Crescimento, fotossíntese e composição mineral em genótipos de Coffea com potencial para utilização como porta-enxerto

Abstract: Foi estudado o desenvolvimento da parte aérea e das raízes, as trocas gasosas fotossintéticas e a composição mineral nos genótipos de Coffea, Apoatã IAC 2258 (C. canephora); Bangelan IAC col. 5 (C. congensis X C. canephora); Catuaí IAC 144 (C. arabica); Excelsa (C. liberica, var. dewevrei) e Piatã (IAC 387) (C. arabica X C. liberica, var. dewevrei), visando conhecer seus potenciais para utilização como porta-enxerto em C. arabica. Utilizaram-se plantas jovens cultivadas em terra, contida em saco plástico e em … Show more

“…Root growth: The main part of the root system of an arabica coffee tree is generally concentrated in the first 0.30 m layer from the soil surface and distributed in a circle of about 1.50 m in diameter around the trunk (Sáiz del Rio et al, 1961;Inforzato and Reis, 1973;Huxley et al, 1974;Alfonsi et al, 2005). This architectural pattern also seems to be similar for conilon coffee (Rena and DaMatta, 2002).…”

“…This architectural pattern also seems to be similar for conilon coffee (Rena and DaMatta, 2002). In any case, the root system of both coffee species is highly plastic and its distribution and length are also age-dependent (Inforzato and Reis, 1973;Brangança, 2005), in addition to varying with planting density (Cassidy and Kumar, 1984;Rena et al, 1998), genotypes (Alfonsi et al, 2005;Pinheiro et al, 2005;Cavatte et al, 2008), soil characteristics (Rena and DaMatta, 2002), cultural practices (Sáiz del Rio et al, 1961;Cassidy and Kumar, 1984;Rena and DaMatta, 2002;Barreto et al, 2006), and weed competition .…”

“…Entre as diversas culturas perenes, o café destaca-se pela alta sensibilidade à competição exercida pelas plantas daninhas, com reflexos negativos no crescimento das plantas jovens. Essa alta sensibilidade da cultura do café à interferência das plantas daninhas pode ser atribuída à competição por nutrientes (Ronchi et al, 2003), luz e água (Alfonsi et al, 2005).…”

“…No caso do comportamento do sistema radicular, em função dos diferentes materiais genéticos, os principais trabalhos foram feitos com C. canephora (Alfonsi et al, 2005;Bragança, 2005;Pinheiro et al, 2005;Silva et al, 2010;Covre et al, 2013); porém, não há informações para C. arabica, que atualmente tem muitas cultivares novas (Carvalho, 2008;Bliska et al, 2011).…”
