Producing seedless fruits could improve food security
According to newly released research, the production of seedless fruits is an under-estimated tool for improving food security. The opportunity to produce bountiful levels of vital food crops such as apples, tomatoes and watermelons could be boosted by reducing a crop's demand for pollinators, new research has shown.
A team of researchers from the University of Exeter have conducted new research into how plant breeders are striving to improve fruit yields from crops, across the globe, by bi-passing the plants' need for insect pollination to reproduce.
This is done by inducing parthenocarpy - artificially or via genetic modification - which makes a plant produce seedless fruits without the need for pollination. The study shows that parthenocarpy increases fruit quality and quantity amongst crops that would otherwise require pollination.
However, the team insist parthenocarpy should not be used as a "panacea for agricultural success" - but should sit alongside environmentally sound practices to boost pollinator populations.
The research was published in the respected Journal of Applied Ecology on the 11th November.
Jessica Knapp, lead author of the paper and from the Environment and Sustainability Institute, based at the University's Penryn Campus in Cornwall said: "It is of course vital that we still encourage and increase our native pollinator populations to ensure crops and wild plants can thrive as much as possible.
"However, parthenocarpy can increase the quality and quantity of vital crops, such as apples and tomatoes, which may struggle to be pollinated naturally".
The pioneering study presented a meta-analysis of existing studies to examine the extent and effectiveness of parthenocarpy-promoting techniques which include genetic modification, hormone application and selective breeding.
The study showed that all the techniques increased fruit quantity and quality in 18 crops that traditionally depend on pollinators. Consequently, parthenocarpy could improve fruit quality and quantity in conditions usually adverse for pollination, such as during periods of poor light or cooler temperatures.
The researchers believe the study shows that parthenocarpic crop plants could allow producers to extend growing seasons, increase the resilience of crops to adverse conditions, and ultimately improve food security.
