1) What makes that just the last buds, or just the last opened flowers on flower twig fade and die, while others below are apparently keeping health?. (Seen on my Odontoglosum and aldo on Cymbidium.)

2) Whay makes that just the keikis, and not the rest of the plant, show a quick dacay on their leaves, going quickly from normal green leaves to yellow and then fall?: (seen on a my Dendrobium and on my oncidium).

Not knowing your growing conditions, I'll try to answer your questions.

Two things come to mind. Transient changes in the environment, such as
standing in a draft, changes (usually a decrease) in ambient humidity, or a
rise in temperature. Also changing the plant's environment, like bringing
it in the house from the greenhouse or outside. The developing buds will
'blast' and the more developed ones will remain fresh.

I think its part of the same thing. The keiki out in the air doesn't have
the same support that the mother plant has (from its roots being in some
sort of medium that gives the plant water and humidity , as well as the
resource of water stored in back bulbs that can be pulled when needed to get
it over these fluctuations that occur in its environment) They dry and fall
off.

Thank you for your answers. I think the are great.

I have, impatiently I know, given a cut to the top of the two Dendrobium's keikis (a little bit below the basement of the fallen leaves). My asumption (right or wrong): Just to let the plant concentrate on adapting itself by the strong parts rather than on trying to save weaker extensions. What do you think? Will these keikis have a future, anyhow?

I think you are right to cut off the keiki. I agree that the keiki won't
have much of a future. My advice is to concentrate on getting the mother
plant to flower for you, instead of spending your (and the plant's) time and
energy on the keikis.
