Education and social intelligence are interrelated since education is not a simple process of importing information, but it focuses on the development of personal and social qualities. Without the social and personal qualities man is incomplete. A truly educated person identifies himself as part of the society in which he lives, and makes good relations with others. Therefore, the nurturing process of social intelligence leads the academic success of the individuals. The study was carried out by Normative Survey Method under simple random sampling technique. The samples are drawn from the B,.Ed., Nursing and Medical Colleges located at Salem and Namakkal Districts of Tamilnadu, India. The sample consists of 377 professional college students studying final year course. Of them 152 were male and the rest 225were female. The results reveal that, the social intelligence of the college students are in the place of ‘average’ and their academic achievement is high. The ‘social leadership’ is higher and ‘social competency’ is lower. The college students differ in academic achievement and gender do not play any role in mean difference of their academic achievement.



This study emphasizes the Locus of Control in school students and their progress in Academic Achievement in Zoology. The Locus of Control has a significant role on students’ lives, as their decisions and choices are related to their progress. Internal or external locus of control plays an important role for students to sustain the effectiveness and usefulness of learning performance. The knowledge and experience gained by the students by means of learning the content and the role of demographic factors is vital for increasing student’s performance. In this perspective, this study was carried out by Normative Survey Method. The samples were drawn from Salem Educational District under simple random sampling technique. The sample consists of 324 higher secondary studying students in the second year. Of them 117 were male and the rest 207 were female. The results reveal that the higher secondary students are high in overall locus of control and internal locus of control and above average in ‘academic achievement in zoology. They do not differ in ‘overall locus of control, internal and external locus of control and academic achievement in zoology’ with respect to gender and locality of the school. The students are possessing high relationship between the internal LOC and AAZ.

Effect of cadmium contaminated soil on germination and seedling growth of Jatropha curcas. (Linn.)

A pot culture experiment, conducted Jatropha curcas. (L.) to germination and seedling growth the metal cadmium was added in the form of cadmium chloride.

In the studies from the results obtained that the increase in cadmium concentration affected all the growth parameters such as germination percentage, length of root and shoot, number of leaves, fresh weight of root, shoot and leaf, vigour index and tolerance index.

Studies on the effect of mutagens on seed germination, survival and pollen sterility in M1- generation of Sesame (Sesamum indicum L.)var.TMV-3.

This study was aimed to compare the effect of physical and chemical mutagens, namely gamma rays and EMS on seed germination, survival of seedlings and pollen sterility of sesame genotype TMV3. The seeds of sesame variety TMV3 were subjected to different doses of gamma rays such as 10, 20, 30, 40, 50, 60, 70, 80, 90, 100KR and various concentrations of EMS like 0.2, 0.4, 0.6, 0.8, 1.0, 1.2, 1.4, 1.6, 1.8 and 2.0mM. Seed germination test was carried out in laboratory to find out the LD50 values of Gamma rays and EMS and they were 50KR for gamma rays and 1.0mM for EMS. Based on the LD50 values, the following doses and concentrations were chosen to treat the seeds and conduct the field experiments. For Gamma rays, they were 30, 40, 50, 60 and 70KR and for EMS they were 0.6, 0.8, 1.0, 1.2 and 1.4mM and for Combined treatments they were 30KR+0.6mM, 40KR+0.8mM, 50KR+1.0mM, 60KR+1.2mM and 70KR+1.4mM. The effect of mutagens was measured for quantitative characters like seed germination, seedlings survival, seedlings height and pollen sterility and calculations were made. The results indicated that the seed germination, seedling survival and seedling height were decreased with increasing doses or concentrations of mutagens when compared to control. But in case of pollen sterility, it was increased with increasing concentrations of mutagens when compared to control. In combined treatments, plants showed high percentage of pollen sterility when compared to individual treatments and some plants showed complete sterile at 70KR + 1.4mM treatment.

Study was carried out to assess the hypoglycaemic effect of supplementing palm sugar daily for the period of thirteen days and the long- term effect of palm sugar on twelve NIDDM subjects. The effects of withdrawal of palm sugar in these subjects after a period of fifteen days was also assessed plasma glucose were estimated before and after supplementation and at the end of withdrawal period. Information regarding age, sex, family history of diabetes, dietary pattern and life style details was collected from the subjects using on interview schedule. When the subjects were classified on the familial incident of diabetes, 75% did not have a familial incident of diabetes, whereas, 25% had a familial history of diabetes, 16.6% of the subjects were smokers. It is seen that the mean fasting plasma glucose levels have decreased in the values when compared between the initial and the final day of supplementing palm sugar. After 15 days withdrawal period it is seen that the mean fasting plasma glucose levels have raised from 129.5 on the 31st day to 136.6 at the end of withdrawal period. In the same way the mean postprandial plasma glucose levels have raised from 200 on the 31 st day (end of the supplementation period) to 208. 75 at the end of withdrawal period. The supplementing palm sugar for 30 days have shown a glucose lowering effect and when withdrawn for 15 days the glucose levels have raised to a higher level nearer to that tested on the initial day.

Floral Biology and Seed Development of Swietenia macrophylla King

Swietenia macrophylla King – a valuable tropical timber species produce seeds in small quantity with annual variations. Despite of approximately 126-210 flowers per inflorescence, only one to two fruits develop generally. The reasons are not known. We, therefore, had undertaken a detailed study on the structure and development of flowers and fruits and pollination mechanism for the first time. Results showed that mahogany is monoecious with unisexual flowers borne on the same inflorescence in the ratio of 2 male: 1 female. The period between floral initiation and fruit maturity was 8½ months. Flower drop, heavy immature fruit fall within a fortnight after fertilization and the insect, Hypsipyla robusta infestation during early stages of development are the main causes for low seed production in mahogany
