13. Controle da hidratação para o condicionamento osmótico de sementes de aspargo
Como o aspargo apresenta a germinação da semente e a emergência da plântula lentas, justifica-se o uso de técnicas que acelerem a germinação, como o condicionamento osmótico das sementes. Inicialmente, para definir as melhores condições de condicionamento das sementes, é necessário conhecer os padrões de embebição dessas sementes para se ter u

14. Selección de progenitores en espárrago
O objetivo principal deste trabalho foi determinar as variáveis que melhor explicam a variação entre indivíduos dentro da população de aspargos originária da cultivar Argenteüil e selecionar plantas superiores para compor novas populações. O ensaio, composto por 1280 plantas, foi instalado no campo experimental da Facultad de Ciencias Agrarias de l

15. Distribuição radicular de cultivares de aspargo em áreas irrigadas de Petrolina - PE
A distribuição radicular de duas cultivares de aspargo (New Jersey 220 e UC 157 F1), irrigadas por aspersão convencional, foi avaliada durante o ano de 1997 em solos de textura arenosa, em plantio experimental e comercial, respectivamente, nos Projetos de Irrigação de Bebedouro e Senador Nilo Coelho, em Petrolina (PE). O objetivo foi obter informações

16. Evaluación de siete poblaciones de espárrago (Asparagus officinalis L.)
The materials of asparagus (Asparagus officinalis L.) that growers have in use are imported by seed dealers and have been selected according to overseas markets requirements. With the aim of selecting proper parents to use in a breeding program, seven populations of Asparagus officinalis (P1 to P7), all rised as white asparagus, were tested during 1993 and 1

17. Amino Acid Uptake into Cultivated Mesophyll Cells from Asparagus officinalis L 1
The uptake of threonine, aspartic acid, and isoleucine into cultivated asparagus cells was examined under culture conditions.

18. An Agrobacterium-transformed cell culture from the monocot Asparagus officinalis
Cultured stem fragments from the monocotyledonous plant Asparagus officinalis infected by the oncogenic bacterium Agrobacterium tumefaciens developed tumorous proliferations. This tissue was propagated in vitro on hormone-free culture medium. The T-DNA-encoded markers nopaline and agrocinopine were unambiguously detected in these tissues. The data demonstrat

20. T-DNA organization in tumor cultures and transgenic plants of the monocotyledon Asparagus officinalis
Asparagus officinalis was the first monocotyledonous plant from which hormone-independent and opine-producing crown gall tissue could be isolated. We confirm by DNA hybridization that tumor lines obtained after infection of this plant by Agrobacterium strains harboring wild-type nopaline and octopine tumor-inducing (Ti) plasmids are stably transformed and co

21. Expression and Function of Cell Wall-Bound Cationic Peroxidase in Asparagus Somatic Embryogenesis
Cultured asparagus (Asparagus officinalis L. cv Y6) cells induced to regenerate into whole plants through somatic embryogenesis secreted a 38-kD protein into cell walls. The full-length cDNA sequence of this protein (Asparagus officinalis peroxidase 1 [AoPOX1]) determined by reverse transcriptase-polymerase chain reaction showed similarity with plant peroxid

22. Similarities in Gene Expression during the Postharvest-Induced Senescence of Spears and Natural Foliar Senescence of Asparagus.
Changes in gene expression and tissue composition were investigated during foliar development and natural senescence of asparagus (Asparagus officinalis L.). Three phases in development and senescence of the foliage were characterized: early fern growth, mature fern, and senescence, when a marked loss of chlorophyll, sucrose, and protein occurred and major c

23. Isolation and characterization of a cDNA clone for a harvest-induced asparagine synthetase from Asparagus officinalis L.
A full-length cDNA clone (pTIP27) encoding asparagine synthetase (AS; EC 6.3.5.4) was isolated from a cDNA library prepared from the tip section (apex to 30 mm) of Asparagus officinalis L. spears. The cDNA clone encodes an mRNA of 1978 bp, giving a derived protein of 66.5 kD molecular mass. The derived amino acid sequence is 81% homologous to AS from Pisum s

24. Phytosulfokine, sulfated peptides that induce the proliferation of single mesophyll cells of Asparagus officinalis L.
Proliferation of dispersed plant cells in culture is strictly dependent on cell density, and cells in a low-density culture can only grow in the presence of conditioned medium (CM). No known plant hormones have been able to substitute for CM. To quantify the mitogenic activity of CM, we examined conditions for the assay system using mechanically dispersed me
