Bermudagrass [Cynodon dactylon (L.) Pers.] is a perennial grass and has been long used as a medicinal herb in Iranian traditional medicine to treat varied ailments. Different parts of bermudagrass such as leaves, stolons, rhizomes and culms are rich sources of metabolites such as proteins, carbohydrates, mineral constituents, β-sitosterol, flavonoids, alkaloids, glycosides and triterpenoides. G...

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...

From a comparison of the effects of seven growth retardants and abscisic acid (ABA) on various growth systems, it was found that the gibberellin-regulated growth of lettuce hypocotyls was uniquely inhibited by the growth retardant, alpha-cyclopropyl-alpha-(4-methoxyphenyl)-5-pyrimidine methanol (EL-531). Auxin-regulated growth of coleoptile sections was inhibited by Phosfon and only slightly by...

The effectiveness of 12 chemical compounds (azoxystrobin, carbendazim, chlorothalonil, fenarimol, folpet, mancozeb, myclobutanil + mancozeb, prochloraz + carbendazim, tebuconazole + triadimefon, tetraconazole + chlorothalonil, tiophanate-methyl, tridemorph + epoxiconazole) in the control of Puccinia horiana was tested on chrysanthemum cv. Fiji Yellow. Additionally, their influence on plant grow...

As a candidate for bioherbicide, 4,8-dihydroxy-1-tetralone (4,8-DHT) was isolated from Caryospora callicarpa epicarp and its two enantiomers, S-(+)-isosclerone and R-(-)-regiolone, were separated by chiral high-performance liquid chromatography (HPLC) on a Chiralcel OD column with chiral stationary phase (CSP)-coated cellulose-tris(3,5-dimethylphenylcarbamate). Then, the phytotoxicity of 4,8-DH...

The plant growth retardant S-(+)-uniconazole (UNI-OH) is a strong inhibitor of abscisic acid (ABA) 8'-hydroxylase, a key enzyme in the catabolism of ABA, a plant hormone involved in stress tolerance, stomatal closure, flowering, seed dormancy, and other physiological events. In the present study, we focused on the two polar sites of UNI-OH and synthesized 3- and 2''-modified analogs. Conformati...
