Background: Grapes are mostly propagated by hardwood cutting. Most of the time, auxin (Indole Butyric Acid) is used in liquid form. There are some problems associated with using auxin in liquid form viz. cell sap may exude from cutting end on dipping in solution that may lead to contamination, every time auxin solution should be freshly prepared etc. In order to address these problems, auxin hormone is used in powder form by using Talcum powder. Methods: In the present investigation, rooting powders containing different concentration of auxin were tried for root induction behavior. Approximately 15-20 cm long and 1-1.5 cm thick hardwood cuttings of grapes were taken. Result: The results indicates that grape cuttings treated with Indole Butyric Acid @ 3000 ppm in powder form was found to be best for root induction behavior. However, in most of the cases observations were at par with Indole Butyric Acid @ 2000 ppm (powder form) and with treatment @ 2000 ppm in liquid form but if we consider other benefits like long shelf life, no contamination etc. It can be concluded the rooting hormone in powder form should be considered better alternative to liquid form for root induction.

The Isabel grape (Vitis labrusca × Vitis vinifera L.) is the most produced grape in Brazil, however, it has a short postharvest period due to rapid degradation during storage. The use of coating has been an alternative to prolong the shelf-life of fruits. The objective of this work was to evaluate the postharvest quality of 'Isabel' grapes coated with tamarind (Tamarindus indica L.) seed starch. The experimental design was completely randomized with five treatments with edible coating based on tamarind seed starch, at concentrations of 0, 0.5, 1, 1.5 and 2% and five replications. The grapes were immersed in the solutions with different concentrations and stored in B.O.D. at 12 ± 2 ° C and 85 ± 5% relative humidity for 12 days. Weight loss, color, pH, soluble solids, total titratable acidity, relationship between soluble solids and acidity, anthocyanins, flavonoids and vitamin C were evaluated. The 2% coating of tamarind seed starch was the most efficient, providing shelf life in 12-day grapes when stored at 12 ± 2 ° C and 85 ± 5% RH, and maintaining the main quality aspects, with higher SS / TA ratio and vitamin C.

The cutting shoot is one of fast growing Malalueca cajuputi seedling. The cutting shoot used from plantation and cajuputi seeds in induction shed. Then, to fast root induction on the cutting shoot must be special treatment is giving hormone from outside. Giving hormonal in Perum Perhutani by IBA (Indole Butyric Acid), but IBA is one of hazard and toxic substances (B3) and not eco-friendly. The object of studies to prove the induction effect on the growth of cajuputi cuttings shoot, the influence of IBA hormone and natural hormone extract of onion to growth of cajuputi cuttings shoot, and determine the best of hormone to growth of cajuputi cutting shoot. Data collected by measuring height of the cajuputi cuttings shoot from the base of stem which has been marked up to the tip of shoots. The measurement of height of cajuputi cutting shoot was repeated 6 (six) times for 90 days so that measurement was done every 15 days. Besides that, there is addition of leaf number since cuttings planted up to 90 HST and root appearance at each treatment. The result of research IBA gives the best growth effect for shoots from Induction that is the highest height compared with other hormones. So this study recommended using shoots of induction with IBA hormone to best growth and eco-friendly.

Objective: Grape seed oil (GSO) from Vitis vinifera L. is a liquid vegetable oil which has been used mainly for its linoleic acid content. However, there are many efforts to convert the liquid form of the oil into a solid form due to the instability under storage condition. The aim of this study was to convert GSO into the solid microcapsules by emulsion crosslinking method with gum arabic as a coating polymer.Methods: The GSO was formulated with gum arabic in the ratios of 1:2, 1:3, 1:4, and 1:5. Gum arabic solution was emulsified with GSO using Span 80 and glutaraldehyde. The emulsion was dropped into a beaker glass of isopropyl alcohol to form microcapsules. The microcapsules were dried at 70 °C. Then, they were characterized in terms of morphology, particle size, swelling index, water content, and entrapment efficiency.Results: The produced microcapsules of GSO showed white yellowish color and spherical shape. The particle size of F1, F2, F3 and F4 microcapsules were 69 μm, 82 μm, 125 μm, and 131 μm, respectively. The water content of the F1–F4 ranged from 4.37±0.34 to 5.70±0.92% and swelling indexes were ranged from 5.54±0.01 to 5.94±0.04. The value of entrapment efficiency of F1, F2, F3, and F4 were 17.33±0.603, 20.73±0.678, 34.22±1.195, and 67.15±2.019%, respectively.Conclusion: The results of this investigation showed that GSO could be converted into the solid spherical microcapsules by emulsion crosslinking method using gum arabic. Taken together, this study has provided the most promising formulation of GSO microcapsules for further production in pharmaceutical industry.
