Study on improvement of the mulberry cutting propagation technique in nursery

Author
Abstract

With the current process of mulberry cutting propagation the multiplication coefficient is still low that can not meet the demand for seedlings. Therefore, the study on improvement of mulberry cutting propagation technique was conducted. As a result, by research on two new mulberry varieties S7- CB and VA-201 a number of technical measures were identified as follows: Short two bud cuttings are used instead of 4 bud cuttings. Growth age of cuttings is 6 months. The density of cutting growing in nursery for S7-CB and VA-201 is 100 cuttings /m2 and 67cuttings/m2 respectively. The amount of inorganic fertilizer suitable for nurseries is (6 N + 3 P2O5 + 3 K2O) kgs/100 m2 . Rooting stimulant α-NAA (with concentration of 2,000 ppm, treatment duration of 6 minutes) is used for short 6 month aged cuttings and young 4 month aged cuttings.
