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...

The growth and development, from fertilization to maturity, of the fruit of Cocos nucifera var. Nana form pumila and its components, were studied in terms of dry matter accumulation. The development of the fruit showed an approximately sigmoidal pattern with a substantial linear phase during which most of the increase in dry weight occurred. During the linear phase of growth the rate of dry mat...

Pruning is crucial to balance productivity and fruit quality in blueberry orchards. Slight, conventional and severe pruning treatments were applied on 4and 5-year old bluberry plants cultivar ‘Brigitta’ to evaluate their effect on yield, leaf area, gas exchange and fruit load as driver of fruit quality traits. Yield and berries per plant decreased with increasing pruning severity, whereas canop...

the effect of ca, zn and b spray application on preharvest fruit drop, sugars, calcium, zinc, and boron concentrations and as well on some physicochemical fruit properties of five commercial asian pear cultivars (‘ks’7, ‘ks’8, ‘ks’11, ‘ks’12 and ‘ks’14) was investigated under tehran province,s environmental conditions. trees were sprayed one month past fruit set until harvest within two week in...

an experiment was conducted to determine the effect of paclobutrazol (pbz) and different irrigation amount on growth of aerial parts, leaf minerals and root performance in young olive plants cv. ‘manzanillo’ in the department of horticulture, faculty of agriculture, tarbiat modarres university in 2000. a split plot experiment in time was used based on a completely randomized block design with f...
