Abstract

Analysis of growth responses of seven broad-leaved tree species under various fertiliser treatments in the nursery conditions indicate that fertiliser applications lead to a marked improvement in growth response as determined by parameters like seedling height, stem girth, as well as the widlh and length of the leaves.

Abstract

The present work has been aimed at analysing the growth response of seven indigenous tree species under the various fertiliser treatments in the field conditions. The results obtained have revealed that a marked improvement in growth responses takes place by fertiliser application. However, any recommendation as to the fertiliser and its dosage for a particular species will have to take into consideration soil characteristics of the plantation site. Keeping in view the above limitation, specific recommendations of fertiliser doses have been made for the seven species investigated.

Abstract

The results of the experiment conducted to study the effect of different levels of moisture stress indicated that the germination of spruce seed decreased as the moisture stress increased. The seed germination was 0.25% only at a moisture stress of -7.0 atm. Even the slighest moisture stress of -0.5 atm tended to decrease the seed germination' but the decrease in germination under the moisture stress of -O.5 atm was not significantly different from control.

Abstract

The dry seeds of A. lebbek were treated with 20, 40 and 80 kR of Continuous and Fractionated exposures, from Co⁶⁰ source. Of the two treatments, the higher Fractionated dose both delayed the germination and reduced the Germination Value as well as the Germination Energy Index, in comparison to the Continuous ones. As the dose rate increases, the radicle and hypocotyl length gets stunted and at 80 kR level, the radicle got highly reduced. The length of the shoot and pianule number per seedling also decreased in the same pattern. Contrastingly, the higher doses of grmma rays augmented the size of the cotyledonary leaves as well as their fresh and dry matter production. In general: (a) Fractionated dose proved more potent in retarding the vigour of the seedlings and (b) the radicle was found to be most sensi iv part of the seedling as compared to the others.

Abstract

The results of analysis of the essential oil samples from Eucalyptus tereticornis leaves collected from six forest divisions of tarai and bhabar areas in U.P. as determined by Gas-liquid chromatography have been presented in this paper. The data on component percenlages given in this paper reveal that E. tereticornis oil is generally rich in pipenes which may prove to be a good source of pinenes for induslrial utilization in the manufacture of aromatic chemicals etc.

Abstract

The floristic studies of the Uttarkashi District carried out during the year 1983-1986, reveal that the Jaads and the Khos are the major tribes of dirtrict Uttarkashi, which still use plants extensively as edibles and for the preparation of beverages. This paper describes the traditional culture of these tribes and their use of wild edibles, 124 different plant species and their edible uses are appended in a list.
