Antagonistic effect of Pseudomonas spp. isolated from rhizospheric soil of Picrorhiza kurrooa (kutki) against phytopathogenic fungi

Medicinal Plants - International Journal of Phytomedicines and Related Industries (2016)

Harish Chandra Pradeep Dobhal Babita Patni A. R. Nautiyal

Plant protection is an important area which needs attention since most of the hazardous substance in the form of chemical are added into the agricultural system. Pseudomonas spp. possesses a variety of promising properties which make it better Biocontrol agent. The objectives of the present study were to isolate Pseudomonas spp. from the rhizospheric soil of a medicinal herb Picrorhiza kurrooa and their antagonistic activity against phytopathogens. Pseudomonas spp. on co inoculation with fungal pathogens inhibits the growth of all phytopathogens as compared to control. Maximum inhibition was observed against Rhizoctonia solani (63.6%) followed by Aspergillus ochraceus (63%) and Aspergillus candidus (45.4%). Pseudomonas isolate was also investigated for the effect of volatile compound and found that it inhibits the growth of all tested fungi and maximum inhibition was found against Rhizoctonia solani as compared to other plant pathogens in the present study. Our results, revealed the potentiality of Pseudomonas spp. as one of the most suitable bio-control agent in suppressing the phytopathogenic fungi.

Seed Source Determines Germination and Survivability in Saussurea obvallata (DC.) Edgew. An Endemic Herb of Indian Himalayan Region, India

Ecology Environment and Conservation (2022)

Vijay Kant Purohit Pradeep Dobhal Bhagat Singh Mengwal Jaidev Chauhan M. C. Nautiyal

The present study aims to develop conservation protocol for an endangered alpine medicinal herb Saussurea obvallata (DC.) Edgew. (Sacred lotus) through seeds and to find out the impact of seed source, seed mass and pre-treatments on germination parameters and seedling survivability. Seeds were collected from two locations of Uttarakhand i.e., Bedni (BN) and Sundardunga (SD), seed mass for each source were recorded and seeds were pre-treated with different pre-sowing treatments, i.e. GA3 (GA), KNO3 (KN) and Thiourea (TU) and kept in seed germinator (SG) (Temperature 25.0Â±2.0 Â°C and RH 80%) and Greenhouse (Temperature 21.5Â±3.30 Â°C and RH 65-80%). Seeds from SD were found 34% longer (p<0.001), 22% wider (p = 0.01) and 56% heavier (p<0.001) followed by higher germination and survivability in comparison to VN seeds. Under Seed germinator and Greenhouse the seeds from SD germinate 2 days earlier than VN seeds followed by higher germination percentage, seedling morphology and biomass. The seedling length and biomass showed significant positive correlation with seed mass. The present study suggests that healthy seeds determine higher germination and survivability, which may beneficial for designing the conservation strategies for endangered plant species.

The Proximate Chemical Composition of Barks of Some Indian Trees: Part I

Indian Forester (1970)

M. G. Karnik Kuldip Bhatia Pradeep Dobhal

The barks of the woods of Tectona grandis , Adina cordifolia , Anogeissus latifolia , Lagerstroemia parviflora , Cleistanthus callinus , Pterocarpus marsupium and Bosvellia serrata received from the Forest Utilisation Officer, Maharashtra State were analysed for tannins, cold water solubility, hot water solubility, ash, peat, ether extractives, alcohol benzene extract, pentosans,lignin and chlorite holocellulose content following standard methods. The barks were also tested qualitatively for starch and alkaloids. The results are reported in the article.

Climate-induced changes in essential oil production and terpene composition in alpine aromatic plants

Plant Stress (2024)

Pradeep Dobhal Vijay Kant Purohit Sudeep Chandra Sandeep Rawat P. Prasad

Alpine regions are biodiversity hotspots for endemic species with unique adaptations to harsh climatic conditions. These adaptations often involve specialized behaviours and metabolism including the production of secondary metabolites that protects plants from environmental stresses. This study examines the impacts of elevated CO2 (eCO2) and combined effects of elevated CO2 and temperature (eCO2+T) on two alpine aromatic herbs, namely Angelica glauca and Nardostachys jatamansi. These species were raised in open-top chambers (OTCs) and treated with elevated CO2 (600 ppm) and temperature (+2.0°C from control) during 2018 to 2020. The primary (total soluble sugar, starch, total soluble protein, amino acid, and proline contents), secondary metabolites (Phenolics, essential oil yield, and components using GC-MS), and antioxidant activities (superoxide dismutase and peroxidase) were measured. Total soluble sugar increased under eCO2, while starch content, total amino acid, and total soluble protein initially increased but later declined in response to the treatments. Proline content and antioxidant activities were higher under eCO2 and eCO2+T treatments. Total phenolic content showed both increasing (in A. glauca) and decreasing (in N. jatamansi) responses to eCO2 and eCO2+T treatments. GC-MS analysis showed decreased monoterpenes in CO2 and temperature treatments, but some sesquiterpenes showed mixed responses with both increases and decreases. These findings suggest that changes in climate can alter the composition of secondary metabolites in alpine herbs, potentially affecting their therapeutic properties and suitability for use in herbal medicine. This study provides valuable insights into the species-specific physiological responses of plants to changing climate.

Nature Interpretation Sites: A New Hope of Ex-situ Garden for Conservation and Cultivation of Economically Important RET MAPs in Higher Himalayan Regions

Jaidev Chauhan Vijay Kant Purohit Pradeep Dobhal Rajeev Ranjan Kumar Ajay Hemdan

The Himalayan mountain ecosystem offers a wide range of goods and services to humanity, benefiting both mountain dwellers and non-mountain dwellers. Mountain ecosystems play a crucial role in maintaining the hydrological cycle with feedback to regional climate and by modulating the runoffs regime, along with this mountain vegetation and soil play a significant role in lowering or mitigating risks from natural hazards. This is especially true of the great Himalaya, which serves as a rich source of hotspots of biodiversity. From a social perspective, mountains are of global significance as key destinations for tourist and recreational activities. Many alpine medicinal and aromatic plants are threatened by increased anthropogenic pressures in the Upper Himalayan region, pushing them closer to the endangered category. Aconitum heterophyllum Wall. ex Royle, an economically valuable medicinal plant native to the Himalayas, is now designated as endangered on the IUCN (2020) red list. It is one of many economically valuable medicinal plants that are now included in the RET category. Hence, a new Nature Interpretation Site was built at Baniyakund, Rudraprayag, Uttarakhand at 2460 m asl in the 2016–2020 timeframe in order to conserve related Rare, Endangered, and Threatened (RET) species. A number of RET alpine medicinal and aromatic plant species have had their germplasm preserved there, along with some other ex situ gardens.
