Nutritive Medium Adsorbent Compensation for Embryo Germination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manufactured seeds containing somatic plant embryos have lower germination rates compared to natural seeds due to the lack of protective and nutritive structures, necessitating an improved nutritive medium for enhanced germination and growth.
Innovation Solution
A method is developed to create an improved nutritive medium by determining the components that decrease in concentration when incubated with an adsorbent material and adjusting their concentrations, along with maintaining the same type of adsorbent material within a two-fold range, to enhance the germination frequency of plant embryos.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manufactured seeds are created using standard nutritive media, then large numbers of genetically identical embryos can be produced, but germination rates are lower compared to natural seeds
Solution Approach 1:
The patent modifies the chemical composition parameters of the nutritive medium by increasing concentrations of specific components (sugars, amino acids, vitamins, minerals) to compensate for adsorbent material that removes nutrients during incubation, thereby improving germination rates while maintaining embryo production capability
Solution Approach 2:
The patent performs preliminary incubation of the nutritive medium with adsorbent material (such as charcoal) before use to predict and compensate for nutrient adsorption, adjusting the initial concentrations of nutrients to ensure adequate availability during actual embryo germination
2Object-affected harmful factors
If adsorbent material is added to the nutritive medium, then harmful substances are adsorbed, but nutrient components decrease in concentration
Solution Approach 1:
The patent converts the harmful effect of nutrient adsorption by adsorbent material into a benefit through predictive incubation and compensation - the same adsorbent material that removes nutrients is used in a controlled preliminary incubation to predict adsorption levels, which then informs the adjustment of initial nutrient concentrations to ensure adequate nutrient availability
Solution Approach 2:
The patent changes the concentration parameters of nutrient components in the nutritive medium to compensate for adsorption losses, specifically increasing sugars, amino acids, vitamins, and minerals to maintain adequate nutrient levels after adsorbent interaction
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 improved nutritive medium significantly increases the germination frequency and normalcy of germinants in manufactured seeds, outperforming standard media, particularly when using non-nutrient-treated charcoal, thereby addressing the limitations of existing manufactured seed technologies.
Implementation Method 1
a first nutritive media comprising a pre-determined initial concentration of components comprising one or more carbon sources, vitamins, minerals and amino acids is incubated with an adsorbent composition to determine if there is a decrease in the concentration of one or more of the components
