WebFeb 23, 2024 · In vitro culture is still the most popular method, but it is hampered by low efficiency and high time expenditure, and its applicability is restricted to a few species. However, in vivo approaches that trigger the development of a haploid embryo in the plant hold great promise to overcome these limitations. WebUnfertilized cotton ovules, cultured in vitro, produced fiber in re-sponse to indoleacetic acid (IAA) and/or gibberellic acid (GA3). Of the two hormones, IAA produced the greater amount of fiber per ovule, and the effect of both hormones applied simultaneously was approximately additive. Depending upon in vitro culture temperature, a variable num-
