Chlorotic spots have been observed in plants of Clerodendrum x speciosum growing in residential gardens and parks in Piracicaba, SP, Brazil. Thin sections of diseased tissues revealed characteristic cytopathic effects of the nuclear type of the Brevipalpus (Acari: Tenuipalpidae) mite-transmitted viruses (BTrV). Brevipalpus mites, identified as B. phoenicis, infesting symptomatic C. x speciosum plants transmitted the pathogen to healthy C. x speciosum and to C. thomsonae, Gomphrena globosa, Hibiscus cannabinus, H. coccineus, H. schizopetalus, Salvia leucantha, Spathiphyllum wallasi and Tetragonia expansa causing chlorotic spots on their leaves. Mechanical inoculation using leaf extracts from infected C. x speciosum resulted in chlorotic spots on inoculated C. x speciosum, Chenopodium quinoa, C. amaranticolor, G. globosa, H. cannabinus, H. coccineus and T. expansa leaves. C. amaranticolor and C. quinoa kept at 28 - 30°C became systemically infected. The same cytopathic effects caused by the nuclear type of BTrV were seen in tissues from all infected test plants by electron microscopy. The virus was purified from systemically infected leaves of C. amaranticolor and C. quinoa. A polyclonal antiserum obtained from an immunized rabbit presented a strong reaction with the homologous antigen in ELISA tests. The results suggest that this chlorotic spot disease of C. x speciosum is caused by a new species of the nuclear type of BTrV, tentatively named Clerodendrum chlorotic spot virus (ClCSV).

Moringa oleifera Lam. is a multiple purpose tree used as human and animal food, cosmetic production and water purification. Seed priming combined with growth promoters and natural substances has been used to improve plant performance. This study aimed to verify the efficiency of seed priming using growth-promoting substances such as brassinosteroids, ascorbic acid, and moringa leaf extract on seed germination and seedling growth of Moringa oleifera. The seeds were primed with water and 24-epibrassinolide solutions (EBL 10 -10, 10 -8 and 10 -6 M), ascorbic acid (AsA 50, 100 and 150 mg.L -1) and Moringa Leaf Extract (MLE 1:30). Primed seeds with EBL 108 M improved the speed of seed germination. Seedling length and vigor increased mainly in treatments with AsA 100 mg.L -1 and MLE 1:30. The activity of the antioxidant enzyme catalase increased mainly in primed seeds with AsA. Plant height, steam base diameter, number of leaves and gas exchange parameters such as photosynthetic rate, stomatal conductance, and internal CO2 concentration increased in plants which were from primed seeds with MLE 1:30. Therefore, we recommend seed priming to improve plant growth of Moringa olefeira, mainly using MLE, a natural and ecological product. |
