Abstract
Micronutrients are practically as crucial as macronutrients as they play a crucial role in metabolism and proper functioning of the tissues, to improve plant growth, yield and quality. Micronutrients basically needed in very minute amount by the plants and they can be obtained from the soil, chemical fertilizers, and other sources but deficiency of these micronutrients can cause severe malfunctioning of the plants. Fruit crops cannot be produced successfully unless the plants are properly nourished. The regulation of plant growth in fruit crops is largely dependent on the integrated supply of micronutrients and macronutrients in appropriate amounts and balances. All cellular and metabolic processes depend on micronutrients. The micronutrient requirements of different plants vary. We highlight the key roles that mineral micronutrients play in fruit production in this review.
The micronutrients that are also known as the trace elements are necessary for the regular, healthy growth and reproduction of both plants and animals. The following trace elements are necessary for plant growth: zinc (Zn), manganese (Mn), copper (Cu), iron (Fe), boron (B) is not thought to be necessary for all higher plants, despite the fact that it is known to be necessary for the bacterial fixation of atmospheric nitrogen (N) in leguminous plants. However, it has been demonstrated to benefit crops in other plant families, like the graminae (e.g., Oryzae sativa, Triticum sp. etc.) (Asher and C. J., 1991) and is considered as a “beneficial” element. Silicon (Si), sodium (Na), selenium (Se), vanadium (Va), and aluminum (Al) are additional advantageous elements that have not yet been demonstrated to be "essential" (Barker et al., 2007). The following trace elements are known to be necessary for animal health: cobalt (Cu), chromium (Cr), fluorine (F), iodine (I), Fe, Mn, Mo, Se, and zinc (Zn). Nonetheless, it is also believed that seven more components are necessary for humans (Graham et al., 1996).
