2006. The two-year yield difference may result from the
difference of weather condition such as ET0 and rainfall.
3.4. Fruit quality
It should be noted that ADI improved the fruit Vc content by
15.3–42.2%in both years, but decreased the fruit TA by 13.2% at
the same level of TSSC compared to CDI, therefore increased
TSSC/TA by 22.5% at post-veraison in 2005. On the other hand,
the results also showed that ADI improved TSSC at the similar
level of TA with highest TSSC/TA significantly at harvest in
2006 (Table 5). The two-year fruit quality difference is resulted
from the growth stage under different weather conditions.
