In order to investigate the effect of salinity and cadmium (Cd) on yield, chlorophyll content and antioxidant activity of Kochia plant, a factorial experiment in a completely randomized design with three replications was conducted under greenhouse conditions. The experimental treatments included five Cd levels (0, 5, 30, 60 and 90 mg Cd kg-1 soil as cadmium sulphate) and three salinity levels (...
Optimizing the effectiveness of herbicides by additives is one of the ecological and economical approaches for weed management. The aim of this study was to investigate the effect of vegetable oils on the efficacy of clethodim herbicide in control of foxtail as a factorial based on a completely randomized design including clethodim concentration in six levels (0, 7.5, 15, 30, 60 and 120 g ai pe...
awareness of the effects of water deficit on quality and quantity yield of orange is essential for product managing at water shortage conditions. in this regard, present study was conducted in an orange garden of babol area in 2011 in a completely randomized design with 5 treatments and 5 replications. experiment treatments included full irrigation (fi), regulated deficit irrigation (rdi) and p...
Woad (Isatis cappadocica Desv.) is a herbal plant, native to central and western Asia and from Brassicaceae family. In this research, we have investigated the effects of different irrigation levels on plant morphological and physiological attributes including canopy area, roots and shoots dry and fresh weight, roots length, proline concentration, shoots soluble carbohydrates content and antioxi...
Chiko is an important tree fruit crop growing under semi-arid conditions. Kherol is mainly used as a rootstock for sapota which has seed germination problem. The shortage of irrigation water is one of the most important factors limiting agricultural production in arid and semi-arid areas. Irrigation with several dilutions of seawater can act as replacement water resource. Extensive studies have...
Establishment of seedlings at early growth stages of crop plants as one of the most important determinants of high yield is severely affected by soil salinity. Therefore, high germination rate and vigorous early growth under saline soils is preferred. In this study 15 wheat (Triticum aestivum L.) cultivars were used to investigate the effects of three salinity concentrations including 4, 8 and ...
We report the results of a research carried out in Turkey in 2004 to determine the effectiveness of different levels of pumice amendments to soil using strawberry plants. Two grades (2-4 mm and 4-8 mm) of pumice were added to soil and three amendment levels (15%, 30% and 45% by volume) were applied. Finally 6 different growing media types were formulated. The amount of moisture retained at diff...
By incubating explants from Actinidia arguta seedlings on a nutrient medium supplemented with 20 to 30 micromolar N(6)-(Delta(2)-isopentenyl)adenine (i(6)Ade) and then measuring zeatin (io(6)Ade) accumulation in tissues, the distribution of i(6)Ade hydroxylase activities in whole plants could be determined. Based on analyses with three entire plants, it is estimated that, as an organ system, ro...
In recent years, the use of soil microbial potential including arbuscular mycorrhizal fungi is widely considered to enhance the better growth and nutrition of plants. This research was conducted in order to study the impact of mycorrhizal fungi on the increase of yarrow production and the plant establishment affected by the symbiotic ...
to investigate the effects of methyl jasmonate growth regulators on growth characteristics, fruit number and fruit yield of ‘semsuri’ melon, an experiment at the field of shahid bahonar university was conducted in summer 2012. melon (cv. ‘semsuri’) is widely cultivated in iran and therefore increasing the fruit yield and quality of this cultivar is necessary. some growth regulators including me...
