“…Statistical analysis did not show any explicit effects of a dose of the growth regulator, although kinetin or IPO-1 tended to cause increased roots, while higher doses of other growth regulators tended to result in decreased roots length and diameter. Similar results were obtained by El-Keltawi et al (1996) after daminozide application, studies performed on Chrysanthemum roots. In these experiments roots dug from plots treated with growth regulators were characterized by shorter total length and were thinner than the ones on the control object (the lower dose of benzimidazole derivative was the exception).…”

“…The higher dose of daminozide or IPO-1 caused a decrease in dry weight of aerial parts and their morphological parameters were also examined ( Table 2). In floristry, daminozide is usually used for stems shortening (El-Keltawi et al 1996;Startek 1997), but in the case of ginseng, a significant increase in stem height was observed. Our result is similar to that observed in the culture of sweet basil (Mahmoud 1996).…”

American ginseng (Panax quinquefolium L.) is a perennial medicinal herb originally grown in Canada and USA, and recently also in China, Australia, Holland and Poland. Several commercial preparations are produced from ginseng roots, that are known for their antifatigue, antitumor, antistress and immune system stimulating functions. The medicinal properties are due mainly to the active components -ginsenosides. In this work, the results of field cultivation experiments are presented that examine the effects of foliar application of several growth regulators on quality parameters and ginsenoside content of P. quinuefolium roots. The growth regulators tested, i.e., kinetin, daminozide, mixture of gibberellic acid (GA 3 ) with potassium salt of a-naphthalene acetic acid (kNAA) and new preparation -IPO-1 -benzimidazole derivative (obtained from the Institute of Organic Industry in Warsaw -at present during the process of patent), were applied at a concentration of 100 or 200 mg l À1 in the middle of June in the 2nd year of vegetation. After 4 years of cultivation, the roots were dug up and dried, and subsequently the quantitative analysis of individual saponins (R b1 , R b2 , R c , R d , R e , R g1 ) by HPLC was performed. Growth regulators significantly affected quality parameters, morphological features and accumulation of individual and total ginsenosides in ginseng roots. Regardless of doses, the plant roots treated with growth regulators had a higher content of total ginsenosides in comparison to the control. The growth regulators also affected individual ginsenosides level and narrowed the ratio of R b :R g group. The application of kinetin, daminozide and benzimidazole derivative for foliar spray during 2nd year of American ginseng vegetation caused a significant increase in air dry weight of roots and aboveground parts whereas the mixture of GA 3 and kNAA showed a decreasing effect. An increase of roots size was observed using higher doses (200 mg l À1 ) of kinetin and daminozide while a decreasing tendency appeared with the application of the other preparations.

“…Diameter of inflorescences remained almost same in all the plants irrespective of any treatment (Table 3). The B-nine application has also been shown to be ineffective on flowering characteristics of Chrysanthemum morifolium (El-Keltawi et al, 1996). During the course of present investigation the use of these retardants resulted in the early emergence of buds and inflorescences (approximately 10 days earlier) in plants treated both with cycocel and B-nine as compared to the distilled water and Tween controls.…”

“…However the desired effects of cycocel and B-nine (chemical tailoring) were not registered in the present cultivar. The present study suggests that the treatment effect may be cultivar dependent, as many other cultivars of chrysanthemums have been chemically tailored with desired effects using cycocel and B-nine (Wilfret, 1991;El-Keltawi et al, 1996;Saikia and Talukdar, 1997;Mahalle et al, 2001; Navale et al, 2010;Patel et al, 2010;Alhajhoj, 2017). In the light of available literature and on the basis of r esul t s obt a i ned in t he presen t st udy i t m a y be concluded that the desired effects of PGRs on the display value of ornamental plants are dependent on the type and dose of a particular PGR, time and method of application and more importantly the species and cultivar of the ornamental plant.…”

An experiment was conducted to study the effect of graded concentrations of foliar applied growth retardants (cycocel and B-nine) on the growth and flowering of Chrysanthemum morifolium cv. Flirt. Uniform rooted cuttings raised in pot soil culture received spray applications of growth retardants viz., cycocel and B-nine prepared in 0.1% Tween 80. Cycocel was applied at 1000, 2500 and 5000 mgL -1 , whereas B-nine was applied at 100, 250 and 500 mgL -1 concentrations. Plants were sprayed at 2 and 6 weeks after transplantation. Visual observations, plant height, fresh mass, dry mass, number of laterals, number of inflorescences and inflorescence diameter were recorded at periodic intervals. Cycocel treated plants recorded a significant increase in fresh and dry mass of whole plants, leaves and roots, whereas B-nine treated plants were comparable with the controls. Cycocel and B-nine treated plants showed early emergence of buds and inflorescences, whereas no significant effect was recorded on number of laterals. Cycocel application resulted in the increase in inflorescence number. The present results suggest that the treatment effect may be cultivar dependant as many other cultivars of chrysanthemums have been chemically tailored with desired effects using cycocel and B-nine.

Produção de crisântemo (Dendranthema grandiflora Tzvelev.) 'Snowdon' em vaso II: ciclo da cultivar... Ciência Rural, v.34, n.6, nov-dez, 2004. Ciência Rural, Santa Maria, v.34, n.6, p.1709-1714, nov-dez, 2004 ISSN INTRODUÇÃOO crisântemo de vaso é uma das principais flores produzidas em estufas e com constante aumento de produção. Isso ocorre devido à cultura apresentar principalmente grande diversidade de formas e cores das inflorescências, precisão da resposta ao fotoperíodo e longevidade das inflorescências.No Rio Grande do Sul, a principal espécie de vaso cultivada é o crisântemo, cuja produção é insuficiente para atender o mercado. Uma das causas dessa deficiência é devido às limitações térmicas e de radiação, especialmente no inverno, o que dificulta a produção contínua. Embora o mercado apresente um grande número de cultivares de vaso, essas ainda não o satisfazem quanto a adaptabilidade para o cultivo em regiões de invernos frios, especialmente as do tipo bola. Segundo BELLÉ (1998), as cultivares do tipo bola de corte podem ser conduzidas em vaso, desde que, o manejo dos redutores de crescimento seja equacionado.As cultivares de corte tipo bola 'Snowdon' e 'Yellow Snowdon' não apresentam limitações térmicas na produção durante o ano todo no Rio Grande do Sul. Por essa razão, seu cultivo em vaso pode se tornar um produto diferenciado, permitindo uma melhor comercialização.A cultivar Snowdon é classificada como: tipo encurvado ou bola, ciclo longo (9 semanas) e cor Recebido para publicação 28.07.03 Aprovado em 05.05.04
