The effect of various growth regulators on the atrophy of terminal flower buds was tested on Baccara roses. Treatments with gibberellic acid (GA) and 2-chloroethyl trimethyl ammonium chloride (CCC) reduced the atrophy of the flowers. The application of 2-chloroethyl phosphonic acid (CEPA) to the buds enhanced abortion, and the effect was more marked on the lower than on the upper shoot. The stage most sensitive to CEPA was when the shoots were 8-35 cm long. Treatment with abscisic acid (ABA) had no effect of the degree of "blindness", nor did kinetin applied to the apex affect flowering. Spraying with benzyl adenine increased both the rate of sprouting of the lateral buds and the extent of "blindness" of the sprouting shoots, but did not reduce the number of flowers per branch.

“…Also the growth of the stem in Narcissus [13], the inflorescence stalk in Hyacinthus orientalis [19], and the scape in Hippeastrum [20] are hormonally controlled by auxin. Ethylene or sources of ethylene (2-chloroethylphosphonic acid -ethephon) applied to intact tulip plants cause many disorders, including flower bud blasting [21][22][23][24][25][26]. Consequently, auxin production by and transportation from the gynoecium will be decreased and ultimately stop.…”

Hormonal regulation of the growth of leaves and inflorescence stalk in Muscari armeniacum Leichtl.

et al. 2016

It is known that chilling of Muscari bulbs is necessary for the growth of the inflorescence stalk and flowering, but not for the growth of leaves. Gibberellic acid (GA) accelerated stem growth and flowering in chilled Muscari bulbs. In the present experiment it was shown that in unchilled derooted Muscari bulbs the growth of leaves, but not the growth of the inflorescence stalk, was observed when bulbs were stored in water, GA at a concentration of 50 and 100 mg/L, benzyladenine (BA) at a concentration of 25 and 50 mg/L, or a mixture of GA+BA (50+25 mg/L), but abscisic acid (ABA) at a concentration of 10 mg/L greatly inhibited the growth of leaves. In chilled derooted Muscari bulbs the growth of leaves and inflorescence stalk was observed when bulbs were stored in water or GA, but BA and GA+BA treatments totally inhibited the growth of the inflorescence stalk without an effect on the growth of leaves. These results clearly showed that the growth of leaves and inflorescence stalk in Muscari bulbs are controlled by plant growth regulators in different ways. ABA totally inhibited the growth of leaves and inflorescence stalk in chilled derooted Muscari bulbs. It was shown that after the excision of the inflorescence bud in cultivated chilled Muscari bulbs, the inflorescence stalk died, but application of indole-3-acetic acid (IAA) 0.5% in the place of the removed inflorescence bud induced the growth of the inflorescence stalk. IAA applied under the inflorescence bud inhibited the development of flowers (flower-bud blasting) and induced the growth of the inflorescence stalk below the treatment site. These results are discussed with reference to hormonal regulation of stem (stalk) growth in tulip, narcissus, hyacinth, and Hippeastrum.

“…It is a result of the cessation of the development of the flower bud, and in the worst case, the deterioration of the flower bud. This disorder shows a range of symptoms from shriveled floral organs to wilted, papery and discolored leaves (De Munk 1973). Unsuitable temperature regimes during the period of bulb management (De Munk and Hoogeterp 1975;Le Nard and De Hertogh 1993) and exposure to ethylene (De Munk 1973;De Munk and Hoogeterp 1975;Moe 1979) give rise to this disorder.…”

Water deficit imposes stress on the young shoot located inside (Van Kilsdonk et al 2002) and is the cause of increased ABA level (Upreti et al 1997/98;Lopez-Carbonell et al 1994), which in turn results in a weakened sink of the flower bud.…”

Endogenous free IAA was examined with an immunohistochemical method for its involvement in the reduction of bud deterioration after GA 3 was injected into the bulbs. We found that tulip bulbs stored at 20°C constantly developed severe bud deterioration, whereas the symptoms of deterioration was lighter in the bulbs with GA 3 injection and not observed in the bulbs with 4°C treatment. 73% success in overcoming bud deterioration was achieved in 20°C with GA 3 treatment after 8 weeks of bulb storage, and the success rate was 7% after 12 weeks of storage. IAA was detected in the parenchyma cells in the internodes of the shoot after the bulbs were stored at 4°C or at 20°C with GA 3 injection for 4 weeks, but little was detected in the bulbs stored at 20°C constantly. Moreover, a weak IAA signal was present in between the cells of the internodes irrespective of bulb treatment. After planting, the bulbs that had been treated differently exhibited different flowering ability. The bulbs stored at 4°C for 4, 8 and 12 weeks attained high flowering percentage, which was lower in the 20°C with GA 3 treatment and lowest in the 20°C treatment. It may be concluded that GA 3 injection decreases bud deterioration of tulip bulbs during dry storage at 20°C by promoting the endogenous IAA in the internodes.
