As we saw in the itinerary 1.1, the germinability of seeds can be increased, in order to get large yields.

In this itinerary, I describe the series of observations and experiments that led me to understand the two phases of the cumulative-dissipative thermodynamic cycle, which allows the seeds to keep themselves viable for a long time. Thanks to this cycle, they recover degrees of germinative capacity from time to time.

Observations and experiments also led me to understand how to proceed before sowing, in order to bring the cumulative phase into agreement with the required heat exchanges, so as to make the processes of the dissipative phase more efficient, instead of leaving everything to chance.

The chance in the life of a plant.

Sowing seeds is an aleatory contract that one stipulates with the Nature. It’s up to us to make this contract less aleatory.

It is rare that a seed starts its germination when it is in the best possible condition. The chance has a dominant role to determine the degree of viability of a seed, just at the crucial time, when it counts most, when it starts its germination. This will have far reaching implications throughout the life of the plant.

Indeed, the degree of viability, at the moment a seed starts its germination processes, is paramount. It is among the main factors which determine the growth of the plant, the development of its root apparatus, so useful to face up to periods of drought. It also improves its resilience, and ultimately its final productivity, and, in the case of a tree, its longevity. All the other variables being equal.

It is a blind bet to sow seeds without taking into consideration how the degree of viability varies, in agreement with their cumulative-dissipative cycle.

Instead of getting the germination to start does not matter when, it is better to operate when the viability is in the recovery phase, in accord with the seed viability cycle.

This study is meant as my contribution to this purpose.

Reducing hazards.

The knowledge of the times of the seed viability cycle, and of all the other variables which affect the seeds, may help, to some extent, in the management of the hazards.

In short, operating in accordance with the times, during which the germination capacity of the seeds varies, greatly reduces the randomness, and improves the final results.

The behaviour of the seeds.

It was sunflower seeds that made me understand how they keep germinable for a long time. It is thanks to their movement relative to other matter, at critical angular speeds.

It also served what was observed in flax seeds, maize, wheat, oilseed rape, according to what can be observed and tested, with respect to their respective own peculiarities.

Generally, what is said of these seeds, most likely, should be extended also to other seeds, mutatis mutandis.
