Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current plum tree varieties face challenges in self-unfruitfulness, requiring cross-pollination and having limited adaptability to different ecological conditions, which affects fruit quality and shipping efficiency.
Innovation Solution
Development of the 'LATESWEET XX' interspecific plum tree variety, which is self-unfruitful and requires cross-pollination, producing darker red, sweeter, and oblate fruit with improved heat and drought tolerance, and enhanced bee pollination, facilitating better pollination and fruit quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plum trees are made self-unfruitful to require cross-pollination, then fruit quality and genetic diversity are improved, but pollination complexity and production reliability deteriorate
Solution Approach 1:
The patent introduces bee hives as intermediary agents to facilitate cross-pollination between self-unfruitful plum trees. The bees act as mediators that transfer pollen between trees, enabling fruit production without direct human intervention in the pollination process. This resolves the contradiction by maintaining self-unfruitfulness for genetic diversity while using bees as intermediaries to manage the pollination complexity.
Solution Approach 2:
The plum trees are designed to produce abundant nectar and pollen that actively attract and sustain bee populations in the orchard. The system becomes self-sustaining where the trees' own floral resources provide the service of pollination through the attracted bees, eliminating the need for external pollination management while maintaining cross-pollination benefits.
2Adaptability or versatility
If plum trees are made self-unfruitful to require cross-pollination, then genetic diversity and adaptability are improved, but pollination management difficulty increases
Solution Approach 1:
The plum variety produces abundant nectar and pollen that automatically attract and sustain bee populations, creating a self-managing pollination system. The trees' floral characteristics serve as the mechanism for both achieving genetic diversity through cross-pollination and simplifying pollination management by eliminating the need for human intervention in the pollination process.
3Productivity
If heavy bloom with abundant pollen is produced to entice bee activity, then pollination effectiveness is improved, but energy consumption and resource allocation worsen
Solution Approach 1:
The heavy bloom and abundant pollen production serves a dual function: it attracts bees for effective pollination while simultaneously providing food resources that sustain the bee population throughout the orchard. This self-service approach converts what would be pure energy expenditure into a resource investment that maintains the pollination service providers, improving the energy efficiency of the overall system.

AI summary
The present invention relates to an interspecific tree and more particularly to a new and distinct variety broadly characterized by a medium size, vigorous, hardy, and very productive tree. Being self-unfruitful, the present variety requires cross pollination from an apricot, interspecific, or plum that blooms during the late season. The present variety produces a very heavy bloom with an abundance of pollen to entice good bee activity to facilitate pollination. The fruit matures under the ecological conditions described during the last half of October, with first picking on Oct. 23, 2011. The fruit is uniformly medium in size, very dark red to purple in skin color, semi-clingstone in type, globose to oblate in shape, yellow in flesh color, firm in texture, and excellent in flavor.
