the essential oil extracted from the epicarp of citrus sinensis exhibited absolute fungitoxicity against soybean’s fungus as alternaria alternate, aspergillus niger, cercospora kikuchii, chaetomium spp., cladosporium cladosporioides, curvularia lunata, fusarium roseum, macrophomina phaseolina, penicillium italicum, phomopsisspp. rhizoctonia solani, and sclerotium rolfsii. it is very difficult t...

The potential of slow phase chlorophyll fluorescence (CF) to predict the physiological status of Pelargonium propagules (seven varieties in 28 different batches) post shipment or post simulated shipment was evaluated. The rooting ability of the cuttings was recorded and used to confirm the results from the CF data. The use of cardboard versus polystyrene packaging and the inclusion of two treat...

Chloroplast (trnL–F and rbcL) sequences were used to reconstruct the phylogeny of Geraniaceae and Hypseocharitaceae. According to these data Hypseocharitaceae and Geraniaceae are monophyletic. Pelargonium and Monsonia are sisters to the largest clade of Geraniaceae, formed by Geranium, Erodium and California. According to molecular dating and dispersal-vicariance analysis, the split of the stem...

The effects of compost based substrates on growth and nutrition of geranium (Pelargonium zonale cv Lucky Break F2) were investigated. Substrates of manure compost, cotton gin trash compost, municipal solid waste compost and pine bark utilized as potting media for domestic use, produced an underdevelopment of geranium plants with respect to the control. This behaviour is related to the inferior ...
