Phosphorus Deficiency

Synopsis Title of the project Effects of match lack on carry of ions and its relation with anatomical structure in chickpea (Cicer arietinum L. cv Barichhola 5) seedlings. Introduction Phoshorus (P) is an essential element of organize nutrition, bioavailable forms are present in limited amounts in well-nigh soils (Schachtman et al. 1998; Raghothama 1999; Vance et al. 2003). It is generally considered as the plump for most limiting alimental after N for plant growth. The acid-weathered soils of tropics and sub-tropics are peculiarly prone to P- inadequacy. The World ortho orthophosphate Institute classified 65% of 500 soil samples collect from 42 countries in the tropics as acutely inferior in atomic form 15 (Koala et al. 1988). The available P in Bangladesh soils could be considered to be between low and medium. About 20.7% area was inform to be predominantly low in available P and 21.2% was medium in available P which is limiting harvest-ho me production. Plants grown in friction match deficient soil secrete thoroughgoing acid,viz. ?-ketoglutaric acid, malic acid. These acids change the pH of the soil which is a regulatory broker of ion transport. Phosphorus insufficiency decreased K+ gathering in white lupins (Shen et al. 2005), Ca2+ accumulation in plants (Sas et al. 2001) decreased submerging of phosphate in leaves of bean (Gniazdowska et al. 1999). The reports on the effect of phosphorus wish on ion transport in chickpea (Cicer arietinum L. ) is rare. Hence, chickpea is chosen as a plant material. Aims and objectives of the look wrick The proposed research work will comprise the effect of phosphorus deficiency on: 1. Accumulation and distribution of K+, Na+, Cl-, NO3- , PO43- and scrape in plant; 2. The effect of phosphorus deficiency on anatomical structure and 3. The correlation between phosphorus deficiency on ion transport with its effects on anatomical structure....If you pauperization to get a full essay, order it on our websit! e: OrderCustomPaper.com
