In the recent paper genotoxic effects of daminozide and its metabolites were tested. Evaluation of the mutagenic effect of daminozide was by: (i) the Salmonella/mammalian microsome Ames test with S.typhimurium TA97, TA98, TA100 and TA102. (ii) E. coli PQ37 strain to reveal an induction of the SOS response, (iii) S. typhimurium TA1538 (uvrB) and TA1978 (uvr+) to detect the chemicals bound covalently to DNA (repair test). Daminozide was not mutagenic in any of the S.typhimurium strains and did not induce damages in DNA recognized by correndonuclease II, as shown by the repair test. Only metabolites of daminozide induced the SOS system.

This study evaluates the effects of the two gibberellin inhibitors (daminozide, prohexadione-calcium) on certain growth and anatomical characteristics of coriander (Coriandrum sativum L.). Both growth retardants were found effective in reducing stem elongation; that response varied with the concentration used. Prohexadione-Ca at 200 mg l-1 reduced height by 38%. Coriander fruits were heavier after the application of prohexadione-Ca, but this did not translate to increased fruit yield or fruit essential oil yield. Prohexadione-Ca induced precocious anthesis (3-5 days earlier). Both prohexadione-Ca and daminozide apparently affected leaf and stem anatomy. Generally, retardant-treated plants possessed thicker leaves, wider stems with more collenchyma tissue, and more vessels in the vascular bundles. Chlorophyll fluorescence measurements disclosed a decrease in the photochemical efficiency of PSII in retardant-treated plants as compared to the controls. The chlorophyll fluorescence parameters Fv/Fm and Fv/Fo can provide a tool for early diagnosis of the use of growth retardant even before any signs of growth retardation are visible in the plants.

The experiment was conducted to inhibit the growth of dwarf alstroemeria cultivars 'Rosalina' and 'Dorotea' using flurprimidol and daminozide. Additionally, the effect of these retardants on days to anthesis, flowering shoots number, diameter and longevity of florets was evaluated. In vitro propagated plants, grown in 12 cm pots were treated with single sprays of flurprimidol (7.5,15,22.5 mg l-l) and daminozide (2500, 3500, 4500 mg l-l) following second pruning, when shoots were 9-12 cm long. Well retarded plants of both dwarf alstroemeria cultivars were obtained when plants were sprayed with tlurprimidol at 22.5 mg l-l. Plants treated with daminozide at all tested concentrations were to tall to be grown in 12 cm pots. Flurprimidol significantly reduced the canopy diameter, number of tlowering shoots of alstroemeria cultivars . Rosalina ' and . Dorotea' and floret size of culti var . Rosalina' . Daminozide had no effect on the number of days to flower but flurprimidol delayed tlowering of tested cultivars only at concentration of 22.5 mg l-l. Intensified green leaf colour was observed on tlurprimidol treated plants. The chemical names used: a-(1-methylethyl)a-E 4-(tritluoromethyloxy )-phenyl]- 5-pyrimidine-methanol (flurprimidol), butanedioic acid mono (2,2-dimethylhydrazide) (daminozide).

Oceniono skuteczność daminozydu w 6 terminach uprawy gałązkowej odmiany chryzantemy wielkokwiatowej (Chrysanthemum × grandiflorum /Ramat./Kitam.) ‘Breeze’ z grupy Santini. Rośliny uprawiano w szklarni od 1 kwietnia, 1 maja, 1 czerwca, 1 lipca, 2 sierpnia i 1 września 2004 roku, przez 3 tygodnie przy dniu długim (16 godzin). Następnie sadzono je do szklarni krótkiego 10-godzinnego dnia. W każdym z terminów uprawy „gałązki” o szypułach długości 2-3 cm potraktowano daminozydem (1275 mg‧dm⁻³), opryskując górne liście roztworem B-Nine 85 SP. W cyklach od sierpnia i od września rośliny kwitły z 1-2 dniowym opóźnieniem. Rośliny opryskane retardantem były nieznacznie niższe od nietraktowanych, zwłaszcza sadzone w późniejszych terminach. Wysokość, jaką osiągnęły w cyklach od kwietnia do lipca, spełniała wymogi I wyboru, a w sierpniu i wrześniu II wyboru. „Gałązki” pod wpływem daminozydu zmieniły pokrój, szczególnie w cyklach rozpoczynanych w czerwcu, w sierpniu i we wrześniu. Szypuły wyrastały bliżej wierzchołka pędu, tworząc nieco węższe, bardziej wyrównane „gałązki”. Liczba koszyczków kwiatowych i ich średnica nie uległy zmianie.
