Floral induction in Eucalyptus nitens
Tree Physiology, 1994Eucalyptus nitens (Deane & Maiden) Maiden takes at least five years to initiate flower buds from seed and is an infrequent and light flowerer. Because this behavior constitutes a major impediment to breeding programs, we examined the mechanisms controlling floral induction in E.

Integration of floral inductive signals in Arabidopsis
Nature, 2000Flowering of Arabidopsis is regulated by a daylength-dependent pathway that accelerates flowering in long days and a daylength-independent pathway that ensures flowering in the absence of inductive conditions. These pathways are genetically separable, as there are mutations that delay flowering in long but not short days.

Floral phenology and floral induction in Leptospermum scoparium
New Zealand Journal of Botany, 2018Leptospermum scoparium is a species found throughout New Zealand and southeastern Australia. It typically flowers in the spring and early summer, although occasional flowers can often be seen on pl...

Botanical Gazette, 1955
1. Lincoln, a midseason variety of soybean, became indeterminate in its photoperiodic response with increasing growth and eventually flowered on 18-hour photoperiods. Untreated plants of Ogden, a late variety, did not flower on photoperiods over 141/2 hours long. 2.

Light conditions inside developing buds affect floral induction
Planta, 1982Buds of Pinus sylvestris L. and Picea abies (L.) Karst. were pierced with optical fibres allowing natural light to the vicinity of apical domes. Induction of female strobiles was achieved. Since bud scales absorb more red than far-red light, the treatment may have increased the far-red light absorbing form of phytochrome.

Floral induction in woody angiosperms
New Forests, 1997The 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 ...

Extra-DNA During Floral Induction?
1979Scanning 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.

Polyamines, floral induction and floral development of strawberry (Fragaria ananassa Duch.)
Plant Growth Regulation, 1995In the short-day plant, strawberry (Fragaria ananassa Duch.), polyamines (putrescine, spermidine and spermine), conjugated spermidine (water-insoluble compounds) and bound amines (putrescine, spermidine, phenylethylamine, 3-hydroxy, 4-methoxyphenylethylamine) accumulated in the shoot tips during floral induction and before floral emergence.

The photoperiodic pathway of floral induction
2007AbstractLong day plants and short day plants experience photoperiodic induction of flowering, and so flower in certain daylengths. This chapter considers the photoperiodic regulation of flowering in Arabidopsis, which is a facultative long day plant (that is, one whose flowering is brought forward by long days, rather than one with an absolute ...

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