A high frequency plant regeneration system was developed for the production of high yielding elite clones of Garcinia indica via direct organogenesis. A maximum number of 86.2 shoot buds per explant were induced from the mature seed segments cultured on Woody plant medium (WPM) supplemented with 2.0 mg dm -3 N 6 -benzyladenine and 1 mg dm -3 indole-3-acetic acid. Rooting was achieved on half-strength WPM medium supplemented with 3 mg dm -3 indole-3-butyric acid. Rooted plantlets were acclimatized and transferred to greenhouse for further growth. The highest survival rate of 95 % was recorded using a mixture of garden soil and sand. Histological studies clearly revealed multiple shoot formation from mature seed segments.

Biometric studies were carried out on Apis cerana indica (Fabr.) in the Nagapattinam district, Tamil Nadu, Southern India. A total of 24 colonies of A. c. indica from 13 different areas of the Nagapattinam district were sampled. Thirty two morphometric characters were statistically analysed by means of Principal Compound Analysis (PCA), Factor Analysis, Discriminant Analysis (DA) and Cluster Analysis. The morphometric features of the bees differed significantly (p < 0.05) in different areas of the district. Further the bee samples from the coastal regions of the Nagapattinam District were distinct morphologically when compared to other regions. Estudios biométricos de la abeja india Apis cerana indica(Fabr.) en el distrito de Nagapattinam, Tamil Nadu, sur de la India Resumen Se han llevado a cabo estudios biométricos en Apis cerana indica (Fabr.) en el distrito de Nagapattinam, Tamil Nadu, sur de la India. Se muestrearon un total de 24 colonias de A. c. indica en 13 áreas diferentes del distrito de Nagapattinam. Se analizaron treinta y dos caracteres morfométricos estadísticamente mediante análisis de compuestos principales (ACP), análisis factorial, análisis discriminante (AD) y análisis de clúster. Las características morfométricas de las abejas diferían significativamente (p < 0.05) en las diferentes áreas del distrito. Además, las muestras de abejas de las regiones costeras del distrito de Nagapattinam eran distintas morfológicamente, en comparación con otras regiones.
