1. Comparative vegetative anatomy of Neotropical Goodyerinae Klotzsch (Orchidaceae Juss.: Orchidoideae Lindl.)
ABSTRACT The Neotropical genera Aspidogyne and Microchilus (Goodyerinae, Cranichideae, Orchidaceae) comprise ca. 200 rainforests terrestrial species. Although species of Goodyerinae are described with similar anatomy to other taxa of Cranichideae, some anatomical characteristics appear to be specific to the subtribe. Our goal was to characterise the anatomic

2. Weed Interference on the Accumulation of Dry Mass and Macronutrients of Eggplant ‘Nápoli’
RESUMO: A convivência com plantas daninhas pode afetar o crescimento e a nutrição de culturas agrícolas devido à interferência. O objetivo deste estudo foi avaliar a interferência das plantas daninhas na distribuição de massa seca e no acúmulo de massa seca e de macronutrientes em plantas de berinjela. Os tratamentos consistiram de períodos cresce

3. Somatic embryos from Phalaenopsis classic Spotted Pink (Orchidaceae) protocorms
RESUMO: O presente estudo buscou induzir a formação de embriões somáticos em protocormos do híbrido Phalaenopsis Classic Spotted Pink em dois estádios de maturação fisiológica aos 80 e 120 dias após a inoculação das sementes (DAIS). Os protocormos foram inoculados em meio ½ MS suplementado com 0,1 mg L-1 de ANA e 3 mg L-1 de TDZ. Aos 15 dias de

4. Lysine metabolism and amino acid profile in maize grains from plants subjected to cadmium exposure
ABSTRACT: In general, the effects of Cadmium (Cd) on crop quality are evaluated solely by Cd accumulation in the edible plant parts; thus, the potential effects on several nutritional features are not often taken into account. This study evaluated Cd effects on the enzymatic activities of lysine (Lys) metabolism, storage protein and amino acid profile in mai

5. Fructan dynamics in the underground organs of Chresta exsucca (Asteraceae), a dry season flowering species
ABSTRACT Climatic seasonality has an influence on the phenology of native Cerrado plants. Herbs and subshrubs tend to flower in the rainy season, although some species of these habits flower in the dry season. Reserve carbohydrates, stored in the underground organs, are used to support phases of high energy-demand, but also may protect plants from damage dur

6. Pharmacobotanical study of Hypericum thymopsis
ABSTRACT Hypericum thymopsis Boiss., Hypericaceae, is an endemic herb which generally grows at the calcareous steppe regions of Central Turkey. In flowering stage, the aerial parts of this species are used for wound-healing and sedation, and its infusions are used against stomach diseases and throat infections by local people. The aim of this study, to exami

7. Trichomes that secrete substances of a mixed nature in the vegetative and reproductive organs of some species of Moraceae
ABSTRACT This study aimed to obtain new information about the distribution, morphology and content of secretory trichomes present in the vegetative and reproductive organs of four species of Moraceae: Artocarpus heterophyllus, Dorstenia cayapia, Maclura tinctoria and Sorocea bonplandii. Stem, leaf, flower and inflorescence samples were processed for scanning

8. The structural studies on the medicinal plant Haplophyllum telephioides
ABSTRACT Haplophyllum telephioides Boiss., Rutaceae, is an endemic herb which generally grows at the steppe region in Central Turkey. Its aerial parts in flowering stage are used by local people against influenza virus due to its antimicrobial effect. The main purpose of this study was to examine the morphology, anatomy and histology of the vegetative and re

9. Anatomy and fructan distribution in vegetative organs of Dimerostemma vestitum (Asteraceae) from the campos rupestres
Entre os compostos armazenados pelas plantas, várias funções são atribuídas aos frutanos, tais como fonte de energia e proteção contra seca e temperaturas extremas. No presente estudo nós analisamos a anatomia e a distribuição de frutanos nos órgãos vegetativos de Dimerostemma vestitum (Asteraceae), uma espécie endêmica dos campos rupestres bra

10. Doses of caffeine on the development and performance of pepper crops under greenhouse
A number of experiments on plant organs demonstrated that caffeine acts as a growth stimulator. In this study we aimed to determine the influence of caffeine on development of pepper crops under stress in the autumn-winter cycle, as peppers stop growing and developing in November and January. The experiments were conducted to determine how caffeine applied t

11. Aerial stem and leaf morphoanatomy of some species of Smilax
This study aimed to describe the morphoanatomy of the aerial vegetative organs of seven Smilax species, used in Brazilian folk medicine. Samples of leaves and stems were fixed with FAA 50, embedded in historesin, sectioned on a rotary microtome, stained and mounted in synthetic resin. Cuticle ornamentation was analyzed with standard scanning electron microsc
