1. Crescimento e partição de massa seca em plantas jovens de amburana (Amburana cearensis (Fr. All.) AC Smith) e de umbuzeiro (Spondias tuberosa Arr. Cam.)
Resumo As espécies amburana (Amburana cearensis (Fr. All.) A. C. Smith) e o umbuzeiro (Spondias tuberosa Arr. Cam.) possuem adaptações fisiológicas e morfológicas às condições climáticas do bioma caatinga e atualmente estão sob ameaça de extinção. Objetivou-se com a realização deste trabalho caracterizar a partição de fotoassimilados das mud

2. Growth of tomato seedlings in substrates containing a nanocomposite hydrogel with calcium montmorillonite (NC-MMt)
RESUMO O uso correto de hidrogéis em determinadas situações pode aumentar as taxas de sobrevivência das plântulas, seu crescimento e a capacidade de retenção de água do meio de cultivo. Uma técnica para a produção de um hidrogel nanocompósito usando montmorilonita de cálcio (NC-MMt) foi desenvolvida recentemente. No entanto, resultados da pesqui

3. Growth rates and yields of cassava at different planting dates in a tropical savanna climate
ABSTRACT: Details on growth and yield for cassava planted on different dates are useful for determining suitable genotypes for particular growing seasons. Our aim was to study growth and yield of cassava planted on different dates. Four cassava genotypes (Kasetsart 50, Rayong 9, Rayong 11 and CMR38-125-77) were evaluated using a randomized complete block des

4. Biometric Responses of Soybean to Different Potassium Fertilization Management Practices in Years with High and Low Precipitation
ABSTRACT Brazilian soybean producers commonly apply maintenance potassium (K) fertilization during cultivation to restore the K taken up by plants; however, this measure can modify the morphophysiological plant characteristics, since the functions of K are closely related with plant growth and development. This study assessed the morphological changes in soy

5. Plant senescence and proteolysis: two processes with one destiny
Abstract Senescence-associated proteolysis in plants is a complex and controlled process, essential for mobilization of nutrients from old or stressed tissues, mainly leaves, to growing or sink organs. Protein breakdown in senescing leaves involves many plastidial and nuclear proteases, regulators, different subcellular locations and dynamic protein traffic

6. Physiological and agronomical responses of Syrah grapevine under protected cultivation
The performance of Syrah grapevine under protected cultivation with different plastic films was evaluated during 2012 and 2013 seasons in South of Minas Gerais State. Agronomical and physiological measurements were done on eight years old grapevines, grafted onto ‘1103 Paulsen’ rootstock cultivated under uncovered conditions, covered with transparent and

7. Improvement in yield and fruit size and quality of the main Italian table olive cultivar 'Nocellara del Belice'
Olive (Olea europaea L.) shows alternate bearing, with unreliable cropping patterns and inconsistent fruit size and quality every year. In many countries, thinning with naphthaleneacetic acid (NAA) is used to minimise alternate bearing behavior in olives. However, in Italy, growers are reluctant to employ this practice and no detailed knowledge is available

8. EstÃmulo mecÃnico na morfometria em mudas de Enterolobium contortisiliquum (Vell.) Morong / Mechanical stimulus as indicator of quality seedlings Enterolobium contortisiliquum (Vell.) Morong
This study aimed to quantify the effects induced by mechanical stimuli on the quality of seedlings Enterolobium contortisiliquum (Vell.) Morong. Treatments include five intensities of mechanical stimulation (0, 5, 10, 20 and 40 pushups) made daily for thirty days. The mechanical stimuli were initiated on December 20, 2011. Made by one-way passage of a struct

9. Growth index in massai grass under different levels of nitrogen fertilization
This study aimed to evaluate the growth index of massai grass during two regrowth cycles in a greenhouse under five levels of nitrogen (0, 150, 300, 450 and 600 mg N/dm³ of soil) and eight growth ages (5, 8, 11, 14, 17, 20, 23 and 26 days) in a split-plot design with five replications. The following variables were evaluated: net assimilation rate, herbage g

11. The promoter of a gene encoding an isoflavon reductase-like protein in coffee (Coffea arabica) drives a stress-responsive expression in leaves.
A cDNA clone (designated CaIRL) encoding an isoflavone reductase-like protein from coffee (Coffea arabica) was retrieved during a search for genes showing organ/tissue-specific expression among the expressed sequence tags (EST) of the Brazilian coffee EST database. The CaIRL cDNA contains a single open reading frame of 946 nucleotides (nt) encoding 314 amino
