“…In these confines pollination is enhanced with manually vibration of each plant by hand (Freitas et al . ), vibration from a supporting structure (Short & Bauerle ) through the use of vibrating wands (Massa et al . ), vibrating tables or air blast devices that promote pollination as anthers dehisce.…”

“…Techniques have been defined for greenhouses and extra-terrestrial environments where bees are not an option (Schubert 2017). In these confines pollination is enhanced with manually vibration of each plant by hand (Freitas et al 2015), vibration from a supporting structure (Short & Bauerle 1973) through the use of vibrating wands (Massa et al 2015), vibrating tables or air blast devices that promote pollination as anthers dehisce. Selection of specific flower types may enhance amenability to mechanical, non-insect pollination.…”

Agricultural production in controlled environments is increasingly feasible, and may play an important role in providing nutrition and choice to growing urban centres. New technologies in lighting, ventilation, robotics and irrigation are just a few of the innovations that enable production of high-value specialty crops outside of a traditional field setting. However, despite all of the advances in the hardware within the plant factory operation, innovation of the most complex machine has been neglected - the plant itself. Indoor agricultural operations typically rely on legacy varieties, plants selected and bred for field conditions. In the field, phenotypic stability is paramount, as production must be consistent in an unpredictable and changing environment. However, the controlled environment affords focus on different breeding priorities as environmental flux, pests, pathogens and post-harvest quality are less formidable barriers to production. On the contrary, breeding for controlled environments shifts the focus to a completely different set of plant traits, such as rapid growth, performance in low light environments and active manipulation of plant stature. Instead of breeding for phenotypic stability, plants may be bred to maximise genetic plasticity, allowing specific traits to be presented as a function of the quality of the ambient light spectrum. In this scenario plant varieties may be grown with optimal size, supporting a focus on consumer traits like flavour or accumulation of health-related compounds. Gene editing may be a central technology in the production of designer plants for controlled environments. This review considers the opportunity for breeding for controlled environments, with a focus on a revision of priorities for controlled-environment breeders.

“…Other studies investigating tomatoes and eggplants (also buzz-pollinated) also found that tapping of the trellis wires improved fruit set and seed number compared with untreated plants, however the effects were significantly inferior compared with bee pollinated trials [79,80]. Conversely, studies using other Solanaceae crops (eggplants and sweet peppers) found no significant effect of trellis tapping on seed set and fruit weight, across multiple cultivars and treatment groups (e.g., untreated plants, and indoor and outdoor grown crops) [72,81]. The efficacy of the technique seems to vary across cultivars and growth environments, with different costs to the industry (Table 2).…”

“…Vibrating probes can be used to oscillate the staminal cone to elicit pollen expulsion (Figure 7) [20]. Artificial vibrations of individual inflorescences have been reported to increase fruit weights by 10-17% in open field systems [72] and overall fruit yield by 75% in greenhouse production [25], when compared with non-treated controls. Electric toothbrushes (Figure 7) have also been reported to achieve comparable results to tuning fork treatments, noting that the effect of frequency on pollination outcomes was negligible but was more dependent on the buzzing duration and plant species [73].…”

Precision Pollination Strategies for Advancing Horticultural Tomato Crop Production

Global climate change and anthropological activities have led to a decline in insect pollinators worldwide. Agricultural globalisation and intensification have also removed crops from their natural insect pollinators, and sparked research to identify alternate natural insect pollinators and artificial technologies. In certain countries such as Australia the importation of commercial insect pollinators is prohibited, necessitating manual labour to stimulate floral pollination. Artificial pollination technologies are now increasingly essential as the demand for food grown in protected facilities increases worldwide. For tomato fruits, precision pollination has the ability to vastly improve their seed set, size, yield, and quality under optimal environmental conditions and has become financially beneficial. Like many crops from the Solanaceae, tomatoes have a unique self-pollinating mechanism that requires stimulation of the floral organs to release pollen from the poricidal anthers. This review investigates various mechanisms employed to pollinate tomato flowers and discusses emerging precision pollination technologies. The advantages and disadvantages of various pollinating technologies currently available in the protected-cropping industry are described. We provide a buzz perspective on new promising pollination technologies involving robotic air and acoustic devices that are still in their nascency and could provide non-contact techniques to automate pollination for the tomato horticultural industry.
