Abstract
For rooting alfalfa cuttings the application of 350 p p m. naphthalene acetic acid in talc, followed by culturing the treated cuttings in embedding medium made of 1 part sand plus 1 part sphagnum peat by volume, has given good results Duplication of the chromosomal set may be successfully achieved by soaking seedlings in an inverted position in 0 07 per cent aqueous colchicine for 6 hours at room temperature. A similar procedure may be applied to rooted cuttings. Efficient emasculation may be effected by immersing opened flowers for 4 to 6 seconds in 57 per cent alcohol followed by soaking in water for 15 to 30 minutes Anthers may be removed by sharp blasts of breath instead of suction by air nozzle.
