different parts of six species of the Annonaceae family were evaluated
against adult worms and egg masser of Biomphalaria glabrata, extracts
posses properties lethal to Biomphalaria glabrata (Dos Santos and Sant Ana,
2001).
Effect of seed extract of Annona squamosa on digestive enzymes were
examined at sublethal dose. The inhibition of amylolytic, proteolytic and
lipolytic enzymes in the gut regions of beetic indicates the utilization of these
enzymes for energy production (Kuruppasamy et al., 2001).
Three new tetrahydrofuran ring acetogenins were reported to have selective
cytotoxic activity against human pancreatic tumor cell lines PACA-2 (Hopp
et al., 1997; Hopp et al., 1998).
TRADE AND COMMERCE
Bulk of the crop is harvested mostly from the wild plants in Andhra Pradesh.
The harvested crop is gathered at different centres and finally transported. It
is commercially important plant next to mango, banana, jack fruit and citrus
fruits. No proper gradation is done but some dealer grade and pack the fruit at
the top. Fruits are sold in lots but no systematic market exist. Since the fruits
are perishable easily the packing is done in ventilated boxes for trade
(Anonymous, 1985).
Retail market price – Fruits – Rs. 40-60/- kg; Seeds- Rs. 60/- kg (2006).
SUBSTITUTES AND ADULTERANTS
Several hybrids or cultivars of this plants; A. cherimda, A. reticulata, A.
glabra etc. are used as substitute (Anonymous, 1985).
PROPAGATION AND CULTIVATION
The plant can be cultivated on different types of soils viz. loamy, light, sandy,
rocky, etc. It is mostly propagated by fresh seeds, germinated on raised beds.
One-year-old seedlings are transplanted in pits at the distance of 4-6 m. after
which, they can survive on natural rainfall. The plants do not require frequent
irrigation, whereas the maximum yield can be obtained when there is rainfall
of 50-75 cm. The plants can tolerate temperature of 40�C and the drought
conditions.
The tree starts flowering from March – July and fruits matures from August-
January. It is always better to harvest when fruits show signs of cracking. An
individual tree grown on ordinary soil and in natural conditions, bears 50-100
fruits. An average yield per hectare is reported to be 6600 kg. (Anonymous,
1985).
