This book was released on 1992 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ensaios de germinacao e observacao da morfologia e embriologia das sementes e plantulas de umbu (Spondias tuberosa Arr. Cam.), cajarana (Spondias cytherea Sonn.) e caja (Spondias lutea L.) foram realizados no Laboratorio de Frutas Tropicais e Laboratorio de Analises de Sementes do Centro de Ciencias Agrarias da Universidade Federal da Paraiba com o objetivo de observar a forma e constituicao da semente, estudar a germinacao e a morfologia das plantulas nos primeiros estadios de desenvolvimento. Os resultados dos ensaios e das descricoes das sementes mostraram que o umbuzeiro inicia a germinacao aos 14 dias apos o semeio, seguido de cajarana e do caja. As plantulas de umbu iniciaram a formacao de xilopodios apos 25 dias de germinadas e a principal diferenca comrelacao a morfologia e embriologia entre as especies esta na forma da semente e do eixo hipocotilo-radicula. As sementes de umbu apresentam forma reniforme e eixo hipocotilo-radicula cilindrico; as de cajarana, apresentam forma de cilindrica a claviforme e eixo hipocotilo radicula discoide; as de caja apresentam-se claviforme carpos dessas especies apresentam varios loculos. No umbu, observou-se apenas uma semente no loculo central, na cajarana ate seis sementes, sendo uma em cada loculo, e no caja ate oito loculos, com o central mais desenvolvido e contendo a semente.

This book was released on 1999 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: O umbuzeiro e uma planta de iportancia socio-economica para o Nordeste brasileiro, porem a multiplicacao de genotipos superiores tem sido limitada porque a epoca de coleta de garfos se restringe ao periodo de repouso da planta matriz. Os metodos de enxertia utilizados tem sido estudados porem nao se sabe como se comportam se utilizados garfos de diferentes fases fenologicas da planta de umbuzeiro. Assim sera desejavel se definir quais as melhores epocas do ano para se retirar garfos e metodos mais vantajosos de enxertia, na propagacao vegetativa do umbuzeiro (Spondias tuberosa Arr, Cam), bem como identificar algumas variaveis fisiologicas e fenologicas, que poderao interferir no indice de pegamento dos enxertos e entre outros atributos das mudas produzidas. Os experimentos foram conduzidos na sede da Embrapa Semi-Arido, situada a 45 km de Petrolina-PE, sob condicoes de viveiro no ano de 1998. Empregou-se o delineamento em blocos ao acaso, com tres tratamentos e oito repeticoes em cada epoca. Os tratamentos foram constituidos de dois metodos de garfagem (no topo em fenda cheia e a inglesa simples) e um de borbulhia em "T" invertido. Os experimentos foram instalados nos meses de janeiro, marco, maio, julho e setembro. Essas epocas compreenderam as diferentes fases fenologicas da planta matriz da qual se retiraram os garfos. As analises estatisticas foram realizadas para avaliar as diferencas entre os metodos em cada epoca e conjuntamente, considerando epocas, metodos e a interacao metodo x epoca como efeitos fixos. Os resultados obtidos permitiram concluir que: a) a enxertia do umbuzeiro pode ser realizada em qualquer epoca do ano, para os metodos de garfagens em fenda cheia e a inglesa simples, independente do estadio fenologico em que a planta matriz fornecedora de garfos se encontra; b)os metodos de enxertia recomendados para multiplicacao vegetativa do umbuzeiro sao as garfagens em fenda cheia e a inglesa simples; c) as variaveis fisiologicas como fotossintese, potencial hidrico da planta, contudancia e resistencia estomatica, nao correlacionaram-se com o indice de pega dos enxertos.
Book Synopsis Estudos da quebra de dormencia da semente do umbuzeiro (Spondias tuberosa, Arr. Camara). by : C. de O. CAMPOS

This book was released on 1986 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: Estudar a quebra de dormencia da semente do umbuzeiro (Spondias tuberosa, Arr. Camara) e uniformizar a sua germinacao. Numa serie inicial de observacoes, carocos de umbuzeiros foram cortados em forma de bisel em sua face distal e postos para absorverem agua em papel Germitest. Um lote de carocos foi ruminado por caprinos e o outro nao. A experiencia foi repetida nos mesmos moldes, em carocos intactos. Os resultados indicam que os carocos do umbuzeiro absorvem agua, quer tenham sido ruminados eou nao, e que o corte em forma de bisel foi eficiente na quebra da dormencia, eliminando a resistencia mecanica exercida pelo endocarpo. Um terceiro experimento consistiu na pre-embebicao de carocos ruminados e cortados, em solucoes de Acido Giberelico (AG3) com as seguintes concentracoes: 0,2; 0,4; 0,6; 0,8 e 1,0 uM. Verificou-se que o AG3 sob tais concentracoes, nao apresentou influencia significativa na percentagem de emergencia. No entanto, observou-se que as plantulas provenientes de sementes tratadas com AG3 foram mais vigorosas que aquelas oriundas de sementes pre-embebidas em agua. Em um quarto experimento observou-se a influencia do tamanho de carocos nao ruminados e cortados na velocidade de emergencia e no vigor de plantulas. Os resultados indicam que aqueles de menor diametro possibilitaram emergencia mais rapida de plantulas. Entretanto, dos carocos medios e grandes emergiram plantulas com maior vigor, o que recomendaria a utilizacao preferencial desses ultimos para a producao comercial de mudas.

Available in PDF, EPUB and Kindle. Book excerpt: This book represents an interdisciplinary approach to the relevant aspects of agricultural production related to the interactions between natural processes, human activities and the environment. It provides condensed and comprehensive knowledge on the functions of various agroecosystems at the field, landscape and global scale. Understanding and integrating complex ecological processes into field production, land management and food systems is essential in order to deal with the challenges of modern crop and livestock production: the need for food security for the growing human population, and the necessity to combat the detrimental effects of food production on the environment. The book provides the scientific basis required by students and scientists involved in the development of sustainable agroecosystems and contributes to a range of disciplines including Agriculture, Biology, Geography, Landscape Ecology, Organic Farming, Biological Control, and Global Change Ecology.

Book excerpt: This single volume explores the theoretical and the practical aspects of crop physiological processes around the world The marked decrease over the past century in the land available for crop production has brought about mounting pressure to increase crop yields, especially in developing nations. Physiology of Crop Production provides cutting-edge research and data for complete coverage of the physiology of crop production, all in one source, right at your fingertips. This valuable reference gives the extensive in-depth information soil and crop professionals need to maximize crop productivity anywhere the world. Leading soil and plant scientists and researchers clearly explain theory, practical applications, and the latest advances in the field. Crop physiology is a vital science needed to understand crop growth and development to facilitate increases of plant yield. Physiology of Crop Production presents a wide range of information and references from varying regions of the world to make the book as complete and broadly focused as possible. Discussion in each chapter is supported by experimental data to make this book a superb resource that will be used again and again. Chapter topics include plant and root architecture, growth and yield components, photosynthesis, source-sink relationship, water use efficiency, crop yield relative to water stress, and active and passive ion transport. Several figures and tables accompany the extensive referencing to provide a detailed, in-depth look at every facet of crop production. Physiology of Crop Production explores management strategies for: ideal plant architecture maximizing root systems ideal yield components maximizing photosynthesis maximizing source-sink relationship sequestration of carbon dioxide reducing the effects of drought improving N, P, K, Ca, Mg, and S nutrition improving micronutrient uptake Physiology of Crop Production is an essential desktop resource for plant physiologists, soil and crop scientists, breeders, agronomists, agronomy administrators in agro-industry, educators, and upper-level undergraduate and graduate students.
