Habranthus neumannii (Amaryllidaceae), a new species from Argentina
Provedor de dados: 66
Autores: Roitman,Germán; Castillo,José A; Maza,Isabel.
Habranthus neumannii, a new species found in grasslands of northwestern Argentina, is described and illustrated. The new species resembles in size Habranthus salinarum, but it can be easily distinguished by its dark green leaves, pinkish-white narrow tepals with a yellowish-brown base, by the perigonium narrowly funnelform, and the shorter style. A key to identify the species of Habranthus from Jujuy province is provided.

Relaciones filogenéticas de Rhodolirium montanum Phil. y especies afines, basadas en secuencias nucleotídicas de la región ITS y análisis cariotípico
Provedor de dados: 73

La taxonomía de los géneros chilenos de Amaryllidaceae es confusa, persistiendo problemas taxonómicos tanto a nivel de géneros como de especies. Actualmente existe controversia acerca de la correcta clasificación de especies hasta ahora asignadas a Rhodophiala C.Presl. A través del estudio de aspectos morfológicos, recientemente se ha sugerido la rehabilitación del género Rhodolirium Phil., donde Rhodolirium montanum Phil. es considerada como especie tipo. Esta especie ha sido denominada Rhodophiala rhodolirion (Baker) Traub en las clasificaciones tradicionales. Dado que los datos morfológicos han provisto información limitada y ambigua en la clasificación de las Amarilidáceas chilenas, este trabajo evalúa la pertinencia de formalizar la rehabilitación del...

Caracterização preliminar de acessos do gênero Habranthus (Amaryllidaceae).
Provedor de dados: 14
Autores: PEREIRA, R. de C. A.; CASTRO, A. C. R. de; SILVA, E. B. DA.
Está cada vez mais comum a valorização das plantas ornamentais nos centros urbanos, pois estas conferem sensação de bem-estar aos ambientes. As plantas ornamentais têm a função de transmitir harmonia, sensação de tranquilidade e conforto ao observador, contribuindo para o bem estar mental e físico (Silva et al., 2014). Contudo, apesar de embelezar o espaço, se escolhidas ao acaso, sem estudo prévio do possível impacto ambiental a ser gerado na área e da análise de suas características, não se levando em consideração seu local de origem, seu método de propagação e sua velocidade de eprodução, estas podem se tornar plantas daninhas (Gonçalves; Melo, 2013). Apesar da megadiversidade e participação em diversos programas de melhoramento genético no exterior, o...

Intrapopulational chromosome number variation in Zephyranthes sylvatica Baker (Amaryllidaceae: Hippeastreae) from Northeast Brazil
Provedor de dados: 88
Autores: Felix,Winston J. P.; Dutilh,Julie H. A.; Melo,Natoniel F. de; Fernandes,Andrea A.; Felix,Leonardo P.
Zephyranthes Herb. is a taxonomically complex and cytologically variable group, with about 65 species of Neotropical distribution. Chromosome number variability in 32 individuals of a Zephyranthes sylvatica population from Northeast Brazil was investigated. Three cytotypes were found: 2n = 12 (one metacentric, four submetacentric and one acrocentric pairs), in 24 individuals; 2n = 12 + 1B, in five and three individuals with 2n = 18, a triploid cytotype. All diploid individuals showed chromosomes with polymorphism in pair one and two, while in triploids this polymorphism was observed in all chromosome triplets, generally with two homomorphic chromosomes and a higher or lower heteromorphic chromosome. All individuals had reticulated interfasic nucleus and a...

Effects of light on the propagation and growth of bulbs of Hippeastrum hybridum cv. Apple Blossom (Amaryllidaceae)
Provedor de dados: 63
Autores: Stancato,G.C.; Mazzafera,P.
Commercially bulbs of Hippeastrum hybridum are propagated by twin scales, which are cultured in wet vermiculite in the darkness until bulbil appearance. We showed that twin scales kept under sun light produced bulbils, that once transferred to the field, did not undergo severe light stress. They had higher bulb dry weight and due to the presence of green leaves they grew faster when transplanted to the field than bulbils produced from scales kept in the darkness. An intermediary treatment (a period of darkness followed by transference to light) confirmed the advantages of producing bulbils under sun light conditions. It appears that in the field, growth of bulbs from dark grown bulbils was retarded due to the strong competition among leaves and roots for...

Hippeastrum species in areas of restinga in the state of Rio de Janeiro, Brazil: pollen characters
Provedor de dados: 39
Autores: Candido,Renata Suzano; Fourny,Ana Carolina da Silva; Gonçalves-Esteves,Vania; Lopes,Rosana Conrado.
The order Asparagales comprises 14 families, five of which occur in Brazil. Amaryllidaceae is a family of economic relevance and includes numerous ornamental genera. The genus Hippeastrum is widely distributed in Brazil and comprises 34 species, 11 of which occur in areas of restinga (coastal woodland) and Atlantic Forest in the state of Rio de Janeiro. The morphology of Hippeastrum has not been extensively studied in Brazil, where only a few systematic floristic surveys have been carried out with native species. In field studies and reviews of herbarium collections, we identified five Hippeastrum species occurring in areas of restinga in the state of Rio de Janeiro. The five species identified could be distinguished according to the following...

Ultrastructural studies on the sporogenous tissue and anther wall of Leucojum aestivum (amaryllidaceae) in different developmental stages
Provedor de dados: 42
Autores: Ekici,Nuran; Dane,Feruzan.
In this study, ultrastructures of anther wall and sporogenous tissue of Leucojum aestivum were investigated during different developmental stages. Cytomictic channels were seen between pollen mother cells during prophase I. Polar distribution was described in the organelle content of pollen mother cells and microspores in early phases of microsporogenesis and also in pollen mitosis. Active secretion was observed in tapetal cells. Previous reports about developmental stages of male gametophyte were compared with the results of this study.

A new species of Habranthus (Amaryllidaceae) from Argentina
Provedor de dados: 51
Autores: Roitman,G.; Castillo,A.; Barrios,M. R.
A new species of Habranthus is described and illustrated. H. correntinus is found in wet grasslands of northeastern Argentina. The new species resembles Habranthus tubispathus in size, but can be easily distinguished by the presence of bulblets, narrow dark green leaves, narrow pinkish tepals with darker bases, the longer style with larger style arms, and the presence of leaves at anthesis. A key to identify the species of the genus from Corrientes is provided.

Provedor de dados: 60
Autores: Emir,Ahmet; Emir,Ceren; Bozkurt,Buket; Onur,Mustafa Ali; Somer,Nehir Unver; Kaya,Gulen Irem.
ABSTRACT In the present study, a reversed-phase high-performance liquid chromatographic method has been used for the quantitative determination of lycorine in the aerial parts and bulbs of G. elwesii Hook. A simple method for the extraction of lycorine in low mass plant samples was employed utilizing pre-packed columns with diatomaceous earth (Extrelut(r)). The chromatographic separation was performed using an isocratic system with a mobile phase of trifluoroacetic acid-water-acetonitrile (0.01:92.5:7.5, v/v/v) applied at a flow rate 1 mL min-1 using diode array detector. The content of lycorine in the bulbs and aerial parts of G. elwesii collected from Demirci (Manisa) was found as 0.130 and 0.162 %, respectively. Additionally, in the bulbs of the...

Genetic variation within three populations of Phycella australis (Phil.) Ravenna from Biobío Region, Chile, evaluated using ISSR markers
Provedor de dados: 117
Autores: Flores,Cristian; Delaveau,Catherine; Alvarez,Carolina; Vergara,Dafne; Baeza,Carlos; Ruiz,Eduardo; Uribe,Matilde.
Phycella australis (Phil.) Ravenna is a Chilean plant with high ornamental potential; however, the intensive extraction as a cut flower might be detrimental for the conservational state by ignoring the state of genetic variation. The objective of this investigation was to assess genetic variability within and between three populations of P. australis in the Biobío Region using inter-simple sequence repeat (ISSR) markers. The evaluated areas correspond to three locations in the province of Concepción, Biobío Region: Desembocadura (36°48' S, 73°10' W), Santa Juana (36°58' S, 72°58' W), and Lipinhue (37°00' S, 72°58' W). Six ISSR primers were used obtaining 51 fragments, from which 72.5% were polymorphic. From the three evaluated sites Santa Juana showed a...
