Effect of Weather Condition on Vegetative Propagation of Black Plum (Syzygium cumini) and Glue Berry (Cordia myxa)

The experiment on effect of growing season on propagation of glue berry (Cordia myxa) and black plum (Syzygium cumini) was conducted at the regional research station, CCS Haryana Agricultural University, Hisar during 2017–2023. There were two treatments i.e., time of planting (eight months i.e., February to September) and method of propagation. The maximum success rate of budding 63.3 % was during August and July in black plum and glue berry, respectively over the years. The per cent success rate of soft wood grafting was maximum 53.3 and 56.3 % in August and July in black plum and glue berry respectively. However, in black plum lowest budding and soft wood grafting success was as 10.0 % in February, 2017–23. Similarly, in glue berry minimum budding and soft wood grafting success was 13.3 % in February. Positive and significant correlation existed between percent success budding with minimum temperature (r=0.826) while a negative and significant correlation existed between percent success budding with sun shine hours (r= -0.808) in black plum and glue berry. There was non-significant correlation existed between percent success soft wood grafting with maximum temperature, humidity, rainfall and evaporation weather parameters.
