Saffron or Crocus sativus L. (C. sativus) has been widely used as a medicinal plant to promote human health, especially in Asia. The main components of saffron are crocin, picrocrocin and safranal. The median lethal doses (LD50) of C. sativus are 200 mg/ml and 20.7 g/kg in vitro and in animal studies, respectively. Saffron has been suggested to be effective in the treatment of a wide range of d...

In North Carolina, approximately 8% of the cucumber (Cucumis sativus) yield is lost to root-knot nematodes (Meloidogyne spp.) (Main and Gurtz, 1989). No resistance was found in cucumber after screening of 900 cultigens for resistance to Meloidogyne incognita race 3 (Walters, 1991). African horned cucumber (Cucumis metuliferus) has resistance to M. incognita (Fassuliotis, 1967; Walters, 1991), a...

Hydroxycinnamoyltransferases which catalyze the formation of O-sinapoylcholine (sinapine) using l-0-sinapoyl-ß-D-glucose as acyl donor have been isolated from seeds of radish (Raphanus sativus L. var. sativus) and mustard (Sinapis alba L.) and purified 420and 293-fold, respectively. The enzymes (“sinapine synthase”) had apparent molecular weights of about 60,000 daltons and showed highest activ...

Stories abound about the medical abuses that have come to define medicine and the "pseudo"-neurosciences in the Third Reich. Well known are the Nazi program of euthanasia and the neuroscientific publications that arose from it. Nevertheless, during this widespread perversion of medical practice and science, true medical heroics persisted, even in the concentration camps. In December 1942, inmat...

The present investigation focused on the effects of plant and seed diffusates of Parthenium hysterophorus L. on seed germination of Raphanus sativus L. Level of glucose in germinating seeds as an indirect measure of amylase activity was estimated. About 91.66% viable seed of Raphanus sativus were treated in different concentrations of rhizospheric soil diffusates (PD) and germinating seed diffu...

a flavonol, kaempferol, isolated from the fresh flower petals of c. sativus l. (iridaceae) as the sole component. the structure of the compound was determined by chemical and spectroscopic methods.

Current studies elucidate the metal stress attenuation potential of melatonin in Cucumis sativus seedlings growing in cadmium contaminated conditions. Melatonin is an indoleamine molecule, capable of ameliorating environmental stresses and regulate plant growth. Seeds of C. sativus were immersed in different levels of melatonin and grown under cadmium stress for 15 days. Cadmi...

Introduction In Tunisia the genus Lathyrus is represented by 15 native species , distributed essentially in marginal environments in the north of the country. Many of them are of considerable agronomic interest as forage (L. ochrus and L. articulatus) and as human food (L. cicera and L. sativus). These species are under utilised and in the past little effort has been made to expand the selectio...

In the present investigation was carried out to find out the impact of Triadimefon(TDM) and hexaconazole (HEX) triazole fungicides on the leaf anatomy of Radish (Raphanus sativus L.) The plant was treated with one litre of aqueous solution containing 20 mg -1 triadimefon (TDM) and 20mg -1 hexaconazole (HEX) on 23,35 and 53, days after sowing (DAS) by soil drenching. The plants were harvested on...
