abstract in order to study the effects on salinity and silicon application on yield and yield components of purslane (portulaca oleracea l.), an experiment was conducted in a completely randomized desgin with three replications and two factors consisted of four different levels of salinity using nacl (0, 7, 14, 21ds/m) and two levels of silicon (application of one mmol sodium silicate and not a...

Accuracy and random selection of seeds when testing the 1000 weight in laboratory is great importance order to ensure representativeness sample precise information for further packaging process. The aim this research was check whether seed counter selects by shape size there a trend during operation at maximum reduced speed. Ten species different sizes were used. replicates 100 counted counter,...

Eighty eight plus trees representing the entire distributional range of Pinus wallichiana (Blue pine or Kail ) in Kashmir Himalaya were sampled to determine the extent and nature of variability and character association in eight cone and seed traits. Wide variations were observed in cone weight (28.16-46.0 g), number of seeds/cone (41.6-90.6) and 1000 seed weight (42.0-67.0 g). Genetic coeffici...

in order to study effect of seed weight on germination and growth of wheat seedling, an experiment in seed technology laboratory of aboureihan paradise university of tehran in 2005 has been done. in this experiment, at first stage, the seeds separated by longitude step, latitude step and set frequency parameters of gravity separator set. in second stage, 10 treatments of 1000 seed weight entere...

this experiment was carried out in factorial arrangement based on randomized complete block design with three replications in agricultural and natural resources research center of markazi province, arak (iran) during 2008-2009 growing season. three application rates of sulphur (s1=0, s2= 40 and s3=80 kg/ha) and three rapeseed varieties (okapi, modena and licord) comprised the experimental facto...

Objective: In order to study the effect of solopotasse fertilizer on yield and essential oil of cumin medicinal plant. Methods: A experiment in randomized complete block design with three replications conducted in kermam city, Iran, in 2013. solopotasse fertilizer in four levels (0, 50, 100 and 150 kg/h) investigated. Plant height, number of umbrella per plant, number of seed per umbrella, 1000...
