Effect of Chilling and Gibberellin Spray on the Rosette-like Growth of Un-chilled Plants of Chrysanthemum. M. A. KHER, Masato YOKOI and Kiyoshi KOSUGI, Faculty of Horticulture, Chiba University, Matsudo, Japan. Tech. Bull. Fac. Hort. Chiba Univ. No.20: 25〜29, 1972. A study was conducted to find out the response of un-chilled suckers of chrysanthemum cultivar 'Otome Zakura' to chilling treatment and GA application. One set of non-chilled suckers was induced to resetted condition by growing at 10℃ minimum temperature under natural short-days from November onward. These resetted plants were then chilled for periods of 0, 10, 20, 30 and 40 days in the open in different batches. Half the number of plants in each batch were then sprayed with 100ppm GA solution (sprayed twice). Another set of suckers was planted on December 23, i. e. after they were sufficiently chilled by natural low temperature in the field. The results showed that after remaining in rosetted condition for about three months even the control non-chilled plants displayed rosette breaking tendency. Both chilling and GA, separately as well as in combination accelarated internode elongation and blooming. Thirty day chilling was found to be most effective. Early chilling resulted in earlier internode elongation and blooming. Further trials have been suggested to find out whether early GA application will have similar response as early chilling in this cultivar.
