![]() ![]() In flowers, synthesis activity was observed in the pedicel joints and ovaries, whereas in the fruits it was strongest during early seed development and was associated with the locular jelly and seeds. In young tomato seedlings BR synthesis activity was observed mainly in apical and root tissues undergoing expansion. Researches showed that brassinosteroids are essential for many physiological functions in plants, however little is known concerning where and when they are synthesized. (1979) isolated the biologically active molecule. Brassinolide (BL) was the first isolated brassinosteroid when Michael et al. (1970) reported that cell division and elongation were promoted by the treatment of organic extracts of rape (Brassica napus L.) pollen. These were first explored when Mitchell et al. Brassinosteroids (BRs) are a class of poly hydroxyl steroids, which have been recognized as a class of plant hormones. The sugar/ organic acid ratio is a major parameter of strawberry taste. This acid contributes greatly to fruit titratable acidity, which declines gradually during fruit development. The major soluble sugars in strawberries are glucose, fructose, and sucrose. The major soluble constituents of maturing and ripe strawberries are soluble sugars and organic acids. Numerous biochemical changes are observed during strawberry development and especially during fruit ripening. Moreover, there appears to be genetic variations for these fruit quality traits. Fruit soluble solids, sugars, titratable acidity, and organic acids at maturity are quantitatively inherited. Numerous studies have addressed strawberry sweetness and acidity. Fruit with intense flavor also have high titratable acidity and high soluble solids. Several studies have been devoted to strawberry aroma. Three major components of fruit organoleptic quality are flavor, sweetness, and acidity. ![]() Numerous breeding programs have been aimed at improving strawberry taste and disease resistance. The desired effects was obtained through the activity of fertilizer’s components, which very often belong to different groups of natural hormones, elicitors, vitamins, flavonoids, amino acids, etc. New environmentally friendly mineral-organic fertilizers can improve fruit quality and yield of dessert strawberry cultivars. Fruit production cost for the fresh market needs to be calculated and efficient methods and technologies also should be taken into consideration. High quality of the fruit for the fresh market is an important factor attracts customers and determines their choice and prices. Introduction: Recently, strawberry growers have been mostly interested in growing cultivars for the fresh market because of its profitability, but on the other hand it requires more complicated technologies and well-educated workers.
