Effects of salinity and ascorbic acid on growth properties of German chamomile (Chamomilla recutita L)

Chamomile is one of the most important medicinal plants known to Human And due to its increasing use in pharmaceuticals, cosmetics, hygiene, perfumery and flavoring preparation of food isvery important. Soil salinity is one of the main barriers and constraints in the production of agricultural, such as medicinal plants is optimal. Ascorbic acid is a powerful antioxidant compounds that can reduce the effects of salinity on plants. In order to, test in the form of split plot in a randomized complete block design, in the city ofValley City in 1390 with three replications. Test parameters include salinity of Irrigation water, with 3 levels (0, 50 and 100 mM) and ascorbic acid with 3 levels (0, 5 and 10 mM). The results showed that increasing salinity decreased height, biomass, dried flowers and seed yield, but the yield was significantly increased intake of ascorbic acid. Interaction of ascorbic acid and salt on the dried flowers was significant. The most of dried flowers Yield in salinity of 0 mM and 10 mM ascorbic acid, the amount of 1,123 kg per hectare. The results of this study indicate the beneficial effects of ascorbic acid to reduce the harmful effects of salinity on the quantitative Yield of German chamomile herb.
