Abstract

Resin yield increases as the diameter increases upto 45 cm and then it decreases. Based on the model, optimum diameter of trees where yield will be maximum is observed to be 45 cm. This model will be used for forecasting the resin yield from the trees having diameter between 35-55 cm.

Abstract

Rooting trials using hardwood cuttings of Skimmia laureola were conducted at 1-month intervals with and without auxin treatment. It was observed that per cent callusing and ischolar_maining was higher in July and August, lower in Sepember and cuttings failed to ischolar_main in october. The results indicate that S. laureola can be vegetatively propagated by ischolar_maining cuttings, and that August is the best month and 150 ppm IAA optimum treatment for obtaining best results.

Abstract

The essential oil obtained from the leaves of newly evolved Eucalyptus hybrid FRI-5 as such and at varied dilutions viz., 1: 100, 1 : 250, 1 : 500 and 1 : 1000 bas been tested for its antimicrobial activity in-vitro against eight bacteria viz., Bacillus mycoides, B. pumilus, Escherichia coli, Proteus vulgaris, Salmonella paratyphii, Sarcina lutea, Shigella nigesta, Staphylococcus aureus and six fungi viz., Aspergillus niger, Candida albicans, Epidermophyton rubrum, Malbranchea pulchella, microsporum, gypseum, Penicillium notatum. The present investigations indicate that the Eucalyptus hybrid FRI-5 essential oil has potent antifungal as well as antibacterial efficacy being maximum when it is undiluted. The activity decreases as the dilution increase. Even at dilution of 1 : 1000) tbe oil bas been found active against all the test organisms.
