1. RELAÇÃO ENTRE O TEOR ABSOLUTO E RELATIVO DE CLOROFILA EM FOLHAS DE VIMEIRO
Os métodos tradicionais para a quantificação de clorofilas implicam na destruição das folhas, além de serem demorados e dispendiosos. Uma alternativa aos métodos destrutivos é o uso de medidores portáteis, dentre eles o SPAD 502, que mede a intensidade da cor verde das folhas, resultando no índice SPAD (Soil Plant Analysis Development). No entanto,

3. POTENCIAL BIOTÉCNICO DO SARANDI-BRANCO (Phyllanthus sellowianus Müll. Arg.) E VIME (Salix viminalis L.) PARA REVEGETAÇÃO DE MARGENS DE CURSOS DE ÁGUA
RESUMO Mesmo com planejamento e trabalho cuidadoso no uso dos recursos naturais, em particular dos cursos de água, é inevitável que algumas áreas sejam modificadas negativamente, que partes de margens ou encostas percam sua estabilidade e que ocorram erosões e deslizamentos. Quando isso acontece é necessária a recomposição e a estabilização físic

4. Abscisic Acid and the Photoperiodic Induction of Dormancy in Salix viminalis L 1
A series of growth room experiments was carried out aiming to establish the role of abscisic acid on dormancy of Salix viminalis L. The inhibitor content and abscisic acid levels of extracts from roots, sap, leaves, and apical tissues of willow were measured using biological assay and gas-liquid chromatography.

5. Endogenous Gibberellins in Elongating Shoots of Clones of Salix dasyclados and Salix viminalis1
Elongating shoots of rapidly growing clones of Salix viminalis L. (clone 683-4) and Salix dasyclados Wimm. (clone 908) harvested in early August were analyzed for endogenous gibberellins (GA). Distribution of GA-like activity, determined by Tan-ginbozu dwarf rice microdrop bioassay after reverse phase C18 high performance chromatography, was similar for both

6. Seasonal Variation in the Hormone Content of Willow: I. Changes in Abscisic Acid Content and Cytokinin Activity in the Xylem Sap 1
Changes in levels of abscisic acid (ABA) and cytokinin activity in the xylem sap of willow (Salix viminalis, L.) were followed throughout two growth cycles.

7. Plant Viability as a Function of Temperature Stress (The Richards Function Applied to Data from Freezing Tests of Growing Shoots).
Frost resistance of growing Salix viminalis L. shoots was determined by rating mortality percentage under two commonly used freezing conditions: a condition in which plants were encased in crushed ice and another in which plants were moistened with tap water prior to freezing. The mortality-temperature data were fitted with a logistic function (having a fixe
