Florists’ greens are a very important element of floral compositions, and their vase life must match that the flowers, hence this review presents results research has been conducted over years in order to improve post-harvest longevity species grown for florists’ using growth regulators from groups gibberellins (GAs) cytokinins (CKs). include foliage, leafy non-leafy stems herbaceous plants, tr...

In the present tutorial we address a problem with a long history, which remains of great interest to date due to its many important applications: It concerns the existence and stability of periodic and quasiperiodic orbits in N degree of freedom Hamiltonian systems and their connection with discrete symmetries. Of primary importance in our study is what we call nonlinear normal modes (NNMs), i....
