1. Variation in root morphology of epiphytic orchids along small-scale and large-scale moisture gradients
ABSTRACT Root morphology is expected to respond to environmental conditions. Two earlier studies reported predictable changes in the structure of the velamen radicum (common in monocotyledons) along rainfall gradients, which was expected from its assumed role in plant-water-relations. The present study expanded on this idea by analysing nine root traits that

3. Water relations in parsley plants cultivated in brackish nutrient solutions of different cationic natures
RESUMO A análise da resposta das plantas à variabilidade catiônica das águas, somado ao componente osmótico, é imprescindível no contexto do estresse salino. Neste sentido, entre outubro de 2017 e fevereiro de 2018, em Recife, PE (8° 1’ 7” S e 34° 56” 53” O, e altitude de 6,5 m), o presente trabalho foi desenvolvido com o objetivo de avaliar

4. Water relations of chives in function of salinity and circulation frequency of nutrient solutions
RESUMO O cultivo hidropônico com o uso de águas salobras, constitui-se em uma alternativa para a produção agrícola, especialmente no cultivo de hortaliças. Sendo assim, desenvolveu-se o presente trabalho com o objetivo de avaliar o consumo, eficiência e o teor de água, bem como a partição de massa seca de plantas de cebolinha (Allium schoenoprasum)

5. Pulse drip irrigation and fertigation water depths in the water relations of coriander
RESUMO O presente trabalho foi desenvolvido com o objetivo de avaliar o efeito do gotejamento por pulsos, sob diferentes níveis da lâmina de fertirrigação, nas principais relações hídricas da cultura do coentro (Coriandrum sativum). O experimento foi realizado em condições de ambiente protegido, nas dependências da UFRPE, campus Dois Irmãos, Recif

6. WATER RELATIONS AT THE INITIAL SUGARCANE GROWTH PHASE UNDER VARIABLE WATER DEFICIT
ABSTRACT This study aimed to quantify water deficit levels that compromise sugarcane initial growth exposed to different availability soil depths. The experiment was conducted in a greenhouse by using 100-liter capacity asbestos-cement boxes filled with different soil layers simulating depths of 10, 20, 30, and 40 cm. Water deficit levels were represented by

7. Ploidy levels in Citrus clementine affects leaf morphology, stomatal density and water content
The objective of the present study was to understand the relationship among leaf morphology, stomatal characteristics and water relations in triploids generated through anther culture and their counterpart diploid plant of C. clementina. Triploid plants possessed small and narrow leaves as compared to diploid plant as evident by less leaf length, leaf width

8. A non-invasive plant-based probe for continuous monitoring of water stress in real time: a new tool for irrigation scheduling and deeper insight into drought and salinity stress physiology
The non-invasive, magnetic leaf patch clamp pressure probe (also termed ZIM-probe) allows for the first time to measure continuously turgor pressure changes of plant leaves over long periods of time with high precision and in real time. The probe has become an important tool in plant physiology, molecular biology and ecology, but also in agriculture because

9. SE PLANTA E COLHE ALIMENTOS NESTE SERTÃO: resistência e permanência da autonomia camponesa e as estratégias do MPA (Movimento dos Pequenos Agricultores) nas contradições do projeto da soberania alimentar. / IF THIS PLANT FOOD AND REAP SERTÃO: resistance and persistence of peasant autonomy and strategies of the MPA (Movement of Small Farmers) contradictions in the design of food sovereignty.
This dissertation has the objective of analyze the production unit of the rural family, from the Small Agriculture Movement MPA. To reach this objective, a historic study of the MPA was carried out, its organization, specialization, its relation with the rural way. We focused our research in the territory of the High back-country of Sergipe, which configures

10. Physiological and biochemical responses to drought stress in Barbados cherry
To evaluate physiological genotypic differences between two Barbados cherry genotypes (13- and 14-CPA) under water deficit, initial growth, water relations, and organic solute accumulation were evaluated in an experiment performed using four-month-old seedlings, which were subjected to four water treatments (100, 75, 50, and 25% of field capacity), with five

12. Fisiologia e produtividade do algodoeiro em solo encharcado na fase de plantula.
O algodoeiro herbáceo (Gossypium hirsutum L. r. latifolium Hutch.) é uma planta considerada sensível à deficiência de oxigênio do solo. O objetivo deste trabalho foi avaliar a fisiologia e produtividade do algodoeiro cultivar CNPA 7H, em casa de vegetação, submetido à anoxia, por encharcamento do solo, na fase de plântula. Foram conduzidos dois exp
