The global cycle of the seeds.
.1 In the seeds at rest with respect to the Earth, the two alternating processes - during which the seeds first reduce their viability, and then recover it - depend on the variation of the angular velocity of the Moon phase with respect to the Earth (not with respect to the seeds).
See the definition of “moon phase velocity”.
.2 When that velocity is decreasing, also the viability in seeds tend to decrease (periods of the “hard seeds”).When it increases (periods of the “tender seeds”), seeds tend to recover their lost viability, at the times when all constraints are satisfied.
.3 I name this alternation "global cycle of the seeds", because I presume it is operative everywhere, while the times of the other two cycles of the seeds so far discovered, treated later, could depend on the location.
.4
One instance of global cycle (measured in units of 1/600 of degree /hr, here called deltins). This applies to the seeds at rest with respect to the Earth.
appendix ‘c’:

Current times of the global cycle of the seeds.
Periods of the hard seeds.
.5 If at rest with respect to the Earth, the seeds reduce the degree of their viability during the periods b-c and d-a. Their ability to germinate either becomes reduced, or is suspended.
Periods of the tender seeds.
.6 While, during the periods a-b and c-d, the seeds may - at given costraints - restore their dotation of orderly EFAs, and thus the degree of their viability.
Days of reduced viability.
.7 During the last days of the periods b-c and d-a, particularly if those periods have a long duration, and above all if temperature is high, some seeds - such as those of wheat - have their dotation of orderly EFAs reduced, though usually still above the germinability threshold.
.8 As a consequence, they find themselves partially inhibited, with a low degree of available viability. Though they are still able to germinate, they could do so at a disadvantage.
.9 If the seeds germinate when their degree of viability is low, the life and yield of the plants would be affected, particularly if they have to undergo adverse conditions, such as a period of drought.
Days of suspended viability.
.10 Some kinds of seeds, e.g. linseeds, go under the viability threshold, after just 6-7 hard seed days (period b-c, or d-a), if kept at temperature of the order of 27-35°C (it depens on their state at the beginning of the period).
.11 Their ability to germinate is temporarily suspended; it will be restored only at the beginning of the following period of tender seeds (either a-b, or c-d).
.12 The experiment ‘C’ is intended to prove it.

[see annex: “Experiment C” (Have seeds at rest with respect to the Earth to germinate)]

If the Moon ceased to exist.
.13 The seeds show to be able, at given conditions, to restore their orderly EFAs dotation, though only if a mass of matter moves around them, very slowly.
.14 For the seeds at rest with respect to the Earth, there is only one moving mass of matter, sufficiently large and near: the Moon.
See the physical formula to be applied here in the “insert D”, at the page 4, §3.
.15 If the Moon ceased to exist, all the seeds which rely on their contents of orderly EFAs for their available viability, probably all of them, as they are usually at rest with respect to the Earth, would lose their EFAs endowment in a short time, with no chance to restore it at a later period; eventually, they would be no longer able to germinate.
