Abstract
The present investigation entitled ″Study of physiologically disordered fruits of Nagpur mandarin″ was conducted at Post harvest Technology Laboratory and Analytical Laboratory, Department of Horticulture, Dr PDKV, Akola during year 2017-18 and 2018 -19. Nagpur mandarin (Citrus reticulata Blanco) is an important commercial orange cultivar mainly grown in Vidarbha region of Maharashtra and adjoining states like Madhya Pradesh and Rajasthan. Occurrence of fruit oblongation locally called as way-bar in Nagpur mandarin fruits has been observed in Amravati district. Way-bar meaning a wasteful fruit in Marathi language it is an oblonged fruit disorder. It was found that such physiologically disordered fruits were found to be high acidity and low TSS:Acid ratio, less TSS, Less sugar content, less juice content. Length:Breadth ratio, rag content, pomace content, rind thickness and rind weight were recorded to be more in physiologically disordered fruits of Nagpur mandarin. Nutrient analysis of soil macro-nutrient and micro-nutrient was carried out and it was found that the soil have optimum level of macro-nutrient Nitrogen, Phosphorous, Potassium and micro-nutrients viz., zinc, iron, manganese and copper. Plant leaf nutrient analysis was carried out of physiologically disordered plant leaves and normal plant leaves of Nagpur mandarin and it was found that zinc and potassium in the leaves of physiologically disordered plant recorded to be less as compared to normal plant of Nagpur mandarin. It is observed that the zinc and potassium from the plant leaves were found to be negatively correlated with the fruit oblongation and rind thickness. Biological indexing for detection of greening bacterium was carried out at Pathology Laboratory, ICAR-CCRI, Nagpur. 18 samples of leaves of physiologically disordered plant were study for detection of greening bacterium and the negative results were obtained i.e. physiologically disordered plant samples were not infected by the greening bacterium.
