| Plant lodging in wheat has been controlled through growth retardants. However, there is lack of information on the effect of these products on the physiological quality of seeds. The objective of this study was to evaluate the physiological quality of wheat seeds obtained under different rates and application times of three growth retardants. The trial was carried out in Viçosa-MG, from May to September 2005, in a factorial and hierarchical scheme, in randomized block design with four replications and a control treatment. The treatments consisted of 500, 1000 and 1500g ha-1 of chlormequat; 40, 80 and 120g ha-1 of paclobutrazol and 62.5, 125 and 187.5g ha-1 of trinexapac-ethyl applied at the 6 or 8 growth stage based on the scale of Feeks and Large, and a... |

| Objetivou-se neste trabalho estudar os efeitos de um regulador de crescimento (paclobutrazol) sobre o crescimento e a produção de flores de girassol em vasos, crescidos sob sistema hidropônico. Foram utilizados dois genótipos de girassol (BRS Oásis e Helio 358), combinados com seis doses de paclobutrazol (0;0,5;1;2;4 e 6 mg.L-1) e substrato inerte de sílica moída. A solução nutritiva foi a de Hoagland modificada (EPSTEIN & BLOOM, 2004) e as plantas foram mantidas sob aeração constante. Para avaliar os efeitos do paclobutrazol sobre o crescimento das plantas (altura final e diâmetro de capítulo), as variáveis foram submetidas à análise de variação (teste F), utilizando-se rotinas do sistema SAS/STAT , aplicando-se, para os valores significativos a... |

| ABSTRACT The consumer's constant search for novelties in the area of ornamental plants has inspired the use of species that are normally used for other purposes, such as fruit-bearing plants, to be introduced into floriculture. The physalis, a fruit-bearing plant, with a beautiful accrescent fruiting calyx that envelops the berry, can be used for these purposes. However, this plant can reach 70 cm high, which makes it unviable to be used as an indoor plant. The objective of this research was to decrease the size of the physalis (Physalis angulata) for ornamental use, pot it and apply the plant growth regulator Paclobutrazol (PBZ). The PBZ growth regulator was applied only once, via foliar spray at the concentrations of 0, 30, 60, 90, 120 and 150 mg a.i L-... |
