| Abstract:
In Chile, area planted to pears increased dramatically in the last decade, reaching 17.000 ha in 1994. Several problems arised parallel to this increase, which has contributed in different degrees to discard annually over 30% of pear produced for export due to non-compliance of quality standards. Among these problems are: inadequate geographical distribution of varieties; low yield per hectare due to biennial production and natural fruit drop; low precocity; russet incidence; inadequate pollinizer selection; severe winter pruning (which along with excessive N-fertilizer use, generates high vegetative growth); bruising; sunburn; European canker; variety/rootstock incompatibility and postharvest softening and rotting. All the above, along with in decrease in international fruit prices and excess fruit in the markets, has caused low crop profitability. Finally, a notorious lack of local research aggravates the prospects of this fruit crop. | |
