Effects of BA Treatment on Growth and Flowering of Some Vegetative Lines of Gypsophila paniculata L. ^|^lsquo;Bristol Fairy^|^rsquo;
Year: 1989
Type: article
Abstract: Application of 300ppm BA (6-benzylaminopurine) promoted flower initiation and advanced blooming by about half a month in a heated plastic house under long-day conditions in BF-04, BF-08 and BF-13 vegetative lines of Gypsophila paniculata L. ‘Bristol Fairy’, but not in BF-20 line. BA treatment also promoted flowering in BF-08 and BF-13 lines even when grown in an unheated plastic house under nutural daylength. BA treatment seemed to substitute for chilling for the induction of flowering, and consequently plants treated with BA overcame unfavorable growing conditions.On the other hand, GA3 (gibberellic acid) did not promote flower initiation in any lines grown in an unheated plastic house under natural daylength.Thus, cut flower production of gypsophila from autumn to winter is possible even in an unheated plastic house under natural daylength by the selection of vegetative lines with low chilling requirement such as BF-08 or BF-13, and the application of BA.
