Some of the shifts have been aesthetic: decorator poinsettias in lime green, ivory or burgundy, poinsettias whose petal-like bracts
are flecked, marbled, splashed and otherwise turned into something that will spur your aunt to wonder what they will think of next.

The control treatment and the treatments stored at 12 and 19[degrees]C for two, four, six and eight days did not lead to an alteration in bract
color of the inflorescences, as indicated by the [L.
It's these long nights and short days which induce the coloured bracts
to appear early enough for Christmas.
And there are more genera in the Proteaceae, such as Serruria with its laciniate (jagged) leaves and bluish flowers, Mimetes with a bract
under each flower, and Aulax.
Subsequently, nocturnal closure of the large involucral bract
evolved, apparently to provide a new line of defense against nocturnal florivores [ILLUSTRATION FOR FIGURE 4 OMITTED].
Instead it is achieved by breeding to increase the red pigmentation in the layers of bract
The multicategorical characteristics were as follows: (1) the primary head shape: circular, elliptical, oval, triangular and large transverse elliptical (Figure 1); (2) the head tip shape: acute, rounded, flat, and depressed; (3) the outer bract
tip shape: acute, flat, and emarginated; (4) the external color of the bract
: green, violet-striped green, green-striped violet, mainly violet and totally violet; and (5) the anthocyanic pigmentation of the petiole: absent, weak, moderate, strong, and very strong.
