“…Virus infection caused a reduction in leaf area in all three cultivars and this finding is similar to that of Adeniji et al 61 , who reported that leaf area per plant at 10 weeks after virus inoculation was higher in uninoculated plants compared to the inoculated plants for both genotypes. Telfairia mosaic virus infection caused significant reduction in leaf area of Sphenostylis stenocarpa 62 . Appiah et al 63 also reported reduction in leaf size of groundnut plants affected with the groundnut rosette disease.…”

Background and Objective: Extreme and prolonged water deficit together with the evolving nature of plant viruses has a negative impact on plant growth. This study was thus conducted to evaluate the morphological responses of okra cultivars subjected to drought and virus stress treatments. Materials and Methods: Three watering treatment blocks were set up in a split block design and plants under each block were arranged further in a Randomized Complete Block Design (RCBD). Means of plant growth measurements and yield parameters were compared using One-way Analysis of Variance (ANOVA) statistics using Minitab (version 17.0) statistical software and means of treatments were compared by Tukey mean comparison at a 5% probability level. Results: The lowest reduced plant height of 19.60±0.84 cm corresponded to Indiana plants grown under a combination of severe drought and virus treatment. The least number of leaves were reported in Indiana plants grown under a combination of severe drought and virus treatment (1.66±0.57). The highest and least stem diameter were recorded in Essoumtem control plants (9.10±0.17 mm) and Indiana plants grown under a combination of severe drought and virus treatment (2.96±0.15 mm), respectively (p = 0.00, F = 74.53). Conclusion: Results concluded that virus infection and drought stressed plants may result in impaired growth in okra cultivars used in this study.
