3 extractive question-and-answer pairs built from Assessing genotypic diversity in Gladiolus grandiflorus for tolerance to saline conditions, published by epubs.icar.org.in. Source-evidenced topics include gladiolus grandiflorus, saline conditions, genotypic diversity, salinity stress, abiotic stress, crop productivity, commercial cut flower, icar-indian agricultural research institute. 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: 1 factual, 1 list, 1 relationship. 2 of the 3 pairs (66.7%) ask explanatory questions; the remaining 1 are factual or table-based questions. 100.00% of rows pass the corpus quality gate.
This dataset examines the effects of salinity stress on Gladiolus grandiflorus, a sensitive commercial cut flower, through research conducted at ICAR-Indian Agricultural Research Institute. It includes three question-and-answer pairs derived from the study, focusing on growth reduction, genotype resilience, and salinity sensitivity. The study evaluated ten genotypes under varying salinity levels (0, 45, and 90 mM NaCl), highlighting differences in tolerance and physiological responses.

| Why were Growth parameters, including plant height (22.1%), leaf area (37.8%) and number of corms (22.17%) significantly reduced? | highest salinity stress level (90 mM NaCl) and it varied with the genotypes | The present study was carried out during 2022–23 and 2023–24 at ICAR-Indian Agricultural Research Institute, New Delhi to evaluate the morphological, physiological and biochemical responses of 10 gladiolus genotypes (Peter Pears, Pusa Red Valentine, Warang Pink, Pusa Srijana, Urmi, Little Fawn, Urvashi, Gulal, Pusa Suhagin and Yellow Stone) under different salinity levels (0, 45 and 90 mM NaCl). Growth parameters, including plant height (22.1%), leaf area (37.8%) and number of corms (22.17%) were significantly reduced due to highest salinity stress level (90 mM NaCl) and it varied with the genotypes. Genotypes Little Fawn and Yellow Stone exhibited superior performance, maintaining higher relative water content (86.22 and 83.75%, respectively) at 90 mM NaCl, while chlorophyll levels (declined up to 10.5% at 45 mM and 23.4% at 90 mM NaCl) compared to more salinity sensitive genotypes like Pusa Srijana (68.1% reduction in RWC and 55.8% reduction in total chlorophyll). | 531 | relationship | 0.970 | https://epubs.icar.org.in/index.php/IJAgS/article/view/164173 | Growth parameters, including plant height (22.1%), leaf area (37.8%) and number of corms (22.17%) were significantly reduced due to highest salinity stress level (90 mM NaCl) and it varied with the genotypes. | p[0] | 0.800 | valid | |
| Which two genotypes maintained higher relative water content at 90 mM NaCl? | Little Fawn and Yellow Stone | Genotypes Little Fawn and Yellow Stone exhibited superior performance, maintaining higher relative water content (86.22 and 83.75%, respectively) at 90 mM NaCl, while chlorophyll levels (declined up to 10.5% at 45 mM and 23.4% at 90 mM NaCl) compared to more salinity sensitive genotypes like Pusa Srijana (68.1% reduction in RWC and 55.8% reduction in total chlorophyll). The salinity-induced oxidative stress, indicated by increased electrolyte leakage rate (83.3% in Little Fawn and 443.7% in Pusa Srijana) and malondialdehyde content (108.1%), were notably lower in the tolerant genotypes. Principal component analysis (PCA) revealed a strong correlation between growth traits and stress bio-markers, highlighting the resilience of Little Fawn and Yellow Stone. | 10 | list | 0.820 | https://epubs.icar.org.in/index.php/IJAgS/article/view/164173 | Genotypes Little Fawn and Yellow Stone exhibited superior performance, maintaining higher relative water content (86.22 and 83.75%, respectively) at 90 mM NaCl, while chlorophyll levels (declined up to 10.5% at 45 mM and 23.4% at 90 mM NaCl) compared to more salinity sensitive genotypes like Pusa Srijana (68.1% reduction in RWC and 55.8% reduction in total chlorophyll). | ||||
| What crop is particularly sensitive to salinity stress? | gladiolus (Gladiolus grandiflorusL.) | Salinity is a major abiotic stress affecting crop productivity, particularly in commercial cut flower like gladiolus (Gladiolus grandiflorusL.), which is highly sensitive. The present study was carried out during 2022–23 and 2023–24 at ICAR-Indian Agricultural Research Institute, New Delhi to evaluate the morphological, physiological and biochemical responses of 10 gladiolus genotypes (Peter Pears, Pusa Red Valentine, Warang Pink, Pusa Srijana, Urmi, Little Fawn, Urvashi, Gulal, Pusa Suhagin and Yellow Stone) under different salinity levels (0, 45 and 90 mM NaCl).
