Effects of plant growth retardants and production irradiance on morphology, post-harvest performance and anatomy of Geogenanthus undatus 'Inca'
|dc.contributor.author||Burton, Amy L|
|dc.description.abstract||Geogenanthus ‘Inca’ was grown under two photosynthetic photon flux (PPF) levels and treated with flurprimidol or ancymidol. The high PPF level resulted in significantly higher dry weights and leaf areas. Plant growth retardant (PGR) application caused significantly lower height, growth index, dry weights, root:shoot ratio and leaf areas. Following four months in a simulated interior environment, production PPF did not significantly affect most growth parameters, but PGRs significantly lowered height and growth index, with flurprimidol offering greater control than ancymidol. Anatomical observations were made on roots, root nodules, stems, and leaves of treated and untreated plants. Typical anatomy for the genus was observed in untreated plants, while treated plants showed some differences in cell and tissue diameter. In general, both PGRs resulted in reduced plant stature compared to controls, while PPF level only affected dry weights. PGR-treated plants exhibited superior post-harvest performance over untreated plants.|
