Study was conducted during 2013-14 to examine the role of various dormancy breaking treatments, viz. hot water treatment, scarification, stratification, concentrated acids (H 2 SO 4 , HNO 3 and HCl), gibberellic acid, potassium nitrate, alcohol, and acetone and gamma-rays irradiation on the percentage germination, seedling growth and seed vigour. Dried seeds were incubated in the plant growth chambers for 20-28 days at constant temperature of 25±2 °C under continuous light (16 hrs) photoperiod after its treatments. Maximum percent germination 97.2% was obtained in Innula racemosa followed by Rheum webbianum (95.1%), Carum carvi (93.4%), Saussurea lappa (90.01%) and Bunium persicum (81.4%) when seeds were pretreated with acid (H 2 SO 4 for 5 minutes). According to results obtained in present study, all studied species found best germination with H 2 SO 4 for 5 minutes in duration of 30 days. The seedlings derived from seeds exposed to the various treatments performed well when grown in a green house. Maximum length of seedlings were found in 24.3 cm in S. lappa followed by R. webbianum (23.8 cm) and C. carvi (22.2 cm) when seeds were pretreated with H 2 SO 4 for 5 minutes, on the other side B. persicum (19.4cm) in hot water treatment at 80°C for 20 minutes and I. racemosa (17.4 cm) in 0.2 KNO 3 for 10 minutes. Highest value of seed vigour index (2263) and lowest seed vigour index (390) was found in R. webbianum and B. persicum. The well developed seedlings were observed in 90 days and transplanted it for further developments. The data have implications for conservation and cultivation of the species studied.
In the present study a total of one hundred thirty two accession of indigenous vegetable (Atriplex hortensis L.) collected from fifteen different Trans-Himalayan geographical regions of Jammu and Kashmir, India, were morphologically characterized for 6 qualitative and 15 quantitative traits following descriptors developed by the National Bureau of Plant Genetic Resource (NBPGR), New Delhi, India, during the year 2014 -2015. Multivariate analysis, principal component analysis (PCA), multidimensional scaling (MDS) and cluster analysis were performed using morphological traits to determine whether these populations are reliably similar or diverse. The first two principal components encompass more than 60% variation among population. The results of PCA and MDS analysis were comparable to the cluster analysis, which shows considerable phenotypic variation. Study of morphological characteristics of the accessions showed considerable variations which signify rich diversity within populations from different regions of cold desert.
Different concentration i.e. 1000ppm, 3000ppm, 5000ppm of eighteen different methanolic extracts from fifteen different medicinal plant species were tested for their efficacy against Aspergillus niger and Aspergillus flavus. The plants selected were Codonopsis clematidea,
Jatropha gossypiifolia L. broadly addressed as bellyache bush, refers to therapeutic plant utilized all through Asian countries. A few human and veterinary utilizations in conventional medication are portrayed for various specifics and arrangements dependent on aforementioned plant. This paper give a cutting-edge review of conventional uses, pharmacology, and toxicology of J. gossypiifolia species, taking into account examination of its therapeutic worth and potential application in integral and elective medication. Pharmacological examinations have exhibited noteworthy activity of various concentrates elements as anti-microbial, mitigating, anti-diarrheal, anti-hypertensive, and anti-cancerous specialists, among different, supporting a portion of famous employments. No clinical preliminary was distinguished to date. Moreover investigations are important to test significant society utilizations, just as to discover naive bioactive atoms with pharmacological pertinence dependent on the well-known cases. Toxicological investigations related with phytochemical examination are critical to comprehend the possible lethal impacts that could lessen its restorative worth. The current review gives bits of knowledge to future research focusing on both ethnopharmacological approval of its famous use and its investigation as another wellspring of home grown medications and additionally bioactive characteristic items.
