LATESWEET XXI Plum Tree Cross-Pollination and Fruit Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new variety of plum tree that is self-unfruitful and requires cross-pollination, producing smaller, sweeter, and more flavorful fruit with improved pollination efficiency, while being hardy and productive for commercial orchards in central California's climate.
Innovation Solution
The 'LATESWEET XXI' plum tree variety, derived from crossing 'September Yummy' with apricot and interspecific hybrid trees, is self-unfruitful, requires cross-pollination, and exhibits enhanced pollination with a heavy bloom, producing smaller, sweeter, and more flavorful fruit, suitable for commercial cultivation and long-distance shipping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the plum tree is self-unfruitful and requires cross-pollination, then pollination efficiency can be improved through heavy bloom and abundant pollen, but the complexity of pollination management increases
Solution Approach 1:
The tree produces a very heavy bloom with an abundant amount of pollen to entice good bee activity, effectively using its own resources (pollen production) to facilitate self-pollination and reduce dependence on external pollination management interventions
Solution Approach 2:
The patent utilizes bee activity as an intermediary to transfer pollen between flowers, leveraging natural pollinator behavior to achieve effective cross-pollination without requiring complex人工 pollination management systems
2Manufacturing precision
If the fruit is smaller in size and sweeter in flavor, then quality is improved, but the quantity of fruit per tree decreases
Solution Approach 1:
The patent changes the fruit development parameters by extending the maturity period (about fifty days later than seed parent) and controlling growing conditions to produce smaller, sweeter fruit with improved flavor and texture, accepting reduced quantity in exchange for enhanced quality
3Adaptability or versatility
If the tree is hardy and productive for commercial orchards, then adaptability to central California climate is improved, but the specificity to particular ecological conditions increases
Solution Approach 1:
The patent develops the variety with specific local adaptations to central California's climate and ecological conditions, optimizing traits such as hardiness, vigor, and fruit maturity timing for this particular region while maintaining sufficient adaptability for commercial cultivation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The 'LATESWEET XXI' plum tree variety ensures effective pollination, produces high-quality fruit with improved flavor and texture, and maintains good shipping quality, remaining in good condition for up to 30 days, making it suitable for fresh market and long-distance shipping.
Implementation Method 1
Being self-unfruitful, the present variety requires cross pollination from an apricot, interspecific, or plum that blooms during the mid to late season
Implementation Method 2
The present variety produces a very heavy bloom with an abundant amount of pollen to entice good bee activity to facilitate pollination
Implementation Method 3
The fruit matures under the ecological conditions described during the first week of November, with first picking on Nov. 2, 2011

AI summary
The present invention relates to an interspecific tree and more particularly to a new and distinct variety broadly characterized by a small size, moderately 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 mid to late season. The present variety produces a very heavy bloom with an abundant amount of pollen to entice good bee activity to facilitate pollination. The fruit matures under the ecological conditions described during the first week of November, with first picking on Nov. 2, 2011. The fruit is uniformly medium in size, very deep red in skin color, clingstone in type, globose to slightly oblong in shape, yellow in flesh color, firm in texture, and excellent in flavor.
