Total soluble solid (TSS) content is commercially used as fruit quality index because of its high positive correlation with sugar content. In the present study, The effect of foliar application of naphthalene acetic acid (NAA) with different concentrations (0, 25, 50, and 100 mg.L-1) at 4 true leaf and fruit set stages and plant training (pruning and thinning) on TSS and soluble sugar (i.e. suc...

in this study the effects of plant growth regulators including; ga3 (0 and 50 mg/l) and ethephon (0 and 500 mg/l) were studied on the quality properties of two grape cultivars (perlette and yaghuti). at the harvest time, some physicochemical characteristics such as fruit cluster weight, fruit diameter, length, volume and l/d ratio, flesh firmness, fresh weight, ta, ph, tss and fruit color were ...

The changes in some physicochemical properties, sugar, organic acid and volatile compound contents fresh Verdani grape (Vitis vinifera L.) juice (FGJ) were evaluated the production of its traditional molasses (pekmez). After production, total soluble solid (TSS), titratable acidity (TA), glucose, fructose, malic, citric succinic concentrations increased (P

in present research the effects of four levels (0, 0.5, 1, 2 mm) of each of salicylic acid and putrescine treatments on the quality improvement of granny smith apple fruit were studied. factorial experiment in randomized complete block with three replications on 16 trees, eighteen years in researcher station of agriculture university of tehran was designed. for this purpose the trees were spray...

Chilling damage under 15ºC in anthurium cut flowers reduces the vase-life, quality and marketability of the product. In the present experiment, GABA postharvest treatment (0, 1 and 5 mM) was studied on the vase-life, total soluble solid (TSS), H2O2 content, proline content, spathe browning, catalase and superoxide dismutase enzymes activity of Anthurium andraeanum...

strawberry (fragaria ananassa duch.) is a good source of natural antioxidants. fruits from eight strawberry (fragaria ananassa duch.) cultivars (‘kurdistan’, ‘merck’, ‘camarosa’, ‘paros’, ‘queen elisa’, ‘ventana’, ‘selva’ and ‘pajaro’) were harvested at ripen stage and analyzed for total phenolic content, total anthocyanin content, vitamin c, total soluble solid and total antioxidant activity. ...

abstract having no exact knowledge of most appropriate harvesting time in kiwifruit grown in different regions of guilan province, as well as the low storage longevity of the fruits are the most important factors causing considerable reduction in both marketability and export affairs. in this study, the influence of fruit quality in term of harvesting time on the postharvest quality and food va...

harvesting time of kiwifruit can influence quality characteristics. the current research was carried out according to a completely randomized design with three replications at faculty of agricultural sciences, university of guilan in 2009. weight loss, flesh firmness, total soluble solid (tss), titritable acidity (ta), ascorbic acid, total phenol content and antioxidant capacity of harvested fr...

Aim: The interaction of mechanized pruning systems and soil organic amendment can increase vine productivity. However, since the in productivity may affect grape composition, this study aimed to understand effects between these two practices.Methods materials: Two field trials were implemented Shiraz vineyards different wine regions. Mechanical hedge was compared with hand spur four amendments ...
