ten gerbera cultivars (‘labinel’, ‘lilla’, ‘alp’, ‘alberino’, ‘bonnie’, ‘avemaria’, ‘mammut’, ‘lexus’, ‘‘terramixa ’ & ‘sarolta’) were evaluated for their growth, yield and quality characteristics under protected conditions during 2011. among the cultivars studied, there were highly significant variations observed for growth, yield and quality parameters. longest stalk length (60.3 cm) was ...
A pot experiment was carried out to determine the effect of foliage spraying of silicon (Si) on growth and ornamental characteristics of calendula grown under salt stress and greenhouse conditions. A factorial experiment based on completely randomized design was conducted with 3 levels of Si (0, 50 and 100 mg/l) and 3 levels of NaCl (0, 100 and 200 mM) with 4 replications. At flowering stage, S...
phytoremediation is an emerging environmental-friendly technology that can be a promising solution to remediate oil-polluted soils. the impact of high amount of hydrocarbons on growth characteristics of burningbushand common flax was evaluated in this survey. the influence of organic fertilizers was also assessed on growth of plant species in oil-contaminated soil. soil samples in which plants ...
To evaluate the effect of plant growth promoting bacteria (PGPB) on soil physical and chemical indices, yield and its components of two rice cultivars, an experiment was arranged in Rice Researches Institute of Guilan Province during 2009. The experiment design consisted of four randomized complete blocks in a factorial arrangement having 16 treatments in every block. In this research, two fact...
introduction: extracellular matrix (ecm) components significantly influence the growth characteristics of cell, development of spontaneous contractile activity, andmorphologic differentiation. the present study evaluates the effect of ecm ongenotypic and physiologic characteristics of cardiomyocytes derived from embryonic stem (es) cells. material and methods: embryoid bodies derived from mouse...
a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...
In order to evaluate the effect of different levels of benzyladenine, nitrogen and salinity on growth characteristics of pistachio seedlings, cv. Badami Zarand, a factorial experiment with three factors: benzyladenine (0, 250 and 500 mg/L), nitrogen (0 and 100 mg N/kg soil as NH4NO3) and salinity (0 and 2000 mg NaCl/kg soil) was carried out as completely randomized design with three replication...
Risk analysis is an important technique to estimate impacts on the environment for adopting effective measures to avoid risks. This field study was conducted to investigate the risk of brick kiln (BK) smoke on the shoots of Acacia arabica. Different phenotypic parameters including morphology and growth of shoots and epidermal imprints of the leaves were studied in the vicinity of a brick kiln s...
In this study, the effects of four types of mulch including wood chips, municipal compost, sawdust and gravel in three different thicknesses on temperature soil, moisture and growth characteristics of two cultivars of Tagetes (Tagetes patella var Durango Bee and Tagetes erecta var Antigua) were examined in Mashhad area with semi-arid climate. The research was conducted as a split plot based on ...
