Multinjerto Madre

Mexicanasseeds Mother Plant Multi-Grafted for Genetic Conservation and Polyploidy Evaluation 1. Rootstock / Base Pattern Genetics: Jarilla Sinaloa (Regular Line / Regional Landrace). Selection Criteria: Selection for hardiness, root vigor, and superior resistance to biotic stresses (pests and pathogens) and abiotic stresses (water and thermal stress). 2. Block A: Conservation of Elite Germplasm (9 Cultivars) Elite clones and stabilized lines grafted for the preservation of genetic reservoir and optimization of space in storage: * Banana OG * Cookies * Gelato * Black Domina * White Kush * GSC (Girl Scout Cookies) * Skywalker OG * Critical Kush * Cheese & Kush

Mexicanasseeds Update: Day 1 of Flowering (Photoperiod 12/12) Project: Genetic Conservation and Phenotypic Evaluation in Multi-Grafted Mother Plant 1. Infrastructure and Environmental Management Location and Facilities: Flowering in outdoor greenhouse. Protection Phytosanitary: High-density anti-thrips mesh for biological exclusion and prevention of virus vectors. Radiation Management: 30% Raschel shade mesh for managing photosynthetically active radiation (PAR), reducing infrared radiation and mitigating thermal stress in the canopy. 2. Substrate Physics and Root Zone Substrate Composition: Inert coconut mix in a 50/50 ratio: 50% Coconut Chips: Provides macroporosity, aeration, and prevents compaction. 50% Coconut Fiber (medium grain size): Uniform water retention and optimal Cation Exchange Capacity (CEC). Rootstock Base: Jarilla Sinaloa (regional landrace), leveraging its high root exploration vigor to maximize metabolic absorption in the substrate structure. 3. Fertigation and Hydroponics Parameters Application System: Drip irrigation with 8 micropulses per day, automated with high precision. Nutrition: Internal formulation hydroponic solution, adjusted to the morphogenetic requirements of the beginning of flowering (stretch). pH Range: 5.8 – 6.0 (sweet spot for the bioavailability of phosphorus, calcium, magnesium, and chelated micronutrients). Water / Solution Temperature: Constant 24 °C to ensure optimal levels of dissolved oxygen (DO) and avoid thermal shock in the rhizosphere. Leaching Fraction (Drainage): 20% drainage per irrigation event, ensuring continuous washing of excess sales in the wet bulb and allowing for accurate monitoring of output EC. 4. Canopy and Grafts Status (9 Varieties): Elite Germplasm Conservation (9 Clones) Banana OG, Cookies, Gelato, Black Domina, White Kush, GSC, Skywalker OG, Critical Kush, Cheese & Kush. 5. Vascular Consolidation and Transition 100% consolidation of xylem and phloem tissues at graft junctions. Complete water stabilization under the flow pressure of the drip system, ensuring uniform supply of the nutrient solution to each of the arms during initial elongation.
