The Discovery of the Content Giberellin Acid (GA3) in Extracts Several Plant Spesies. studies have found that application growth regulator can induce seedless seeded varieties and also improve fruit quality non-seeded grapes. It is directly responsible for cell division used horticulture to promote seed germination. high price makes it unaffordable farmers, especially Indonesia, so necessary lo...

The effect of Meloidogyne incognita on growth, general physiological response, and the concentrat ion of reducing and nonreducing sugars at the nematode feeding sites of French Colombard (susceptible) and Thompson Seedless (moderately resistant) Vitis vinifera cultivars was studied up to 2,100 degree-days (DD-base 10 C). Nematode stress dosage, measured as the product of cumulative number of ju...

For vector-borne diseases, interactions between vector, host, and pathogen can influence patterns of disease spread. In particular, previous studies suggest that host genotype may influence disease dynamics because of differences in susceptibility to the pathogen and, therefore, subsequent vector transmission efficiency from these plants. We tested this hypothesis by using the pathogenic bacte...

Fourier-transform near infrared (FT-NIR) reflection spectra of intact berries the grape variety Thompson seedless were used to predict total soluble solids (TSS) content. From an initial dataset, 12 subsets considered by applying variable selection extract reflectance values at wavenumbers most correlated chemometrically measured TSS The datasets processed both multiple linear regression (MLR) ...

The effects of N-benzyladenine (BA) and N-(2-chloro-4-pyridyl)-N-phenylurea (CPPU) in combination with gibberellic acid (GA3, 100 mg l ) on berry setting and development and on the endogenous level of polyamines (PAs ) were investigated in order to elucidate the role of PAs in the setting and development of GA3-induced seedless grape berries affected by cytokinins. BA stimulated berry developm...
