Blackred V Interspecific Plum Tree Pollination and Maturity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plum tree varieties face challenges in self-pollination, with limited bloom and pollen production, leading to reduced fruit set and delayed maturity, which affects shipping quality and efficiency.
Innovation Solution
The development of the 'Blackred V' interspecific plum tree variety, which is self-unfruitful and requires cross-pollination, exhibits a more prolific bloom, increased pollen production, and earlier maturity, ensuring effective pollination and fruit development.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the plum tree variety is self-unfruitful and requires cross-pollination, then pollen production and bloom prolificacy are improved, but pollination complexity and dependency on external pollinators increase
Solution Approach 1:
The patent introduces bees as intermediary pollinators to transfer pollen between trees. The 'Blackred V' variety produces abundant pollen that attracts strong bee activity, which then facilitates cross-pollination to other compatible plum varieties, resolving the contradiction between high pollen production and pollination complexity by using nature's intermediary pollinators
Solution Approach 2:
The variety's abundant pollen production and prolific bloom essentially service themselves by attracting pollinators naturally. The tree doesn't require external intervention beyond providing the pollen and bloom resources that attract bees, which then perform the pollination function automatically
2Loss of time
If the variety matures earlier, then shipping quality and productivity are improved, but fruit development time is reduced
Solution Approach 1:
The patent achieves earlier maturity by changing the genetic parameters of the plum variety through interspecific hybridization. The 'Blackred V' variety combines genetic traits from different plum species that result in accelerated fruit development while maintaining quality, reducing maturity time by 25 days compared to similar varieties without compromising fruit development adequacy
3Reliability
If cross-pollination is required, then fruit set quality is improved, but self-pollination capability is lost
Solution Approach 1:
Instead of relying on self-pollination, the patent inverts the approach by making the variety self-unfruitful and dependent on cross-pollination. This inversion ensures higher fruit set quality through genetic diversity from cross-breeding, accepting the loss of self-pollination capability as a trade-off for improved fruit reliability

AI summary
The present invention relates to an interspecific tree and more particularly to a medium size, vigorous, hardy, and productive tree. The present variety has a prolific bloom during the early to mid season, is self-unfruitful, but produces an abundance of pollen to entice bees to facilitate pollination. The fruit matures under the ecological conditions described during early July, with first picking on Jun. 30, 2007. The fruit is uniformly medium in size, blackish red in skin color, clingstone in type, globose to obovate in shape, dark red in flesh color, firm and crisp in texture, and outstanding in flavor.
