1. Influência de diferentes doses de Fósforo e Potássio nos aspectos morfológicos, fisiológicos e na produtividade de plantas de soja tratadas com ácido 2,3,5 - triiodobenzóico / Influence of different doses of Phosphorus and Potassium on morphological, physiological and yield of soybean plants treated with 2,3,5 triiodobenzoic acid
Este trabalho teve como objetivo avaliar a influência de diferentes relações de fósforo (P) e potássio (K) nos aspectos morfológicos, fisiológicos, e nos parâmetros produtivos de plantas de soja tratadas com o retardador de crescimento TIBA, através da análise das variáveis altura, número de ramificações (primárias, secundárias e total), mass

2. 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

3. InfluÃncia da adubaÃÃo nitrogenada e de etil-trinexapac no crescimento e produtividade do trigo / Influence of nitrogen and plant growth regulator in growth and productivity of wheat
O trigo à uma cultura de alto risco, devido Ãs condiÃÃes ambientais e a incidÃncia de outros fatores como pragas, doenÃas e acamamento. Este Ãltimo à responsÃvel por perdas considerÃveis de grÃos, uma vez que dificulta muito a colheita, ocorrendo perda de produÃÃo e qualidade do produto colhido. Dessa forma, o presente trabalho procura demonstra

4. Influence of growth retardant and density on growth, yield and bending of soybean plants / InfluÃncia de retardante vegetal e densidade de plantas no crescimento, componentes da produÃÃoo, produtividade e acamamento na soja
A soja apresenta notÃria importÃncia na cadeia nacional de produÃÃo de grÃos, atualmente à o principal produto agrÃcola brasileiro justificando investimentos em tecnologia visando o aumento da produtividade e reduÃÃo dos fatores adversos à cultura. Assim, o presente trabalho se propÃe a avaliar o efeito da utilizaÃÃo de retardante vegetal em dif

5. Regulation of Plant Morphology by Growth Retardants: Effects on Phytohormone Levels in Soybean Seedlings Determined by Immunoassay
The effects of the growth retardants tetcyclacis, a norbornenodiazetine, and LAB 150 978, a dioxanylalkenyl triazole, on seedling growth and endogenous levels of phytohormone-like substances in Glycine max L. cv Maple Arrow were studied. The levels of phytohormone-like substances in the root and in the various shoot tissues were analyzed by immunoassay. Afte

6. 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

7. Ethylene Production by Sunflower Cell Suspensions 1: Effects of Plant Growth Retardants
From a variety of undifferentiated plant cell suspensions, 2,4-dichlorophenoxyacetic acid-dependent cells of sunflower (Helianthus annuus L. Spanners Allzweck) produced large quantities of ethylene. The maximum rate was about 1 nanomole × gram fresh weight−1 × hour−1 during the exponential growth phase. The action of various compounds known to interfer

9. Gibberellin A1 is required for stem elongation in spinach.
The effects of the growth retardants 2'-isopropyl-4'-(trimethylammonium chloride)-5'-methylphenyl piperidine-1-carboxylate (AMO-1618) and calcium 3,5-dioxo-4-propionylcyclohexanecarboxylate (BX-112) on stem elongation were investigated in the rosette plant spinach (Spinacia oleracea L.) under long-day (LD) conditions. Stem growth induced by a LD treatment wa

10. Incorporation of 14C-Kaurene into the Gibberellin of a Higher Plant (Pharbitis nil Chois)
Enzymic formation of 14C-kaurene from 2-14C-mevalonate was carried out with a cell-free system of Cucurbita pepo L. It was shown that either heating of the enzyme system or the addition of the growth retardants (2-chloroethyl)-trimethylammonium chloride and 2′-isopropyl-4′ (trimethylammonium chloride)-5′-methylphenyl piperidine-1-carboxylate prevented
