Semiotic-Mathematical Modeling of the Critical Phase of Symbiotic Orchid Seed Incubation

This paper presents a semiotic reading of the inverse quadratic function f(x) = -x^2 + 45x + 1/4 in the context of symbiotic orchid seed incubation. This study does not claim a new mathematical function. It does not claim a physical or biological law. The function above is a standard parabola. What is proposed is a semiotic framework for reading this structure. In this framework, 45 is the general semiotic anchor, 22.5 is the vertex / axis of symmetry, and 506.5 is the peak value. These numbers are signifiers. Their signified is determined by the context of the case. In this orchid case, the signifier 22.5 is read as 22.5°C, the upper maximal bound of dark condition, and the signifier 506.5 is read as 506.5 hours, pointing to the corridor of Day 21, the moment of seed coat rupture (Stage 0). In the laboratory, the standard incubation is 4 weeks. For ideal research, the critical period should be extended to 4.5 weeks because of the STERILE HANGING PHASE. At 4.5 weeks, the seed has already ruptured and the Proto Meristem (the First Shoot Primordium) has not yet emerged (0% protocorm). As a comparator, this paper uses the general orchid literature (Arditti, 1967), which writes the temperature as 20-22°C in dark condition and 24-26°C in light condition. Because the abstract of this study writes 21°C, the condition read here is the dark condition. Semiotics reads: 506.5 hours = 21.1 days, SELARAS (in harmony) with Day 21. 22°C = Maximum Temperature in Dark Condition. 22.5°C = Upper Maximal Bound.
