“…Aptenia cordifolia (L. fill) and Lampranthus spectabilis (N.E.Br) belonging to Aiozaceae family, are two glabrous perennials and succulent plants (Dellagareca et al, 2007). L. spectabilis (syn: Mesembryanthemum spactabile) is commonly known as a fig marigold (Braun and Winkelmann, 2016;Park et al, 2016). Heptadecyl caffeic acid and 2-(2-hydroxyethyl)-3-methyl fumaric acid from the aerial parts of L. spectabilis, did not prove to have a significant antioxidant activity or cytotoxicity on a lung cancer cell line (Samy et al, 2018).…”

Lamperanthus spectabilis and Aptenia cordifolia (Aiozaceae) are two ornamental plants. A little information is available about their active compounds and meiosis’ process. In this study, the phenolic content, antioxidant activity, allelopathy effects and meiosis’ process of pollen mother cells of L. spectabilis and A. cordifolia were studied. The alcohol extract was used for phenol, antioxidant and allelopathy assay along with young buds for meiosis study. The stamens and petals of both plants possessed the highest phenol and antioxidant effects. All extracts of L. spectabilis and A. cordifolia had small inhibitory effects on mungbeen seed germination and seedlings growth. The allelopathy effect of both plants on barley seed germination and seedlings growth was significant especially for A. cordifolia. The count of chromosomes in meiosis revealed that the chromosome number of A. cordifolia was 2n=12 and 2n=18 for L. spetabilis. The meiosis in both plants was normal and the chromosomes were very small. Our results revealed that the extracts of all organs of both plants; specially stamens and petals, have a lot antioxidant activity. They had not allelopathic effects on seed germination’ and seedlings growth’ mungbeen and barley. Chromosome number of two plants was different but meiosis process and chromosomes size was similar. ********* In press - Online First.

The study was undertaken to identify and characterize Pythium isolates associated with root rot disease of tobacco seedlings as a first step towards developing management strategies for the pathogen. A total of 85 Pythium isolates were collected from diseased tobacco seedlings during 2015-2016 tobacco growing season. The isolates were identified to species level using sequencing of the internal transcribed spacer region. Thereafter, a subset of the isolates was tested for sensitivity to the commonly used fungicides, metalaxyl, azoxystrobin and a combination of fenamidone/propamocarbby growing isolates on Potato Dextrose Agar plates amended with the fungicides. The sequence analysis of the ITS-rDNA identified Pythium myriotylum as the dominant Pythium species associated with the root rot of tobacco seedlings in Zimbabwe. Pythium aphanidermatum and P. insidiosum were also identified albeit at lower frequencies. Phylogenetic analyses of the ITS region of the P. myriotylum isolates showed little sequence diversity giving rise to one distinct clade. The fungicide sensitivity tests showed that metalaxyl provided the best control of P. myriotylum in vitro, as compared to other fungicides. To the best of our knowledge, this is the first comprehensive study to determine and characterize Pythium species associated with root rot of tobacco in the float seedling production system in Zimbabwe.
