Resumo: The objective of this work was to evaluate quantitatively the morphological, anatomical and bromatological characteristics of leaves of ten mulberry cultivars, and to establish the preferences shown by the silkworm. The upper (5th) and median (15th) leaves were collected taking branch top into account. In order to compare cultivars, multivariate statistic methods of cluster analysis and principal component analysis were used. The cultivars Korin, Calabresa, IZ 5/2 and IZ 15/7 were considered as the most appropriate to feed silkworms, since they presented high percentage values of eaten leaves, due to certain characteristics such as lower crude fiber contents, lower quantity of cystolith and mucilage idioblasts, lower proportions of epidermis and higher quantities of parenchyma, in relation to the other studied cultivars. Cultivars IZ 13/6 and IZ 57/2 were considered as less recommendable. The other cultivars formed an intermediate group, in relation to silkworm preferences.

Foram coletadas as folhas superior (5a) e mediana (15a) da planta, contadas a partir do ápice. As cultivares foram comparadas pelos métodos estatísticos multivariados de análise de agrupamento e análise de componentes principais. As cultivares Korin, Calabresa, IZ 5/2 e IZ 15/7 foram consideradas as mais recomendáveis para a alimentação das lagartas do bicho-da-seda, pois apresentaram valores altos de porcentagem de folha consumida, atribuídos à ocorrência de características desejáveis nas folhas, tais como menor teor de fibra bruta, menor quantidade de idioblastos de cistólito e de mucilagem, menor proporção de epiderme e maior de parênquima, comparativamente, às outras cultivares estudadas. As cultivares IZ 13/6 e IZ 57/2 foram consideradas as menos recomendáveis. As demais cultivares comportaram-se como intermediárias na preferência do bicho-da-seda.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraOkamoto, FumikoRodella, Roberto Antonio2006-02-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7120Pesquisa Agropecuaria Brasileira; v.41, n.2, fev. 2006; 195-203Pesquisa Agropecuária Brasileira; v.41, n.2, fev. 2006; 195-2031678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7120/4165info:eu-repo/semantics/openAccess2010-12-28T16:15:48Zoai:ojs.seer.sct.embrapa.br:article/7120Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-12-28T16:15:48Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
