(During the Period of 2019-2023)

Mango

  1. Quarantine hot water treatment (HWT- 48°C for 60 minutes) caused severe  internal break down during storage (RT, 8 and 13°C) in Alphonso cultivar of mangoes but not in Banganapalli.  Integration of quarantine HWT (48°C for 60 minutes) with fungicidal HWT (55°C for 10 minutes) did not affect the quality of  Banganapalli mangoes stored at RT.
  2. Hot water treatment (55°C for 5min) prior to quarantine irradiation treatment (400 Gy) did not have any adverse effect on the internal quality of Alphonso mango and  helped in control of anthracnose spoilage during 12 days at RT and 4 weeks at 13°C
  3. Alphonso mango fruits  subjected to HWT at 50 °C for 40 min followed by + 5 % salt  dip for 30 min showed  control of fruit fly (98.2%)  without causing  any internal breakdown & also controlled anthracnose spoilage

Guava

  1. Among different ethylene inhibitors, 1-MCP was found to be more beneficial in extending the green  life of guava for 1 week at RT; 3 weeks at 12°C and 4 weeks at 8°C. Integration of MAP (non-perforated PP film or  PD 961 films)  with -1MCP treatment helped in  lowering the weight loss and  and maintenance of  nutritional quality Fig
  2. Optimum temperature for Fig (cv. Poona) was found to be 5°C with 10 days storage life compared to 2 days at RT. The storage life was 1 week at 13°C and 8 days at 10°C
  3. Fig (cv. Poona) harvested at turning stage (25% and 50% colouration) could be stored for 2 weeks at 5°C,  10 days at 10°C, 1 week at 13°C and 3 days at RT
  4. Storage life of figs harvested at 25% colouration could be  further extended to  4 days at RT, 2 weeks at 10°C and  4 weeks at 5°C with 500 ppb 1-MCP treatment

Jamun

  1. Optimum temperature for storage of Jamun was found to be 8°C where they could be stored for 10 days  compared to1 week at 13°C & 20°C.

Brinjal

  1. Optimum temperature for Brinjal (Mangari gota type) was found to be 7°C with a storage life of 3 weeks with less weight loss and without shriveling compared to 2 weeks at 10°C and 10 days at 13°C.

Muskmelon

  1. Optimum temperature for muskmelon was 10°C with 2 weeks  storage life. The storage life of could be further extended to 25 days with 500 ppb 1-MCP treatment and 3 weeks   with 1% Chitosan or 3mM SA or  1.5  mM SNP treatments at 10°C 

Water melon

  1. Watermelon fruits cv. Arka Shyama could be stored for 3 weeks at 10°C with acceptable sensory qualities as compared to 16 days at 13°C and 10 days at room temperature
