Abstract

Leaf nutrient and biochemical properties play important role in flowering and yield parameters of a plant. Thus, a study was undertaken to estimate leaf nutrient and biochemical status at different phenological stages of bearing litchi plants (Litchi chinensis Sonn.) in variety Deshi which is one of the commercial varieties of Bihar. Altogether ten phenological and meso stages were selected as per BBCH scale of litchi to measure the level of biochemical parameters in litchi leaves from shoot emergence to harvesting of fruits. Significant variation in leaf nutrient such as content of nitrogen, phosphorus and potassium in leaf and biochemical parameters like carbohydrate, protein, phenol and chlorophyll was observed with changes in phenology. The highest amount of leaf nitrogen, phosphorus, carbohydrates (7.56%), phenol and total chlorophyll was accumulated when shoots were about 90% of final length before flowering and it gradually decreased till stage of fruit maturity. However, the maximum protein content in leaf was noted in initial stage of leaf emergence and it gradually decreased with leaf maturity and least protein content was estimated at fruit maturity stage. Specific leaf weight was increased gradually and it was maximum (0.064%) at the stage when fruit colour fully developed.

Litchi, Phenology, Leaf, nutrient, biochemical

Conclusion

On the basis of above finding it can be concluded that it may be concluded that leaf nutrient content and leaf biochemical parameters varies with phenological changes in litchi that play important role in inducing flowering and fruit set in litchi. Role of carbohydrate, nitrogen, phenol and chlorophyll has been well advocated for improving fruit set and yield as well in different crops. Thus, present study is informative pertaining to trends of change in these parameters.
