Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for evaluating citrus fruit cracking are inadequate, lacking quantitative indicators that can accurately reflect the relationship between fruit cracking, variety, management level, and environmental factors, and fail to comprehensively assess the impact of various contributing factors such as water management, climatic conditions, nutritional imbalance, and pests/diseases.
Innovation Solution
A method utilizing five indicators: peel hardness, fruit turgor pressure, fruit cracking site at turgor pressure limit, injected water volume at turgor pressure limit, and cracked fruit proportion index, along with a scoring system to quantify fruit cracking, enabling a comprehensive evaluation of citrus fruit cracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If field observation method is used to evaluate citrus fruit cracking, then the evaluation process is simple, but the measurement precision is insufficient to reflect the relationship among variety, management level, and environmental factor
Solution Approach 1:
The patent transforms the qualitative field observation into quantitative measurement by introducing five specific physiological parameters (peel hardness, fruit turgor pressure, fruit cracking site at turgor pressure limit, injected water volume at turgor pressure limit, and cracked fruit proportion index). This allows the evaluation to maintain operational simplicity while achieving precise quantitative assessment of fruit cracking susceptibility.
Solution Approach 2:
The patent replaces the subjective mechanical field observation with objective physiological parameter measurement. By using instruments to measure peel hardness, turgor pressure, and other physiological indicators, the evaluation transitions from rough visual assessment to precise quantitative measurement, resolving the contradiction between simplicity and accuracy.
2Device complexity
If single fruit cracking rate is used as indicator, then the evaluation method is simple, but the measurement precision is insufficient to comprehensively evaluate the fruit cracking problem
Solution Approach 1:
The patent divides the single fruit cracking rate indicator into five distinct physiological parameter indicators: peel hardness, fruit turgor pressure, fruit cracking site at turgor pressure limit, injected water volume at turgor pressure limit, and cracked fruit proportion index. Each indicator measures a specific aspect of fruit cracking susceptibility, providing comprehensive evaluation while maintaining manageable complexity through clear segmentation of measurement tasks.
3Measurement precision
If quantitative indicators are introduced to evaluate citrus fruit cracking, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The patent measures five specific physiological parameters (peel hardness, fruit turgor pressure, fruit cracking site at turgor pressure limit, injected water volume at turgor pressure limit, and cracked fruit proportion index) that directly reflect fruit cracking susceptibility. By focusing on these key physiological parameters rather than attempting to measure all possible factors, the system achieves high measurement precision while keeping the evaluation framework manageable and systematic.

Function Achieved in This Case
The method provides a quantitative assessment of citrus fruit cracking, correlating these indicators with fruit cracking rates, allowing for a deeper understanding of the causes and facilitating effective measures to reduce cracking through breeding and cultivation practices.
Implementation Method 1
the fruit turgor pressure is a pressure value produced inside a citrus fruit when the citrus fruit cracks due to water injected into the citrus fruit from a central axis of the citrus fruit

AI summary
Provided is a method for evaluating citrus fruit cracking. In the method, five indicators for evaluating citrus fruit cracking are determined and subjected to correlation analysis with field experiment data of fruit cracking rates of citrus fruits, and analysis results show that these five indicators are positively correlated with a cracking rate of fruits. By detecting these five indicators, the correlation of fruit cracking characteristics with a variety and cultivation conditions can be accurately described to fundamentally understand a cause for fruit cracking. In addition, it is convenient to determine the five indicators, and the five indicators can be detected in both fruits on a fruit tree and picked fruits. The method provides a technical support for improving the fruit cracking characteristics of a variety through breeding or guiding measures for controlling the fruit cracking including application of a specified fertilizer or reduction of a watering quantity.
