The distribution patterns of flavonoids and cyclohexenyl chalcone derivatives in conventional propagated (CP) and in vitro-derived (CPA) field-grown plants of an important medicinal ginger, Boesenbergia rotunda, are described. A total of eight compounds were extracted from six organs (rootlet, rhizome, shoot base, maroon stem, stalk, and leaf) of the CP and CPA plants. Five major chromatographi...

This is the first study that report symbiosis in Cattleya, aiming to isolate and identify mycorrhizal fungi capable of promoting germination this orchid, evaluate development symbiotically propagated individuals. We compared seed percentage, growth index morphometric variables seedlings OMA medium with individuals were non-symbiotically MS medium. Fungi isolates identified by phylogenetic analy...

this study was conducted to find out the influence of in vitro salinity on growth parameters shoot length, number of leaves, number of new buds, the chlorophyll, chlorosis and necrosis and absorption of sodium, chloride, potassium, nitrogen and phosphorus of pear (pyrus communis cv. dargazi) in vitro propagated shoots. the experiment was conducted as a complete randomized design with 5 salinity...

Saponins are secondary metabolites that are widely distributed in the plant kingdom and are often the active components in medicinal herbs. Hence, saponins have a potential for the pharmaceutical industry as antibacterial, virucidal, anti-inflammatory, and anti-leishmanial drugs. However, their commercial application is often hindered because of practical problems, such as low and variable yiel...

Background: Ananas comosus, commonly known as pineapple, is a fruit that is endorsed by the Ministry of Agriculture to be economically important to the island. Tissue culture maybe used as an additional method of propagation to supplement traditional methods to increase productivity. This study was therefore designed to assess the effectiveness of utilising tissue culture techniques to produce ...
