La enfermedad conocida como moho gris fue detectada sobre esta especie desde Julio a Agosto (2008-2009) causando muerte de inflorescencias y varas. Botrytis cinerea fue aislado consistentemente de inflorescencias. Su patogenicidad fue confirmada mediante inoculación de plantas de L. polyphyllum cultivadas en macetas en un invernáculo. Como resultado, se cita a Botrytis cinerea por primera vez como causante de moho gris sobre Lilium polyphyllum en India, cuyos síntomas son tizón de flores y varas. Esta enfermedad puede afectar seriamente a este hospedante en riesgo durante su estado reproductivo. A nuestro entender, no existe otro antecedente de B. cinerea sobre este hospedante

Ecological features and traditional knowledge of Roscoea alpina Royle a medicinal plant in Himalaya

Roscoea alpina Royle (Zingiberaceae) commonly known as Kakoli is a perennial medicinal herb endemic to the Himalayas. It is used in vitality strengthening Ayurveda groups i.e., Astavarga and Jeevaniyagana and in preparation of Ayurvedic formulations e.g., Chyavanprasha and Divya Pidantak Tail. Considering its medicinal uses, high demand and overexploitation, natural habitats were surveyed in subalpine and alpine regions of Garhwal Himalayas for population estimation and to identify elite germplasm. R. alpina frequency was recorded more than 60 % in Tungnath, Dayara, Valley of Flowers and Kedarnath populations. However, plant density and area occupied were low compared to other species of subalpine and alpine region. For threat category assessment, IUCN Red List Categories and criteria were used and conservation status was assigned, based on site to site and for entire Garhwal region of the Western Himalaya. R. alpina, based on extent of occurrence was categorized as Vulnerable and based on number of mature individuals as Endangered for the Garhwal Himalaya. Further, habitat destruction and degradation were the major threats for population reduction in the wild. Morphological variation revealed plants from Tungnath and Kedarnath may be used for future propagation and domestication efforts

Ayurveda Kayachikitsa towards the management of joint pain: a review

Joint pain is one of the very common problems amongst the elderly age population. Clinically it is characterized by shula, shotha and prasaarana-aakunchanayo pravruttischa vedana. Ayurveda described various treatment modalities for the management of joint pain such as; snehana, swedan, upanaha, lepa and herbal medicine. Kayachikitsa is branch which deal with use of ayurveda drugs for the management of various diseases. This branch also recommended use of different natural medicine for the treatment of joint pain. Guggulu (Comiphora mukul) is most common drug used in Amavata; disease of joint pain. Similarly various herbal formulation of Ashwagandha, Rasna, Sunthi, Pippali, Gokshura and Trivrut are also recommended in diseases of joint pain. Present article summarized role of herbal medicine in joint pain. Keywords: Ayurveda, Kayachikitsa, Joint Pain, Shula, Vedana.   &nbsp

A review on human exposure to indoor radon concentration and measuring techniques in Garhwal Himalaya, Uttarakhand

237-244Radioactive materials which occur naturally have widely presence in the earth’s crust and these materials are the most common sources of ionizing radiation present in an environment. Radon and its decay product contribute significant amount (more than 50%) of ionizing radiation in the atmosphere. This ionizing radiation increases the exposure of radiation to human being in the surroundings. The risk due to radon-222 and its decay products is more in poorly ventilated houses, mines and caves etc. This paper presents a review study on radon-222 and thoron-220 concentration/level done previously in the Garhwal region of Uttarakhand state. In this review paper, the various outcomes of indoor radon-222 and thoron-220 concentration measured in the Garhwal Himalaya region are mainly discussed in details

Deviation From \Lambda CDM With Cosmic Strings Networks

In this work, we consider a network of cosmic strings to explain possible deviation from \Lambda CDM behaviour. We use different observational data to constrain the model and show that a small but non zero contribution from the string network is allowed by the observational data which can result in a reasonable departure from \Lambda CDM evolution. But by calculating the Bayesian Evidence, we show that the present data still strongly favour the concordance \Lambda CDM model irrespective of the choice of the prior.Comment: 15 Pages, Latex Style, 4 eps figures, Revised Version, Accepted for publication in European Physical Journal
