Hydrangea HISUN Cultivar Stem Strength and Flower Longevity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Hydrangea macrophylla cultivars lack sturdy and strong plants with attractive inflorescences and good post-production longevity, which are essential for durable and long-lasting floral displays.
Innovation Solution
A new cultivar, 'HISUN', resulting from a cross-pollination between proprietary selections of Hydrangea macrophylla, exhibiting upright and spreading growth, strong stems, dense white inflorescences, and prolonged flower longevity, achieved through asexual reproduction by terminal vegetative cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional Hydrangea macrophylla cultivars are used, then they can be grown and reproduced, but they lack sturdy and strong plants with attractive inflorescences and good post-production longevity
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic parameters that result in improved stem strength and post-production longevity. The cross-pollination between selected parents (code 1676 and code 1695) combines desirable traits, producing offspring with enhanced structural strength and durability that exceed conventional cultivars.
2Strength
If Hydrangea plants are bred for sturdy stems and strong growth, then plant strength improves, but inflorescence attractiveness and post-production longevity may be compromised
Solution Approach 1:
The patent merges multiple desirable traits by cross-pollinating two proprietary selections, each contributing specific advantages. The female parent (code 1676) and male parent (code 1695) are selected for complementary characteristics, and their offspring combine both strong stem development and excellent post-production longevity, resolving the trade-off between strength and reliability.
3Productivity
If conventional breeding methods are used, then existing cultivars are maintained, but new varieties with improved综合 performance are not developed
Solution Approach 1:
The patent applies preliminary action by conducting systematic preliminary breeding work involving selective cross-pollination of carefully chosen parent plants. This preliminary breeding program, executed before commercial production, establishes the genetic foundation for improved cultivars that simultaneously achieve commercial suitability and enhanced performance characteristics.
