INTRODUCTION There are many potential factors that can modulate bronchial reactivity, including exposure to allergens, viral infections, and medications. The aim of this study was to analyze the effect of grass pollination intensity on the bronchial reactivity in seasonal allergic rhinitis (SAR) patients subjected to subcutaneous allergenic immunotherapy (SCIT). MATERIAL AND METHODS This stud...

Soluble sugar accumulation pattern and contents were studied in two Iranian melon cultivars, ‘Suski Sabz’ and ‘Jalali Zard’ (Cucumis melo L. Inodorous). Sucrose, glucose and fructose contents were determined in different mesocarp tissues of developing fruits during days after pollination (DAP). They were characterised by enhanced accumulation of glucose and fructose during early fruit developme...

Pollination is a well-studied and at the same time a threatened ecosystem service. A significant part of global crop production depends on or profits from pollination by animals. Using detailed information on global crop yields of 60 pollination dependent or profiting crops, we provide a map of global pollination benefits on a 5' by 5' latitude-longitude grid. The current spatial pattern of pol...

UNLABELLED PREMISE OF THE STUDY Thermogenesis is a prominent pollination-related feature of cycad cones and is generally assumed to play a role in pollination. Although typically studied just before, during, and immediately after the cones' pollination phase, thermogenesis may be present in other cone developmental phases. • METHODS We assayed thermogenesis in Cycas micronesica, Guam's end...

Abstract Producing seeds from shallot flower requires proper pollination techniques to form pithy seeds. This study aims determine the effectiveness of several methods in producing true (TSS). The research was conducted Cilame Village, Ngamprah District, West Bandung Regency, Java at an altitude 900 m asl. used a completely randomized design (CRD) which consisted four treatments and six replica...

Very low ethylene production rates were measured in nonpollinated Cyclamen persicum Mill flowers, and no change in production was observed during the whole life span of the flower until death. Normal senescence was accompanied by a gradual discoloration and loss of turgor followed by wilting. Pollination induced a dramatic increase in ethylene evolution, culminating in a peak 4 days after polli...

In maize (Zea mays), leaf senescence acts as a nutrient recycling process involved in proteins, lipids, and nucleic acids degradation and transport to the developing sink. However, the molecular mechanisms of pre-maturation associated with pollination-prevention remain unclear in maize. To explore global gene expression changes during the onset and progression of senescence in maize, the inbred...
