In vitro conservation of apical meristem-tip of Melia azedarach L. (Meliaceae) under slow-growth conditions: (with 1 table &amp;#38; 2 figures)
Provedor de dados: 85
Autores: Scocchi,AM; Mroginski,LA.
Studies on in vitro storage of Melia azedarach -"paradise tree"- under slow-growth conditions were carried out to develop an efficient protocol for the conservation of the genetic diversity of the crop. The response to different growth retardation treatments was examined using clone E. In vitro cultures of apical meristem-tips (0.2-0.3 mm in length) could be effectively maintained for 12 months at 4ºC on ¼ MS basal medium supplemented with 0.5 µM BA. Shoot proliferation was observed on 67 % of the recovered apical meristem-tips, after 12 months at 4ºC. Rooting of the regenerated shoots was achieved by reculturing them on MS + 17.5 µM IBA, during 4 days and subsequently transferred to MS medium lacking growth-regulators for 30 days. Complete plants were...

Ethylene and abscisic acid in the control of development of the rhizome of Kohleria eriantha (Benth.) Hanst. (Gesneriaceae)
Provedor de dados: 61
Autores: Almeida,Julieta Andrea Silva de; Kascheres,Concetta; Pereira,Maria de Fátima D.A.
Kohleria eriantha has rhizomes which are underground stems with buds enclosed by modified leaves, that store starch. The buds of this rhizome can develop in two morphological patterns: an aerial shoot (similar to the mother plant) or a rhizome, depending on the water level present in the substrate. Development of the shoot was inhibited by low water availability (1 mL) in the substrate. It was verified that ethylene and ABA were involved in controlling the development of the rhizome pattern under low water availability. Treatments with ethrel, PEG and ABA induced shoot development whereas treatments with AgNO3 or AVG inhibited shoot development. Increased ethylene and ABA were observed under conditions that inhibited shoot development. Moreover, it is...
