| Abstract | ||
| Percent of bud fertility, growth and fruiting of Thompson Seedless grapevines in response to foliar application with GAl, urea and potassium sulphate were studied during 2001 and 2002 seasons. Results showed that bud fertility % was minimized in vines when sprayed with GAJ and/or urea, while maximized in vines sprayed with potassium sulphate. Growth parameters were greaUy promoted by GAJ, urea and potassium sulphate together. Wood ripening was maximized in vines sprayed with potassium sulphate. Yet, this treatments had no considerable effect on number of clusters/vine, while obviously Improved the yield (kg) compared with the control. Weight and dimensions of cluster and berry were positively affected by foliar application of GA), urea and potassium sulphate. Application with GAJ and potassium sulphate were responsible for obtaining unfavorable and favorable effects on berry quality. The maximum total carbohydrates was recorded in vines sprayed with potassium sulphate and urea. Thus, spraying Thompson seedless grapevines twice with GAJ, urea and potassium sulphate were considered of promising treatment. | ||
