with reflective mulch contained up to 2.4% (from 13.3-15.7%) more sugar
than those of the control (uncovered grass alleys).
15.5.2 BLUEBERRY
In general, high temperatures during blueberry harvest season hasten rip-
ening. Heavy rains during periods of high temperature can further has-
ten ripening, cause splitting, and greatly reduce storage quality. Overripe
blueberries are extremely susceptible to damage.
15.5.3 AONLA
In arid region of Bikaner, aonla fruit is generally harvested before severe
winter but fruit of late varieties gets affected by chilling temperatures in
January. Fruit becomes whitish in color with oozing of water and then it
becomes dry and black (More and Bhargava, 2010). Frost affected fruit
has no shelf life as the secondary infection starts immediately.
15.5.4 BER
Fruits are susceptible to chilling temperature and frost and losses are high-
er in years where continuous low temperature persists (More and Bhar-
gava, 2010). Cultivars Sanaur-5, Syriya and Tikkadi showed tolerance to
frost, Umran and Mundia were found to be susceptible while Sanaur-1,
Kathaphal and Jogia were moderately affected. Frost damaged fruits are
shriveled, brown and turn black afterwards.
15.5.5 AVOCADO
Changes in climate will affect avocado fruit quality and storage abil-
ity also. Avocado fruit shape is influenced by temperature and humidity.
Cooler climate tend to make fruit rounded while high temperature with hu-
midity causes fruit to be elongated (Arpaia et al., 2004). After mild freezes
in California, avocado fruit exposed to chilling temperature had more de-
cay, chilling injury and weight loss following storage. Increased tempera-
