1. Parthenocarpy induction and reduction of seeds in fruits of 'Nadorcott' mandarin
ABSTRACT Mandarins commercialization at international market requires seedless fruit production in addition to its ideal organoleptic and visual quality. The objective of the work was to evaluate the efficiency of applications of gibberellic acid and of copper sulfate during anthesis in reducing the number of seeds and in the productive behavior of the 'Nado

2. Silicon in wheat crop under water limitation and seed tolerance to water stress during germination
ABSTRACT Water stress during wheat seed germination and seedling establishment for affect the percentage and speed of germination. Silicon (Si) is related to plant tolerance to different types of stress, then the application of this nutrient in the mother plant during seed production could contribute to the improvement of the seed quality and, consequently,

3. Aspects of the reproductive biology of Zingiber spectabile (Zingiberaceae)
ABSTRACT Ginger (Zingiber spectabile) is cultivated worldwide as a floriculture and landscaping species. Studies on the biology and floral morphology of this species are important for its improvement; however, they are scarce. We investigated the reproductive biology and floral morphology of gingers grown in a germplasm bank. Floral development was monitored

4. The dark side of the rain: self-pollination setbacks due to water exposure in Pavonia varians Moric (Malvaceae), a species with rain-dependent flowering
ABSTRACT Plants that occur in arid or semi-arid environments may restrict their flowering to the rainy season to ensure water availability for reproductive functions. However, the exposure of flowers to rainfall can compromise their functionality, such as complex self-pollination mechanisms. We experimentally tested how rainfall exposure affects the sequence

6. Characterization of cultivars and low-temperature pollen grain storage in amaryllis (Hippeastrum sp.)
ABSTRACT The determination of viability and the preservation of pollen grains are useful tools for breeding of ornamentals, especially when the synchronization of flowering between species or cultivars does not occur naturally. Thus, the objective of this study was to characterize the flowering and to evaluate the preservation and maintenance of the viabilit

7. Floral biology, pollination requirements and behavior of floral visitors in two species of pitaya
RESUMO O presente trabalho objetivou estudar a biologia floral, os requerimentos de polinização e o comportamento de visitantes florais em duas espécies de pitaia, Hylocereus undatus e H. polyrhizus no Nordeste do Brasil. O experimento foi conduzido com observações diurnas e noturnas e pelo uso de flores ensacadas ou acessíveis aos visitantes. Os resul

8. Changes in leaf appearance and developmental phases associated with breeding progress in six-rowed barley in the Pannonian Plain
Abstract The aim of this study was to analyze traits of leaf appearance and phenological development related to grain yield gain in winter barley cultivars released over the past 50 years. Field trials with 15 six-rowed winter barley cultivars were conducted during two growing seasons. The main leaf appearance and developmental traits were studied. The durat

9. Morphological and physiological changes during maturation of okra seeds evaluated through image analysis
ABSTRACT: This study was performed to associate specific morphological parameters, defined by X-ray images, with seed performance of okra (Abelmoschus esculentus (L.) Moench) during maturation. Fruits of cultivar Santa Cruz 47 at different developmental stages were collected at five-day intervals (from 5 to 65 days after anthesis) and water content, dry matt

12. Physicochemical and microbiological dynamics of the fermentation of the ccn51 cocoa material in three maturity stages
Resumo A dinâmica físico-química e microbiológica durante a fase de fermentação do material de cacau CCN51 foi avaliada em três fases de maturidade (fase 2: 130-152 dias após a antese DDA, fase 3: 153-174 DDA e Fase 4: 175 -196 DDA). Através da técnica da microfermentación foi monitorizado a cada 24h as variáveis físico-químicas (pH, acidez ti
