Background and Aims: Climate variation contributes to fluctuations in reproductive output, and spring temperature is thought to influence flower production in grapevines. For 3 years, we studied the influence of temperature from before budswell through to the appearance of individual flowers on reproductive development in field-grown Cabernet Sauvignon while minimising the influence of other mi...

Recent phylogenetic reconstructions suggest that axially condensed flower-like structures evolved iteratively in seed plants from either simple or compound strobili. The simple-strobilus model of flower evolution, widely applied to the angiosperm flower, interprets the inflorescence as a compound strobilus. The conifer cone and the gnetalean 'flower' are commonly interpreted as having evolved f...

Changes in gene expression during flower formation were studied in the long-day plant Sinapis alba. The day length dependence was exploited to synchronize flower formation in a large population of mustard plants. After an inductive light treatment, apices were harvested after different lengths of time, and changes in gene expression were analyzed. Two major groups of genes were identified whose...

In the area of agricultural field, the accurate forecasting of the yield and their estimation from the raw data are playing the important role in the planning of various aspects of agricultural production. In this paper an attempt has been made to estimate flower yield which helps in providing the knowledge so that it creates the base for flower marketing and its management. The main aim of thi...

Many insects foraging for nectar or pollen exhibit flower constancy, a learned fidelity to a particular species of plant that previously provided a reward. Constancy may persist even when alternative flowers are available that provide a greater or less variable reward. This strategy entails more travelling time than one of generalization (visiting all suitable flowers as they are encountered). ...

Chain-like Co flower is synthesized by simply modulating the reaction conditions via a facile liquid-phase reduction method. The morphology evolution process and transformation mechanism from particle to flower and finally to chain-like flower have been systematically investigated. [001] is the preferred growth orientation due to the existence of easy magnetic axis. The microwave loss mechanism...

Flower strips are commonly recommended to boost biodiversity and multiple ecosystem services (e.g., pollination and pest control) on farmland. However, significant knowledge gaps remain regards the extent to which they deliver on these aims. Here, we tested the efficacy of flower strips that targeted different subsets of beneficial arthropods (pollinators and natural enemies) and their ecosyste...
