Abstract:

Aiming at the occurrence of seed dormancy in newly harvested ‘Cuixue 5’ muskmelon, the seed germination test was conducted by automatic dormancy breaking, high-temperature treatment, low-temperature freezing treatment and exogenous hormones treatment, to explore efficient ways to break seed dormancy of ‘Cuixue 5’ muskmelon, thereby increase the germination rate. The results showed that the dormancy release of ‘Cuixue 5’ seeds mainly relied on the automatic dormancy breaking process, and high-temperature treatment could accelerate the process. In addition, low-temperature freezing and exogenous NAA and GA3 treatment could not break seed dormancy of ‘Cuixue 5’ and increase the germination rate; while exogenous 6-BA could significantly promote seed germination on the basis of prolonging the germination time.

Key words: thick-skinned muskmelon, ‘Cuixue 5’, seed, dormancy breaking, seed germination rate
