Abstract

The study was conducted in mid-hill conditions of Palampur in the Indian Western Himalayas with objective to develop agrotechniques for fast growing fuel-wood species. At 24 months after planting (MAP), the effect of fertilizers was more evident in terms of vertical growth than radial growth. The plant height showed an increasing trend with increase in doses of fertilizer. The maximum plant height was recorded in Eucalyptus hybrid followed by Populus deltoides, while Salix tetrasperma showed the poorest vertical growth (Table 4). In terms of stem diameter, Eucalyptus hybrid was the best species followed by Grevillea robusta and Trewia nudiflora (Table 5). Application of N:P₂O₅:K₂O::150:75:75 kg/ha provided thicker stem in comparison of the lower fertilizer doses. At 36 MAP, G. robusta produced significantly highest vertical growth followed by Jacaranda acutifolia and Eucalyptus hybrid, while Bauhinia variegata showed significantly highest radial growth followed by Eucalyptus and G. robusta. In all the species, excepting G. robusta, Toona ciliata and Morus alba, the lowest fertilizer dose (50:25:25 kg/ha) provided significantly highest vertical and radial growth rate, at 36 MAP. At 36 MAP, significantly highest fresh and dry biomass (oven dry) per plant was produced by Eucalyptus followed by G. robusta and Melia azedarach. The maximum dry weight (62%) was recorded in case of M. alba. At 72 MAP, the significantly highest fresh and dry weight per plant were recorded in Eucalyptus followed by G. robusta, T. ciliata and M. azedarach. Amongst the plants not treated with fertilizers, the highest fresh and dry weight was recorded in G. robusta planted at 1 m x 1 m spacing. The same species when planted closer at 1 m x 0.71 m spacing was comparable to Eucalyptus. Amongst all the test species, G. robusta had highest calorific value.

Abstract

The study was conducted to evaluate plant growth regulators (PGR) viz., IAA, IBA and NAA at three concentrations, 50, 100 and 200 mg/l, in terms of rate of sprouting in stem-cuttings and growth of the sprouted cuttings of Tylophora asthmatica, during July 2004 and 2006 in Palampur at mid hills of western Himalaya. Observations were recorded on sprouting rate, leaves per sprouted cutting, length of sprouted shoots and length of ischolar_mains. Cuttings treated with IAA showed more than 50% sprouting, which was significantly higher than that due to other treatments and untreated control. Also, IAA was statistically superior to other PGRs in terms of growth of the sprouted cuttings. In terms of sprouting rate, the lowest rate of PGRs (50 mg/l) was more effective than the higher doses. In terms of biomass production, plant spacing of 50 × 25 cm and 50 × 50 cm were statistically comparable.

Abstract

The green herbage growth (September-October to 7 January) in winter was assessed in three perennial grasses, viz., Andropogon gayanus, Pennisetum polys tachyon and Brachiaria brizantha, grown as spaced plants with 49 kg of P₂O⁵ and 74 kg of N per hectare per annum under rainfed conditions at Ranchi for 3 years (1963-65). Grasses rested from 15-30 September, (after a cut in July) yielded 40-60 q/ha of green herbage with 0.4 to 0.8 per cent nitrogen (dry wt. basis) when cut on 7 January. Andropogon gayanus showed slightly more growth than the others and its leaves were less frost burnt. The plants rested from July and cut on 7 January, except in the case of Brachiaria brizantha, did not yield more than those cut in July, September-October and January. There was not much advantage in green grass growth in winter by leaving 15 em stubbles in autumn over 7.S em stubbles.

Abstract

Asparagus racemosus is a medicinally important plant, distributed in Himalayan and sub-Himalayan region of India. The ischolar_main is used in many herbal preparations. Effect of some growth hormones and chemicals was studied on its seed germination. Concentrations of IAA (Indole-acetic acid) 100, 200 and 500 mg/l, IBA (Indole-butric acid), NAA (naphthalene acetic acid), Salicylic acid, Tanic acid with water soaking as control were used. Seed germination was st started on 21^st day of seed sowing in IBA treated seeds. Highest seed germination 89.33% and 85% were recorded in IBA, 500 and 200 mg/l, respectively. Lowest seed germination was recorded in Tanic acid 100 mg/l 50.33% and in control 43%. The maximum shoot length of 18.37 cm, 18.47 cm and 18.70 cm were recorded respectively in IBA 200, 500 mg/l and NAA 500 mg/l. While ischolar_main length 6.40 cm and 6.83 cm was recorded in IBA 200 and 500 mg/l after 30 days of seed germination. A field trial was also laid out for standardization of propagation techniques by using different FYM applications. Significantly highest fresh biomass of rhizomes 132.50 t/ha and dry biomass 15.90 t/ha was recorded with the dose of FYM 30 t/ha and minimum 8.33 t/ha in FYM 0 t/ha. Various growth parameters were also recorded in the field experiment.

Abstract

The replacement of a single missing anterior tooth with an implant-supported crown is a demanding therapy. This report describes a treatment in which an anterior maxillary implant was immediately restored with a provisional restoration. During the provisional phase, an optimal emergence profile was created by adjusting the provisional restoration. An impression was made with an individually fabricated impression post for an accurate reproduction of the established emergence profile and, finally, a screw-retained all-ceramic crown was placed. By implementing this protocol, an optimal definitive result could be achieved, together with immediate patient satisfaction.

Abstract

The traumatic loss of an eye is not just the loss of an essential sense organ. It results in life-long agony of not being like others with two eyes, which can see and admire the nature's beauty. As young patients are quite sensitive to peer pressure and for them, the greatest challenges are in the terms of identity and social acceptance, so, early rehabilitation is must in such patients. This article reports on the rehabilitation of a 13-year boy with custom ocular prosthesis for his traumatically injured left eye. The custom made ocular prosthesis fitted over the patient's left eye with ophthalmomalacia, successfully restored the patient's aesthetics and improved his social acceptance thereby, improving his quality of life.

Abstract

Recognizing the need of information-sharing and its implications, development of on-line plant databases has been advocated. The present article provides details on the development of web-enabled Bioresource Information Centre for Floral Resources of Himachal Pradesh, Western Himalaya. It is a MySql database that presently houses information on ~1500 plant species. This information pertains to distribution, life form, population, local name, taxonomy, image, use, conservation status and alien species. Twelve tables form the backbone of this repository. In website creation, the database interface has been implemented using wordpress CMS written in PHP. The designing of graphic user interface has been done using HTML, CSS, PHP, JavaScript and jquery. The site allows for basic and guided search, and is compatible with all major browsers and operating systems. It is dynamic and provides the user with an option of sharing of information.

Abstract

The effect on the UV, surface tension, conductance, density and ultrasonic velocity behavior of Sodium dodecyl sulfate (SDS) has been investigated in the presence of different fixed concentrations of 15-crown-5-ether (CE) in order to study the host-guest encapsulation, if any, and the resultant change in the apparent behavior of the inclusion complexes. The apparent and transfer properties including the apparent molal volume V_Φ,s, isentropic compressibility K _Φ,s, have been deduced from the experimental data. The infinite dilution values of V _Φ,s, and K _Φ,s, of the solvated species are also estimated by extrapolation towards infinite dilution. The resulting parameters allow the observation of concomitant reorganizations occurring in the system. Results show that in presence of CE, micellization of SDS is more favorable and there is an overall increase in compressibility of the studied systems.
