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 ( ) and black plum () was Cordia myxaSyzygium cumini 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.
