1. Topdressing nitrogen fertilization associated with trinexapac-ethyl on industrial quality of oat grains
ABSTRACT Nitrogen fertilization, besides increasing productivity, can favor the production of well-formed, large, and heavy grains, which are traits valued by the oat processing industry. However, high nitrogen (N) doses may lead to plant lodging, which could be solved by using growth retardant. This study aimed to evaluate the industrial quality of white oa

2. Paclobutrazol application in potted ornamental pepper
RESUMO Dentro da variabilidade genética no gênero Capsicum há plantas com grande potencial ornamental, mas com altura desconforme da exigida pelo mercado. A aplicação de paclobutrazol (PBZ), retardante de crescimento e inibidor das giberelinas, é uma alternativa para reduzir a altura das plantas. O objetivo foi avaliar o efeito de diferentes concentra�

5. Determinação da concentração de paclobutrazol por cromatografia líquida de alta eficiência e espectroscopia
Paclobutrazol is a plant growth retardant which is used world-wide for increasing the yield of cereal crops. However, this compound remains active in the soil for several years and can severely affect the growth and development of subsequent crops, mainly by reducing vegetative vigor. The aim of this work was to develop and validate methods for the determina

6. Effect of paclobutrazol on germination and metabolism of ethylene in seeds of Stylosanthes humilis H.B.K. / Efeito do paclobutrazol na germinação e no metabolismo do etileno em sementes de Stylosanthes humilis H.B.K.
Germination of non-dormant seeds of Townsville stylo (Stylosanthes humilis HBK), a tropical annual forrage legume was decreased by the growth retardant paclobutrazol (PBZ) [(2RS, 3RS)-1-(4-chlorophenyl)-4,4-dimethyl-2-(1H-1,2,4- triazol-1-yl)pentan-3-ol] suspensions. This effect was reverted by 2-chloroethylphosphonic acid, an ethylene-releasing substance, a

7. Nitrogen fertilization and growth retardants in wheat / Adubação nitrogenada e redutores de crescimento na cultura do trigo
The objective of this work was to study the effects of nitrogen fertilization and growth retardants on wheat (Triticum aestivum L.) crop. The study was conducted at the Experimental Station Prof. Diogo Alves de Mello, Federal University of Viçosa, Viçosa-MG (2045 S; 4251 W; 650-m altitude), in 2005 and 2006. Three experiments were carried out in a randomiz

9. Cultivo in vitro de Artemisia annua L. para a produção de artemisinina
Malaria, one of tbe major public health poblems in tropical countries, has been counteracted by syntbetic drogs such as chloroquine and their derivatives, presenting serious side effects. In addition their efficacy is affected mainly by the resistance of the malaria causing agent to these drugs. A plant extract from Artemisia annua, containing artemisinin, h

10. Plant Growth Retardants as Inhibitors of Sterol Biosynthesis in Tobacco Seedlings 12
Three plant-growth retardants 2′-isopropy1-4′-(trimethylammonium chloride)-5-methylphenylpiperidine carboxylate (Amo 1618), β-chloroethyltrimethylammonium chloride, and tributyl-2, 4-dichlorobenzylphosphonium chloride were tested for their effects on sterol production in, and growth of tobacco (Nicotiana tabacum) seedlings. As the concentration of each

11. Effects of Ancymidol (a Growth Retardant) and Triarimol (a Fungicide) on the Growth, Sterols, and Gibberellins of Phaseolus vulgaris (L.) 1
The effect of the two substituted pyrimidines, ancymidol (a growth retardant) and triarimol (a fungicide) on Phaseolus vulgaris was studied. Both compounds retarded shoot and root elongation as well as increases in fresh weight. Both compounds caused production of ethylene-like responses when given in high dosages or when applied shortly after germination. A
