Hypericum perforatum L. (St. Johns’ wort) is the most commercially important species of the genus Hypericum and contains a wide range of components including naphthodianthrones, phloroglucinols, tannins, xanthones, phenolic acids and essential oil. In order to establish an efficient protocol for regeneration, the effects of explant type and plant growth regulators on direct and indirect shoot r...

Many vigorous herbaceous perennials need early growth regulation. Treatment at the plug stage could improve early growth control or maintain product size in the plug tray. Concise (uniconazole, Fine Americas, Inc.), is a growth regulator labeled for use on ornamental greenhouse crops in the US. We treated plugs of five herbaceous perennials with a 2-minute dip into 0, 1, 2, 3, 4 or 5 mg/L Conci...

1. Functional traits contribute to the success of invasive plants. These traits can reflect inherent properties or they can be new adaptations from evolutionary responses to escape from natural enemies of the introduced range. We tested the hypothesis that genetic shifts in morphological and physiological traits have occurred between native and invasive populations of Sapium sebiferum . 2. Sapi...

one method of seed placement into the soil as regards no-till system is the use of punch planting by which one can plant through a considerable depth of surface residue. the study was conducted using a 2?3 split-plot experimental design of three replications. the factors considered were two types of plantes (conventional planter vs. hinging pneumatic punch planter) and three levels of wheat res...

application of salicylic acid (sa) as a phytohormone has been increased due to resistance to stresses such as drought. the main goal of this experiment was to evaluate the effects of sa on morphological and physiological characteristics of cucumber seedlings under drought stress. for this purpose a factorial trial based on completely randomized design was conducted with 5 levels of sa (0 (contr...

This study aims to determine the most appropriate method and sterilization technique for growth of abaca weevil shoot explants taken directly from field effect dose regulator BAP (Benzile amino purine) on feed. (Musa textilis Nee). through in vitro techniques. uses multilevel using direct observation, namely when have become shoots. The results showed that was a fixed with bayclin treatment con...

Chrysanthemum indicum plant is a valuable and beneficial herb for human health. In this paper, we present the results of in vitro propagation Da Lat. The showed that MS medium supplemented with 25 g/l sucrose, 9 agar, pH 5.8 was best shoot regeneration growth (shoot height 2.41 - 2.47 cm, 1 shoot/explant). media BA (0.1, 0.5, 1, 1.5, 2 mg/l), Kinetin mg/l ) TDZ mg/l) were unsuitable C. indicum....
