  IRON

3.     *  BORON

4.    *   COPPER

5.    *   ZINC

6.     *  MOLYBDENUM

3.     Potassium in temparate Fruits:

Thus, It is the most important nutrient regulating the quality of fruits. Potassium is involved in many aspects of plant physiology viz., activation Gf more than 60 enzymes, aiding in photosynthesis, favouring high energy status, regulation of stomata opening etc.

4.     Magnesium in temparate fruits:

Magnesium is a key constituent of the chlorophyll molecule usually 15-20% of the tree's Mg total is found in the chloroplast. It is also involved in various biochemical functions including activating enzymes involving phosphorylation and protein synthesis.

5.     Sulphur in temprate fruits:

Sulphur is a key component of amino acids, proteins and coenzymes. Thus, lack of sulfur will inhibit protein synthesis and reduce tree growth.

6.     Calcium in temprate fruits:

Calcium activates enzymes and is essential for cell division, elongation, and fruit growth. It stabilizes and ensures permeability of the cell wall, protecting it from degradation by enzymes.

·        Function of Micro Nutrients in temprate fruits:

1.     Manganese in temprate fruits:

Manganese is involved in a wide range of enzyme processes including hormone synthesis. It also plays a key role in photosynthesis.

2.     Iron in temprate fruits:

Iron is required as a precursor to chlorophyll formation and in a number of important plant enzymes. Poor supply restricts photosynthesis and, as a result, reduces leaf growth and resultant fruit yield and quality.

3.     Boron in temprate fruits:

Boron is involved in cell wall formation, stabilisation and lignification, and xylem differentiation. It is needed to ensure normal development of new tissues from roots to flowers and fruit.

4.     Copper in temprate fruits:

Copper is required for chlorophyll synthesis and is a constituent of enzymes responsible for the reduction of molecular oxygen.

5.     Zinc in temprate fruits:

Zinc is important in the formation of the growth hormone auxin. Auxin is produced by shoot tips, and controls cell division, leaf and shoot growth and fruit development. Zinc is also needed by leaf cells to form the green leaf pigment chlorophyll.
