chlorogenic acid, a pharmacologically important compound, is a phenolic compound that occurs in certain commonly used medicinal herbs. we looked for the presence of this compound in the callus cultures of varthemia persica dc (var. persica ). we have evaluated the conditions for establishment of callus cultures of v. persica and the in vitro production of chlorogenic acid. callus was initiated ...

background & aim: clematis is an ornamental and medicinal plant that is primarily planted as an ornamental plant. clematis orientalis is native to asia and central europe, used as an antiseptic and refrigerant. the propagation of clematis is very important. in this study, the effects of plant growth regulators on rooting and growth of the plants in vitro culture were examined. experimental:...

in order to investigate the effect of different levels of cycosel and naphthalene acetic acid on some vegetative traits and on essential oil yield from rose-scented geranium (pelargonium graveolens heritier), an experiment was conducted in 2008 in the research greenhouse of horticulture department of zanjan university. the study was arranged as a factorial experiment, based upon a randomized co...

background: fenugreek (trigonella foenum - graecum l.) is an annual medicinal plant belongs to the legume family and has anti-diabetic, anti-fertility, anticancer, anti-microbial, anti-parasitic and hypocholesterolaemic effects. objective: evaluation of growth and trigonelline /mucilage content in fenugreek under application of plant growth regulators (pgr). methods: the experiment was conducte...

generally, fruit trees should produce sufficient yield annually through their economic life. fruit trees usually produce flowers over their ability of productivity. if all of the flowers are converted to fruit, the tree will be weak and poor smaller fruit will be produced and it may cause alternate bearing. thus some flowers must be removed by hand, mechanically or chemically. in this study, th...

Micropropagation of Calophyllum brasiliense Cambess. (Clusiaceae) is a way to overcome difficulties in achieving large-scale plant production, given the recalcitrant nature of the seeds, irregular fructification and absence of natural vegetative propagation of the species. Cultures were established using nodal segments 2 cm in length, obtained from 1-2 year old seedlings, maintained in a greenh...
