Abstract/Description: | Gibberellins are known to substitute for long-day requirements in some plant species and short day can not be replaced by gibberellins. Various workers have tried gibberellin-containing mixtures to induce flowering. In the sub-tropical plains of India, flowering could be induced in some genotypes using extended photoperiod and gibberellic acid (GA3) containing mixtures with auxin (2,4 D), and with auxin (IBA) and cytokinin (kinetin). GA3 in combination with Gapol (a mixture of various compounds including the auxin indole acetic acid) was found beneficial in flower development in a non-flowering cultivar Marijke in Mexico. Gibberellic acid (GA3) has also been used in enhancing flowering in normally flowering genotypes. Flowers induced by various workers using GA3-containing treatments, however, were in many cases either sterile and/or did not set berries. The flower sterility observed may be due to hormonal imbalance. In the Indian sub-tropical plains silver thiosulphate (STS) in combination with extended photoperiod has been reported to be useful in inducing fertile flowers in non-flowering genotypes followed by good berry setting. This treatment was also found useful in enhancing flowering in normally flowering genotypes. The increase in flowering by STS was due to both an increased number of inflorescences and an increased number of flowers per inflorescence. |
