Phosphorus Deficiency

Synopsis Title of the project Effects of match exit 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 plant nutrition, bioavailable forms are present in limited amounts in about soils (Schachtman et al. 1998; Raghothama 1999; Vance et al. 2003). It is generally considered as the plump for most limiting nutritious after N for plant growth. The acid-weathered soils of tropics and sub-tropics are especially prone to P- inadequateness. The World ortho orthophosphate Institute classified 65% of 500 soil samples collect from 42 countries in the tropics as acutely inferior in atomic yield 15 (Koala et al. 1988). The available P in Bangladesh soils could be considered to be between low and mean(a). 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-hom e production. Plants grown in friction match deficient soil secrete positive acid,viz. ?-ketoglutaric acid, malic acid. These acids change the pH of the soil which is a regulatory portion of ion transport. Phosphorus inadequacy 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 deficiency 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 dulcify 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 necessity to g et a full essay, order it on our website: OrderCustomPaper.com
