| Abstract | ||
| This study was carried out during the cultivation season 2004 in Abu-Al Khassieb location to determine the effect of growth regulator GA3 with different concentration on some fruits features of Hillawi cv. at at two dates (1/6& 1/7 ) . This study explained that the fruit spraying with GA3 at the first date led to decrease fruits weight average ; while the spraying with GA3 concent.75ppm at the second date led to increase the weight of fruit significantly &reached 6.78 g in contrast with untreated fruits. The results, also showed that the spraying with all concentration of GA3 for each dates led to increase the water content significantly in the fruits of Hillawi cv & led to decrease the rate of fruit ripening . The results proved that GA3 concentration spraying at all dates led to reduce the white end percentage with physiological damages ,this reducing was correlated positively with the increasing of concentration .the lowest percentage of white end was in the treatment of 75ppm which was 15.12 & 14.07 % for each dates respectively in contrast with un treatment fruits 27.47% . | ||
