What are: day leaf, flower, fruit, root ? (Sidereal rhythm)

By effecting its rotation around the earth each month the Moon passes in front of the 12 constellations of the astrological zodiac, as does the sun in one year. The sidereal rate is the period between two successive passages of the Moon before the same group of stars (hence the adjective sidereal) zodiac. It lasts 27.3 days
The use of this rhythm was popularized by Maria ThunAg who proceeded to daily radish seedlings in poor soil and no irrigation. She would have found morphological variations, with parts of the plant more or less stimulated by the day in question, and supposed influence of the zodiac constellation of the time of sowing.
Conversely the plants belong to either of these categories in that part of the plant used: then it must sow them and care for them in preference to day : sheet, fruit, flower or root.
