6 extractive question-and-answer pairs built from Advances in propagation and conservation of medicinal species: A review, published by epubs.icar.org.in. Source-evidenced topics include medicinal species, propagation, conservation, vegetative propagation, plant growth regulators, rooting, seed germination, ex situ conservation. Every answer is a verbatim span of text the source prints, and each row carries the passage it sits in, its offset in that passage, the source quote, the page and the location in the document, so any row can be checked against the original. Question types in the export: 2 factual, 2 list, 1 relationship, 1 summary. 4 of the 6 pairs (66.7%) ask explanatory questions; the remaining 2 are factual or table-based questions. 100.00% of rows pass the corpus quality gate.
This dataset contains six question-and-answer pairs derived from a review on the propagation and conservation of medicinal species, published by epubs.icar.org.in. The dataset explores factors threatening medicinal plants, effective propagation methods, and the benefits of conservation practices. It highlights the role of plant growth regulators in improving propagation efficiency and seed germination. The questions include factual, list-based, relationship, and summary types, with answers sourced directly from the publication.

| Why are As many medicinal species on the verge of extinction from their natural habitats? | global climatic change, over-exploitation, anthropogenic activities, destructive harvesting, natural calamities, low seed viability, pests and diseases etc | As many medicinal species are on the verge of extinction from their natural habitats, due to global climatic change, over-exploitation, anthropogenic activities, destructive harvesting, natural calamities, low seed viability, pests and diseases etc. Hence, there is an urgent need for conservation of medicinal plants. | 93 | relationship | 0.970 | https://epubs.icar.org.in/index.php/IJAgS/article/view/174617 | As many medicinal species are on the verge of extinction from their natural habitats, due to global climatic change, over-exploitation, anthropogenic activities, destructive harvesting, natural calamities, low seed viability, pests and diseases etc. | p[0] | 0.800 | valid | |
| What is reported as the most effective practice for propagating medicinal plants? | root and stem cutting treated with different plant growth regulators | As many medicinal species are on the verge of extinction from their natural habitats, due to global climatic change, over-exploitation, anthropogenic activities, destructive harvesting, natural calamities, low seed viability, pests and diseases etc. there is an urgent need for conservation of medicinal plants. This review examined the propagation of medicinal plants through sexual (seed), vegetative (stem and root cuttings), and in vitro micro-propagation methods. Considering this the current review reported that root and stem cutting treated with different plant growth regulators is the most effective practices for propagation of medicinal plants. | 519 | summary | 0.970 | https://epubs.icar.org.in/index.php/IJAgS/article/view/174617 | Considering this the current review reported that root and stem cutting treated with different plant growth regulators is the most effective practices for propagation of medicinal plants. | p[0] | 0.700 | valid | |
| What are the benefits of promoting propagation and ex situ conservation of medicinal plants? | ensure sustainable supply, preserve genetic diversity, and support commercialisation of endangered medicinal plant species | Application of plant growth regulators has been shown to significantly improve propagation efficiency: IBA (1000 ppm) achieved 86–96% rooting and establishment, NAA and IAA (500–2000 ppm) yielded 70–90% rooting success, and GA₃ (200–1000 ppm) enhanced seed germinationto 85–97%.
