ABSTRACT An essential factor for the formation of a native orchid seed bank is identification viability stored seeds. This study aimed to determine methodology optimizing tetrazolium test, in seeds two Orchidaceae medicinal species Brazilian Savanna. Seeds Miltonia flavescens Lindl. and Schomburgkia crispa were submitted three pre-conditioning conditions: no soaking (control), sucrose solution ...

We investigated the identity and genetic diversity of more than 100 isolates belonging to Phyllosticta (teleomorph Guignardia), with particular emphasis on Phyllosticta citricarpa and Guignardia mangiferae s.l. occurring on Citrus. Phyllosticta citricarpa is the causal agent of Citrus Black Spot and is subject to phytosanitary legislation in the EU. This species is frequently confused with a ta...

Iris gatesii is a rare bearded species in subgenus Iris section Oncocyclus that occurs in steppe communities of southeastern Turkey. This species is not commonly cultivated, but related species in section Iris are economically important horticultural plants. The complete plastid genome is reported for I. gatesii based on data generated using the Illumina HiSeq platform and is compared to genome...

The Orchidaceae are one of the most species-rich plant families and their floral diversity and pollination biology have long intrigued evolutionary biologists. About one-third of the estimated 18,500 species are thought to be pollinated by deceit. To date, the focus has been on how such pollination evolved, how the different types of deception work, and how it is maintained, but little progress...

The germination power of orchids (Orchidaceae family) seems to betoo weak due lack of albumen. The study carried out with various treatments including pollination time and GA3 for breaking dormancy and increasing seed germination of orchids. The effect of pollination time (8 periods from January to August) and gibberellic acid (0, 500, 1000 and 1500 mg L-1) were studied on germination of Phalae...
