Physicochemical characteristics of fruits of eight ber (Ziziphus
mauritiana ) varieties, Chhuhara, Gola, Elaichi, Kaithli, Nazuk, Sanaur
2, Umran and ZG-2 in relation to fruit fly infestation were studied at
Abohar. Fruit fly (Carpomya vesuviana ) infestation was positively
correlated with fruit weight, pulp-stone ratio, total soluble solids
(TSS) and total sugars, whereas, it was negatively correlated to
acidity, vitamin C [ascorbic acid] and total phenols. The varieties high
in pulp content, TSS, total sugars, low acidity, vitamin C and total
phenols were highly susceptible to fruit fly attack. The most
resistance varieties were Umran (49% incidence), Gola (40%) and ZG-2
(33%). |
