Abstract

The essential oil of newly evolved Eucalyptus/I> hybrid FRI-4 at various dilutions has been tested for its antimicrobial activity against various organisms. The pure oil has been found to be most active against all the test organisms. Even at dilution of 1 : 1000, the oil has been found to be active against all the test organisms exceptEpidermophyton floccosum.It is therefore, recommended for pharmaceutical preparations.

Abstract

The article deals with both climatic and edaphic factors affecting resin yield during various months of a tapping season. Amongst these factors evapotranspiration seems to be the most important factor. Response to these factors seems to vary with plantations raised from different seed origins. The article also attempts to give a formula for estimation of resin yield.

Abstract

The problem of anticipated shortage in the future supply of raw material for the National News Print Ltd. Nepanagar (Madhya Pradesh) has been discussed. The causes of past failures in raising plantations have been analysed and the urgent necessity for planting appropriate fast growing species to meet the demand of the Mill has been elucidated. A brief account has been given of the locality factors including climate and soil characteristics together with general moisture regime calculated for the area. A tentative classification of soils found in the tract has been presented and proper selection of sites and species fOr ensuring success has been explained. The various soil working methods, planting techniques and moisture conservtaion practices suitable for the locality have been described. Certain items of future research to achieve these objectives have also been suggested.

Abstract

Resin-yielding capacities of individual trees in each of different provenances, based on resin data recorded for 1957 to 1963, have been studied . Individual trees based on the viscosity values of their resin have been characterised. The study may help in selecting various provenances and trees for tree breeding experiment. Average viscosity values of provenances gradually increase from west to east. There seems to be an indication of presence of two broad strains of the species. The one occupying west of Chakrata and East Almora is superior to the strain found in the remaining part of the natural belt.
