Design of Stickbug: a Six-Armed Precision Pollination Robot [PDF]

open access: yesarXiv
This work presents the design of Stickbug, a six-armed, multi-agent, precision pollination robot that combines the accuracy of single-agent systems with swarm parallelization in greenhouses. Precision pollination robots have often been proposed to offset the effects of a decreasing population of natural pollinators, but they frequently lack the ...

The pollination of tomatoes.

open access: yesNetherlands Journal of Agricultural Science, 1957
Studies were carried out on the effect of pollination on fruit set, normal fruit growth, earliness of yield and size of fruit. A high positive correlation was found between the number of seeds per fruit and the fruit weight. When flowers were pollinated with a mixture of inert powder and pollen, fruits were larger and earlier as the proportion of ...

Towards Closing the Loop in Robotic Pollination for Indoor Farming via Autonomous Microscopic Inspection [PDF]

open access: yesarXiv
Effective pollination is a key challenge for indoor farming, since bees struggle to navigate without the sun. While a variety of robotic system solutions have been proposed, it remains difficult to autonomously check that a flower has been sufficiently pollinated to produce high-quality fruit, which is especially critical for self-pollinating crops ...

More than symbioses : orchid ecology ; with examples from the Sydney Region [PDF]

open access: yes, 2013
The Orchidaceae are one of the largest and most diverse families of flowering plants. Orchids grow as terrestrial, lithophytic, epiphytic or climbing herbs but most orchids native to the Sydney Region can be placed in one of two categories.

Ontogenetic shifts in olfactory rosette morphology of the sockeye salmon, Oncorhynchus nerka

open access: yesJournal of Morphology, Volume 284, Issue 1, January 2023., 2023
Scanning electron microscope images of sockeye salmon olfactory rosette. Olfactory rosette size linearly increases with lamellae number throughout ontogeny. The complexity of the rosette, including the distribution of sensory and nonsensory epithelia, and the appearance of secondary lamellar folding, varies between fry and adult life stages.

Enhancement of developmental defects in the boron‐deficient maize mutant tassel‐less1 by reduced auxin levels

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView., 2023
Abstract Background Plant responses to deficiencies of the micronutrient boron are diverse and go beyond the well‐characterized function of boron in cell wall crosslinking. To explain these phenotypic discrepancies, hypotheses about interactions of boron with various phytohormones have been proposed, particularly auxin.

Addition of nocturnal pollinators modifies the structure of pollination networks

open access: yesScientific Reports
AbstractAlthough the ecological network approach has substantially contributed to the study of plant-pollinator interactions, current understanding of their functional structure is biased towards diurnal pollinators. Nocturnal pollinators have been systematically ignored despite the publication of several studies that have tried to alleviate this ...
