Development of an in vitro rooting bioassay using juvenile phase stem cuttings of persea americana mill

, : Development of an in vitro rooting bioassay using juvenile phase stem cuttings of persea americana mill. Journal of Horticultural Science 63(2): 295-302

A rooting test was developed with shoot cuttings taken from aseptically germinated avocado seed. The rooting required treatments in two steps: (1) three days in a medium containing indole-3-butyric acid (IBA) (25 mg l-1) and (2) four to eight weeks in an auxin-free medium. Rooting was accomplished with both media containing 0.3.times. strength Murashige and Skoog salts, 3% sucrose, 0.4 mg l-1 thiamine hydrochloride, 100 mg l-1 i-inositol, and 0.8% 'TC' agar. The auxin-free medium also contained 1 g l-1 activated charcoal.

Etiolation, bark ringing and application of auxins (IBA and NAA) were used in different combinations. Etiolation alone gave 22.5 and 25.0% of rooted cuttings in Colin V-33 and Fuerte, respectively. Etiolation + bark ringing gave 60.0 and 62.5% of...

Cuttings of 10 different clones of avocado (P. americana Mill.) were rooted under intermittent mist. A wide range in rooting capability was noted. Rooting percentage of clones was correlated with number of leaves retained on the cuttings. Speed of...
