Physiology of flower initiation
TLDR
The central problem of the physiology of flower initiation is to understand which factors cause a shoot meristem to become a flower primordium, and how they consummate their action.

Promotion and inhibition of flower formation in a dayneutral plant in grafts with a short-day plant and a long-day plant.
TLDR
The former results indicate transmission of flower-promoting material(s) from photoperiodic plants maintained under flower- Promoting daylength conditions to a dayneutral graft partner; the latter indicate the presence in the long-day plant N. silvestris under short-day conditions of potent flower-inhibiting and growth-regulating material (s) that can also be transmitted to aday-neutral partner.
Gibberellins: Structure and Metabolism
TLDR
This review looks at the GAs themselves: their chemical structure, their biogenesis, transport, conversions, and a few related prob­ lems such as the so-called bound GAs.
Lettuce Seed Germination: Evidence for a Reversible Light-Induced Increase in Growth Potential and for Phytochrome Mediation of the Low Temperature Effect.
TLDR
It has been proposed that promotion by gibberellic acid an(l kinefin is effecte(d via (lifferent mechanlisms, neither of which is the samiie as that for l)rolllotion l)y R, to eluicidlate the germination-prolimotinig effect of low templerature.
Effects of some internal and external conditions on seed germination
TLDR
The present chapter and the following one will deal with the physiology of seed germination as such, i.e. seeds which are fully able to germinate as soon as given the conditions directly necessary for activity and which may be called quiescent seeds.
The growth physics and water relations of red-light-induced germination in lettuce seeds
TLDR
Results showed that the water potential of red-light-treated embryos was lower than that of dark-treated ones, the difference being equivalent to the potential of a 0.30 molal mannitol solution.
