Acclimatization of coffee seedlings obtained from zygotic embryos of aged seeds.

Coffee seeds rapidly lose viability during storage, which hinders the development of vigorous seedlings for crop establishment. There are reports that seed endosperm is more sensitive to deterioration than embryos, which can be excised and cultivated in vitro. However, a substantial number of plants...

There are reports that seed endosperm is more sensitive to deterioration than embryos, which can be excised and cultivated in vitro. However, a substantial number of plants grown in vitro do not survive during transfer to a greenhouse or field environment. The objective of this study was to evaluate the acclimatization of coffee seedlings of cultivar Catuaí Amarelo IAC 62, developed from zygotic embryos obtained from aged seeds in different substrates and environments, for the production of well-developed seedlings suitable for planting. For this purpose, seedlings were obtained from the in vitro cultivation of embryos obtained from seeds of two quality levels: freshly harvested seeds and artificially aged seeds. Zygotic embryos were extracted from the seeds and cultivated in MS medium. At 60 days, the percentages of normal and abnormal seedlings and dead seeds were evaluated. The good-quality seedlings grown in vitro for 60 days were transplanted into two different substrates (Tropstrato and coconut fiber) and acclimatized in two environments (growth room and greenhouse with a misting system). The plants were evaluated for height, stem diameter, number of leaves, chlorophyll content, and growth rate. The greenhouse environment was better for seedling growth, possibly due to its higher sunlight and temperature. The best substrate was coconut fiber, as it ensured better development of plants from freshly harvested seeds and those from aged seeds. It is possible to develop healthy seedlings from seeds with low viability.ANA LUIZA OLIVEIRA VILELA, UNIVERSIDADE FEDERAL DE LAVRA; STTELA DELLYZETE VEIGA F DA ROSA, CNPCa; STEFÂNIA VILAS BOAS COELHO, UNIVERSIDADE FEDERAL DE LAVRA; CRISTIANE CARVALHO PEREIRA, UNIVERSIDADE FEDERAL DE LAVRA; ANA CRISTINA DE SOUZA, UNIVERSIDADE FEDERAL DE LAVRA; FERNANDO AUGUSTO SALES RIBEIRO, UNIVERSIDADE FEDERAL DE LAVRA.2022-11-25T15:01:20Z2022-11-25T15:01:20Z2022-11-252022info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleAustralian Journal of Crop Science, v. 16, n. 9, p. 1127-1134, 2022.1835-2707http://www.alice.cnptia.embrapa.br/alice/handle/doc/1148763https://doi.org/10.21475/ajcs.22.16.09.p3628enginfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da EMBRAPA (Repository Open Access to Scientific Information from EMBRAPA - Alice)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAVILELA, A.
