in order to study the effects of cppu and ga3 on fruit quality and quantity of sultanina grapes, a factorial experiment in a randomized complete block design was implemented in a commercial vineyard near bonab city (west azerbaijan province). the spraying was done at fruit set stage using cppu and gibberellic acid. according to the results, it was found that these plant growth regulators had a ...

an analysis of the stages of crop growth presents an important step in the improvement of production management. through growth analysis, planning for planting systems, fertilization, pruning operations, harvest time as well as obtaining economical yield can be more accessible. therefore, a development of mathematical models simulating plant growth would be helpful in improving crop management,...

experiments were carried out in a commercial orchard during 1994, 1995 and 1996 to determine the influence of chemical thinning on characterisics of fruit and alternate bearing of native olive (olea europea l) cvs. dezfoul and fishomi at early fruitlet stage. in 1994, branch sprays of naphthalene acetic acid (100, 150 and 200 mg/l), naphthalene acetamide (200 and 300 mg/l) and urea (0.6 and 1.2...

effect of three different levels of fe-eddha foliar application and soil application of nitrogen on some quantitative and qualitative characteristics of apple (cv. fuji) grafted on maling-9 was evaluated. this experiment carried out at the experimental field of tehran university, in 2013. the factorial experiment was carried out as randomized completely block design (rcbd) with three replicatio...

optimal nutrition of grapevine is one of the most important factors that affect the quantity, quality and time of fruit ripening. to increase the quantity and quality of ‘askari’ cultivar, a factorial experiment in a randomized complete block design with three replications was conducted at shahrekord in 2010. treatments consisted of four levels of potassium sulfate fertilizer (zero, 300, 600 an...

Light is an important environmental factor for fruit development and ripening in pepper plant. Fruit bagging is a significant agrotechnology practiced for the illumination regulation of fruits; some previous researches have shown that fruit bagging could improve the appearance and external quality of fruits and cause them to mature early. However, it would decrease the intrinsic qualities of fr...

Heterogeneity in fruit quality constitutes a major constraint in agri-food chains. In this paper the sources of the heterogeneity in pineapple in the field were studied in four experiments in commercial pineapple fields. The aims were to determine (a) whether differences in pineapple fruit quality among individual fruits are associated with differences in vigor of the individual plants within t...

With its four species, Anchusa is one of the weedy genera of Boraginaceae in Iran. Its species are distributed in different habitats. In this study, the fruit morphological and micro-morphological features of the Anchusa taxa have been considered, so as to evaluate their diagnostic value. Eight qualitative and quantitative fruit features from 12 accessions of A. italica, A. strigosa, A. arvensi...

New shell-type stationary phases are widely used in fast chromatographic measurements. These columns provide more efficient separation, when applied in a conventional high-performance liquid chromatography instrument, than columns with fully porous particles, and the volume overload of core-shell particles is 60% of the value obtained for fully porous particles. Additionally, to achieve adequat...
