Flavonoids which are polyphenolic substances are found in different vegetable and fruits and they have anti-oxidant properties. Epidemiological studies showed that flavonoids reduce the prevalence of cardiovascular disease. On the other hand, the usage of synthetic antioxidants have been limited because of their toxicity and, there are different researches to find better natural antioxidants. This survey investigates the effect of some pure flavonoids such as kaempferol, quercetin, morin and rutin on red blood cell (RBC) hemolysis and their -SH capacity as membrane protection indicator. The flavonoids solutions were prepared. Rate of RBC hemolysis and -SH capacity of cell membrane were determined by spectrophotometer. 2,2´azobis2 amidino propane dihydrechloride (AAPH) was used to induce RBC peroxidation. The effect of each flavonoids on RBC hemolysis was examined in 3 concentrations (0.15, 5, 10) μg/ml but for investigating the effect on -SH groups only the highest concentration (10 μg/ml) of each flavonoids were used. In all cases, the antioxidant activity was dose-dependent. Rutin showed the highest inhibitory effect on RBC hemolysis than other flavonoid, that was 42.5. Also kaempferol, rutin, morin protect -SH groups 6%, 23.3%, 26.4% respectively. Results showed that flavonoids and plants contain flavonoids can be used as natural antioxidants for treatment and prevention of diseases which their pathogenesis are lipid peroxidation.

After collecthing the Dorema ammoniacum seeds, they need to pass a period in coldness, untill they grow up. So the periods of 0, 20, 25, 30 and 35 days were selected to determine the best coldness periods. Also some seeds were selected as control treatmeat with out passing this period. Temperatures for experimental treatments was 3-4˚Cand control treatment was put in room temperature of (13– 16˚C). Experimental treatment seeds were planted in vase and after two months , vegetaing buds were counted. By analysing the results , the best coldness period was determineed as 30 days. Dorema ammoniacum seeds were collected from their naturel inhabitat to determine the best sowing depth. Three treatmeats were considered to be cultivated in the depth of 0.5 –1 and 1.5 centimeters. Seeds were planted in 30 plastic vases. Buds were counted after growing up and the results were analysed. The result shows that there is no significamt difference between these three treatments of depth and those three cultivation depths are suitable for seed germination (vegetation).

Soil water supply is an important environmental factor controlling seed germination. If the water potential is reduced, seed germination will be delayed or prevented. Basil (Ocimum basilicum) is an annual herb plant of Lamiaceae family. The essential oil of basil, mainly used in food industries and perfumery, also possesses antimicrobial activity. To study the effects of water stress on seed germination and seedlings growth of basil, an experiment in completely randomized design with seven treatments and three replications was conducted. Seeds were subjected to water stress using polyethylene glycol (PEG 6000) at seven concentrations (0, 5, 15, 20, 25 and 30%) representing water potentials of 0, -0.03, -0.19, -0.41, -0.67, -0.99 and -1.35 MPa. The results showed that water stress have significant effects on seed germination of basil. Seeds treated with -1.35 MPa did not germinate. The few seeds that did germinated in -0.67 and -0.99 MPa water potential, did not produce seedlings. There was no significant difference between 0 to -0.41 MPa for germination percentage. Germination rate showed significant reduction at -0.41 compared to 0, -0.03 and -0.19 MPa water potential. On the other hand, the results of this study showed that different levels of water potential (0, -0.03, -0.19 and -0.41 MPa) have significant effects on seedling growth. With decreasing water potential (from 0 to -0.41 MPa), plumule length, fresh weight of radicle, plumule and seedling decreased but radicle length, dry weight of radicle, plumule and seedling, the radicle length to plumule length ratio and the dry weight of radicle to dry weight of plumule ratio increased. It could beconcluded that in water stress condition, root growth of basil was affected lower than shoot growth.

Plants produce a diverse array of secondary metabolites. These compounds may be synthesized during normal growth and development and accumulating only in response to pathogen attack or stress. Interest in these molecules stems from their medicinal properties, antimicrobial activity and their likely role as determinats of plant disease resistance. Daisy (Bellis perennis L.) accumulates secondary compounds (triterpenoid saponins and anthocyanins) in response to SA and pathogens. The results of the research indicates that the amount of secondary compounds (saponins and anthocyanins) in treated plants with SA were more than in the control plants. The amount of compounds in infected plants and without SA was more than in the control plants. When infected plants were treated with SA, an increase of compounds was shown in plants. The peaks observed in HPLC and their comparision with compounds standard confirms the results mentioned above. It is concluded that SA have significantly reduced disease severity and increase the amount of secondary compounds in infected and non-infected Daisy plants.
