In order to investigate the relationship between morphological properties and choose suitable criteria for improving this research yield on ten new breeding lines and varieties of rice (control) modified rice cultivation area (Shiroodi cultivar) in the crop during 2010 in Tonekabon Rice Research Station in a randomized complete block design with four replications. The results showed that rice g...
abstract growth retardants are new chemical organic compounds that increase period of flowering, leave chlorophyll, lateral shoot number, flower number and decrease vegetative growth. they also increase dry, cold and heat tolerance. paclobutrazol and cycocel are examples of these compounds. this study was conducted to evaluate the effect of paclobutrazol and cycocel on some quantitative and qua...
This experiment was conducted with the objective of evaluating the performance sage (Salvia officinalis L.) in different agroecology of Ethiopia for morpho-agronomic and chemical traits at Wondo genet, Hawassa, Qoqa and Holleta for two years from 2011/2012 to 2012/2013 cropping seasons. Data on plant height, branch number/plant, fresh leaf weight/plant, fresh stem weight/plant, above ground bio...
In the temperate zone of Japan, Pinus densiflora Sieb. et Zucc. bears needles of up to three age classes in the upper crown and up to five age classes in the lower crown. To elucidate the effects of leaf age on photosynthetic parameters and its relationships with leaf mass per unit area (LMA) and leaf nitrogen (N(l)) concentration on an area (N(a)) and mass (N(m)) basis, we measured seasonal va...
In order to evaluate the role of paclobutrazol (PBZ) and prohexadione-calcium (ProCa) in reduction of vegetative growth and improvement of reproductive growth of strawberry (cultivar Paros), a 4-replicate completely randomized design was carried out in greenhouse. ProCa in three concentrations of 0, 100 and 150 mg L-1 and PBZ in four concentrations of 0, 60, 90 and 120 mg L-1 were sprayed on th...
to evaluate the effect of slow release fertilizer and humic acid on quality of new guinea impatiens (impatiens hawkeri), an experiment established in complete random design with 15 treatments and three replications. treatments were slow release fertilizer (12-11-18-2.7mgo-8s) in five levels (0, 1.5, 3, 4.5 and 6 kg/m3) and humic acid in three levels (0, 2 and 4 kg/m3) that mixed with medium cul...
In order to study the morphological characteristics and yield of leafy corn hybrids, and comparie them with those of commercial hybrids, an experiment was conducted in the research field of Agricultural College, Tarbiat Modares University in 2005. A complete block design was used with three replications. Hybrids were obtained from crosses between leafy inbred lines and also commercial inbred li...
