The autonomous pathways for floral inhibition and induction

2007
AbstractThe autonomous pathways for floral inhibition and induction are central to the entire process of floral transition in Arabidopsis. The floral inhibition pathway acts throughout the plant's life to ensure flowering does not occur until the appropriate environmental, developmental, and physiological cues have been received. The inhibition pathway

Floral Induction of Bromeliads by Ethylene

1989
It is common knowledge that ethylene can be used as forcing agent of the flowering process in bromeliads such as pineapple (Ananas comosus L. Merr.).

Floral induction in woody angiosperms

New Forests, 1997
The long juvenile period of trees is a severe impediment to study of reproductive biology and genetic inheritance, and is a serious constraint for traditional breeding programs. Very little effort has been directed toward the development of practical methods for inducing early flowering in most woody angiosperms, particularly members of the genus ...

Floral induction and development in Phalaenopsis in vitro

Plant Cell, Tissue and Organ Culture, 1995
Adventitious shoots formed from nodal sections of floral-stalks of Phalaenopsis Pink Leopard ‘Petra’ that had been propagated on Hyponex medium with 6-benzyladenine (BA). After subculturing adventitious shoots on Vacin-Went medium with BA, more than 70% of the shoots formed floral buds, and 10% of the floral buds flowered in 9-month-old shoots.

Floral induction in conifers: a review of available techniques

Forest Ecology and Management, 1987
During the last 10 years the use of gibberellins, mainly GA47, has greatly improved our ability to induce precocious and more regular flowering of conifers. This paper reviews the current techniques used for floral induction as well as adjunct treatments used to enhance the gibberellin-induced flowering.

Floral induction in Brachypodium distachyon [PDF]

, 2012
Brachypodium distachyon (L.) P. Beauv. is a recently fully-sequenced monocot plant, very closely related to wheat and barley, and an attractive model system to study the biology of temperate cereals. The present work investigates the “mechanisms” of flowering time in Brachypodium (community standard line Bd21) by analyzing a group of core genes, mostly

DWARFING AND FLORAL INDUCTION IN VITIS VINIFERA

Acta Horticulturae, 2012
As grapevine flowering has a major impact on the yield of vines there has been much interest in understanding the biology behind this important developmental process. The study of flowering in grapevine provides some unique challenges due to the unusual shoot architecture of the plant and the extension of the process over two growing seasons.

Possible Role of Polysaccharides in Floral Induction

Nature, 1963
COMPONENT V, which has been previously reported1 to be associated with the vernalization phenomena in rye seedlings, has been further studied. As the electrophoretic mobility of some polysaccharides2 was close to that of component V, polysaccharide content (hexose combined in soluble macromolecular components)3 of extracts of rye seedlings was examined

Extra-DNA During Floral Induction?

1979
Scanning cytophotometric DNA measurements on Feulgenstained nuclei from vegetative and reproductive buds of various age were made in three plants, Sambucus racemosa, Scilladecidua,and Rhoeo discolor. In all three species, a certain portion of the nuclei in reproductive buds exhibited higher 2 C values than the nuclei of vegetative buds.

The vernalization pathway of floral induction and the role of gibberellin

2007
AbstractTemperature, and particularly vernalization, exposure to a prolonged period of cold, is used by plants to regulate the onset of flowering. This is a sensible adaptation of plants in temperate climates to prevent the risk of autumn germination leading to flowering in winter, a time when pollinators are scarce and freezing temperatures may ...
