2. Objectives
 Standardization of phenological monitoring
methods to track tree phenology of
horticultural fruit crops.
 To evaluate the response of tree phenology of
horticultural fruit crops to changing climate.
 To evaluate the best management practice for
manipulation of the climate change effect on
horticultural fruit crops.

9. BBCh Scale (Extended/Modified)
 BBCH-scale - to identify
the phenological development stages.
 BBCH officially stands for
"Biologische Bundesanstalt, Bundessortenamt
und CHemische Industrie".
 The abbreviation unofficially represents
Bayer, BASF, Ciba-Geigy and Hoechst.
