Changes in some Biochemical Parameters of Ivy Gourd (Coccinia Indica Wight and Arn.) Fruits after Infection of Fruit Rot

Vaishali Sidram Chatage and Udhav Narba Bhale

Biochemical changes were observed from healthy and artificially inoculated carbendazim resistant (Ap13) and sensitive (Ap11) isolates of Ivy gourd (Coccinia indica) fruit caused by Alternaria pluriseptata (Karst & Har). There was a significant variation between healthy and infected fruit which showed significant changes with respect to estimation of ash content, total sugar, reducing sugar, non reducing sugar, starch, polyphenol, total ash, Nitrogen, Phosphorus, DNA, RNA, Calcium, Iron, Magnesium, Zinc, Manganese and crude protein. Among them, total sugar (35.4 mg/g) was increased in healthy fruits. But in Polyphenols (17.401 mg/100gm) it was decreased in healthy fruits as compared with infected fruits followed by starch (15.00 mg/g) and others. Infected fruit of C. indica by both resistant and sensitive isolates reduced the contents of all parameters. This was more pronounced due to utilization of nutritious compounds of the fruits by fungal pathogen for their growth and metabolism which causes deterioration of the nutritious compounds of the fruits.
