The Experiment with nutrient solution was conducted in the glasshouse of the University of Applied and life Science, Vienna, Austria to evaluate the effect of water stress on root and shoot development of seven tomato cultivars. The stress levels were 20, 25 and 30 minutes (withholding water) as low, medium and severe stress. The experiment revealed that the cultivars BR-4 and BR-5 showed compa...

Salinity and heavy metals affect the growth and development of higher plants and also their productivity. In the present study, Cauliflower (Brassica oleracea var botrytis) seeds were allowed to germinate and grow in the absence (control) and presence of different concentrations (50, 100, 250, 500, 750 and 1000 μM) of NaCl, CdCl2, HgCl2 and ZnCl2. Seed germination and growth parameters of seedl...

Araucaria excelsa L. of Araucariaceae family is a beautiful conifer which has a high economic importance in the flower industry. A factorial experiment based on randomized completely block design with two factors: 1. Irrigation intervals in 2, 4 and 6 days (I1, I2 and I3) and 2. The growth bed in pots 3 L included M1 (100 % v/v cocopeat), M2 (100%  municipal waste compost), M3 (100 % vermicompo...

Background: The application of polyamines as a plant growth substance with effect on a wide range of plant growth and development processes include cell division, flowering, senescence delay, membrane stability, absorb active radicals and different stress tolerance and polyamines Function as a anti-senescence and anti-stress agents in the plant and on the other hand the competitiveness of their...

the present study was designed to evaluate the drought tolerance of new sugar beet monogerm hybrids using polyethylene glycol 6000, under in vitro condition. the experiment was carried out as a factorial experiment based on completely randomized design with four replications in sugar beet seed institute, karaj in 2013. 23 new sugar beet monogerm hybrids with two tolerant and normal controls wer...

Effects of cold plasma treatment on soybean (Glycine max L. Merr cv. Zhongdou 40) seed germination and seedling growth were studied. Seeds were pre-treated with 0, 60, 80, 100 and 120 W of cold plasma for 15 s. Results showed that plasma treatments had positive effects on seed germination and seedling growth, and treatment of 80 W had the highest stimulatory effect. Germination and vigor indice...

The root : shoot ratio for Ilex cassine L. grown 7 months in copper-treated containers was less than in nontreated containers. There was less dry weight for roots <5 mm in diameter in copper-treated containers than in nontreated containers in the outer 1 cm of the rootball. Dry weight of roots >5 mm in diameter within the rootball were not affected by copper hydroxide treatment. Coating the int...

take-all disease of wheat (gaeumannomyces graminis var. tritici) (ggt) is one of the most destructive root diseases in the world. it has not been introduced resistant genotype against this disease. in this study, 416 genotype of bread wheat, received from different location of iran and other countries, were evaluated to take-all (t-41 isolate) in greenhouse conditions. root dry weight, shoot dr...
