Well-formed and healthy propagative material is essential for economic success in fruit growing. The health of the seedlings must be ensured during production to prevent the death of plants and spread of pathogens to new areas, which cause an increase in production costs and reduction in yield, with some pathogens making production unviable in the areas where they are introduced. The most viable strategy for disease control in propagative material is the use of resistant cultivars. However, for many fruit cultivars sources of resistance have not yet been identified and in some cases the resistance is ?broken? by the emergence of new races of the pathogen. Other measures are also important and recommended in plant propagation, such as the use of integrated disease management, the use of cultural and biological methods, substrate preparation, irrigation management, grafting, balanced nutrition and use of organic matter, eliminating the initial inoculum, and reducing the disease rate. Among the various procedures in nurseries for ensuring the health of seedlings are the use of pathogen-free seeds and cuttings, handling of substrates in clean facilities, disinfection of hands, tools and containers, maintenance of water quality for irrigation, and the elimination of invasive plants. It is important to clean the nurseries and have a suitable place for the disposal of seedlings, substrates and crop residues. A record and history of the operations in the production of seedlings should be a routine, as well as security and control in access to greenhouses or nurseries. The application of knowledge and the best strategies of integrated disease management for the production of healthy seedlings, guarantees the quality of the productive material and the success of the crop.
Mudas bem formadas e sadias são o sucesso econômico na fruticultura. A sanidade das mudas deve ser assegurada durante o processo de produção, evitando a morte de plantas e a disseminação de patógenos para novas áreas, tendo como consequência o aumento do custo de produção e a redução da produtividade, podendo determinados patógenos, inviabilizar temporária a cultura nas áreas onde foram introduzidos. As doenças no material propagativo estão entre as principais causas de redução na produtividade agrícola e a estratégia mais viável para o seu controle é o uso de cultivares resistentes. Entretanto, para muitas fruteiras ainda não foram identificadas as fontes de resistência e, em alguns casos a resistência é ?quebrada? pelo surgimento de novas raças do patógeno. Outras medidas também são importantes e recomendadas na propagação, como a utilização do manejo integrado, com o uso de métodos culturais e biológicos, preparo do solo, manejo da irrigação, enxertia, nutrição equilibrada e uso da matéria orgânica, eliminando o inóculo inicial e/ou pela redução da taxa da doença. Entre os vários procedimentos nos viveiros visando à sanidade das mudas, estão também a utilização de sementes e estacas isentas de patógenos, a manipulação dos substratos em locais limpos, a assepsia das mãos, ferramentas e recipientes, a utilização de água para irrigação com qualidade e a eliminação de plantas invasoras. É importante a limpeza dos viveiros e ter um local adequado para o descarte de mudas, de substratos ou de restos de cultura. Deve-se manter uma rotina do registro e histórico das operações na produção de mudas, bem como a segurança e o controle no acesso às estufas ou viveiros.

Four clones of robusta coffee representing drought-tolerant (14 and 120) and drought-sensitive (46 and 109A) genotypes were submitted to a slowly imposed water deficit. Sampling and measurements were performed when predawn leaf water potential (Ψpd) approximately −2.0 and −3.0 MPa was reached. Regardless of the clone evaluated, drought led to sharper decreases in stomatal conductance than in photosynthesis, which was accompanied by significant declines in internal to ambient CO2 concentration ratio. Little or no effect of drought on chlorophyll a fluorescence parameters was observed. Regardless of the stress intensity, starch decreased remarkably. This was not accompanied by significant changes in concentration of soluble sugars, with the exception of clone 120 in which a rise in sucrose and hexose concentrations was found when Ψpd reached −3.0 MPa. At Ψpd = −2.0 MPa, activity of acid invertase increased only in clone 120; at Ψpd = −3.0 MPa, it increased in clones 14, 46 and 120, while activity of sucrose synthase declined, but only in clone 109A. Drought-induced decrease in ADP-glucose pyrophosphorylase activity was found only in clones 14 and 46, irrespective of stress intensity. At Ψpd = −3.0 MPa, maximal extractable and activation state of sucrose-phosphate synthase (SPS) decreased in all clones with the exception of clone 120, in which SPS activity was maintained in parallel to a rising activity of fructose-1,6-bisphosphatase. Changes in SPS activity could neither be explained by the CO2 decrease linked to stomatal closure nor by differences in leaf water status.
