"Rice is Life" aptly describes the importance of rice in food and nutritional security, particularly for the Asian countries including India. For achieving and maintaining self sufficiency in rice, in view of ever increasing population, rice production has to be enhanced on a continual basis. The appropriate relationship between source sink and their capacity is essential to determine the yield especially in rice. In present investigation the impact of source limitation on assimilate partitioning and yield attributes to optimize the production potential and physiological basis of higher yield contributing traits in the ten genotypes. It was observed that the impact of source limitation was more pronounced in var. Dagad Desi, ARB-6, Ananda which exhibited maximum stability for grain yield. It was mainly due to the proline association with the morphological and phenological parameters as well as physiological behaviour, which ultimately raised growth rate, whereas in (control) Mahamaya and Swarna performed well. Yield was inversely related with ATR. Among cultivars, yield was directly correlated with maximum ATR under stress conditions and cultivar Swarna/ IR and Swarna maintained better translocation under stress than did the other cultivars. It clearly indicates that the defoliation of (100% leaf removal) plays significant positive contribution in balancing source sink, relatively which influenced the yield of crop and facilitating the better harvesting. Thus, it can be clearly suggested that the leaves (source) could determine the degree of plant performance and control the level of filled grain in rice.Keywords

The behaviour of the parents has direct effect on the children's psychological growth and behaviour. Parents are varied in their rearing practice and frequently unpredictable. Sometimes their interactions with children are tinged with odd combinations of beliefs such as personal prejudice, emotional regards, tradition and rule of thumb procedures. According to psychoanalytic theory social value and controls are largely interiorized on the basis of early parent-child interactions. Parents rear their children m the same way that they were reared by their parents. The reward with affection and privilege similar behaviours, punish with rejection and threats the same kind of misbehaviour for which they were chastised. This cultural drift is characteristically in the direction of the prevailing value of the general community with its gradual assimilation of new ideas, technology inventions and the shifting art. When the parents do not deal with their children m a proper way the children may develop internalizing and externalizing disorders, here we focus on externalising disorders which includes disorders with behaviour that are disruptive and often aggressive. A high level of externalizing behaviour is an obvious indication of a potential problem. Children who do not pay attention, seems exceptionally active, behave aggressively, break rules and cause significant harm to other people and their property are need special concern and proper care of their parents and caretakers. The arm of the current study was to focus on how parental counselling can be helpful in dealing with externalizing behaviour of the child. So parents need special training and counselling to handle such type of children.Keywords

Materials and Methods: The crude somatic homogenate of Gc was subjected to progressive ammonium sulfate precipitation followed by size exclusion chromatography in a Sephacryl S 100-HR column. The partially purified GST was assayed spectrophotometrically, and the corresponding enzyme activity was also recorded in polyacrylamide gel. GST isolated from the amphistome parasite was also exposed to variable changes in temperature and the pH gradient of the assay mixture.
Results: The precipitated amphistome GST molecules showed maximum activity in the sixth elution fraction. The GST subunit appeared as a single band in the reducing polyacrylamide gel electrophoresis with an apparent molecular weight of 26 kDa. The GST proteins were found to be fairly stable up to 37°C, beyond this the activity got heavily impaired. Further, the GST obtained showed a pH optima of 7.5.
Conclusion: Present findings showed that GST from Gc could be conveniently purified using gel filtration chromatography. The purified enzyme showed maximum stability and activity at 4°C.
