Various formulations of petroleum fractions in the light lubricating oil range provide efficient general insecticides for control of insect pests of citrus and have been used for this purpose for many years. The relatively low cost and high insecticidal efficiency of these materials make it probable that their widespread use in citrus culture will continue for some time. Many types of injury to...

The ranking of hybrids via genotypic values stands out due to its maximum selective accuracy in relation ordering based on phenotypic values, which incorporate environmental effects, causing changes the final classification. aim this study was pre-select cloned pineapple for higher total soluble solids (TSS) and larger fruit mass without crown (FMWC). It evaluated with 364 propagated vegetative...

The effect of fertilizer rate on fruit quality parameters in the black chokeberry (Aronia melanocarpa [Michx] Ell.) cv. `Viking' was studied over three years. A combined N±P±K fertilizer was applied in different rates. Plant height, yield, berry weight, anthocyanin content, content of brown compounds, content of soluble solids, anthocyanin composition and total acidity were recorded for the dif...

food quality, marketability, soluble solids, size and color of nectarine fruit is affected by the intensity and amount of direct sunlight. usually the outer areas of fruit trees get enough light and take the appropriate color. however, in the middle and lower part of trees, due to low light intensity, fruits have no good color and taste and their marketability were not desirable. to improve the...

Pepper species of the genus Capsicum have been cultivated over centuries, producing both pungent and sweet fruit; the pungency is caused by alkaloids called capsaicinoids. Among the five cultivated species, Capsicum chinense is one of the most popular, being native to the Amazon basin. This species is characterized by a wide variety of fruit sizes, shapes and colors, with different capsaicinoid...

in the current research, salicylic acid and putrescine treatments solutions each with 0, 0.5, 1, and 2 mm/l levels were sprayed on the ‘granny smith’ apple trees in three preharvest stages. the treatments were applied based on factorial experiment in the randomized complete block design. weight loss, fruit firmness, total soluble solids (tss), titratable acidity (ta), ph, tss/ta, peel color, an...

Gerbera cut flowers is one of the important and popular cut flowers in the world that regardless of increasing production of this plant in Iran, the duration of its life is short due to rapid wilting petals and bending neck of flower. To increase vase life of gerbera cut flowers cv. ‘Alain Ducasse’, the essences of Eucalyptus and Rosa damascena, the combination of these two essences at a concen...
