The liquid contained within the
bracts was then pipetted into individual plastic pots.
In the axil of the primary
bract develops the secondary axis, bearing two sets of secondary
bracts and terminating in a secondary flower.
"People say, How do you get so many
bracts? and we say, Thats how the plant grows, " said Devin Dotson, the botanic gardens spokesman.
crotalifera have been introduced in the floriculture business mainly differentiated by the size and pigments colouration of
bracts. However, there is limited information about the relationships between
bract colour and pigment composition during the inflorescence development in this ornamental rhizomatic species.
Eryngium alpinum is just as blue but its
bracts are so divided they seem fluffy.
Quantitative characters were: plant height (from the plant basis to top of primary head); plant diameter (one end to the other of the lower leaves); floral stem length (from the plant basis to the primary head insertion); floral stem diameter (10cm below the primary head insertion); number, length and width of the leaves; number of lateral buds formed after harvest; days of implementation to harvest; fresh mass, length and diameter of the primary head; external
bract length; length, width and thickness of the
bracts' edible portion (
bract basis); thickness, fresh mass and diameter of the bottom; number of secondary heads per plant; bottom fresh mass/ primary head fresh mass ratio.
Extracts from
bracts stopped the bacteria responsible for these dental conditions from being able to stick to surfaces and prevented the release of some bacterial toxins.
Bracts are entire, 1-8 mm length, from sessile to amplexicaul.
In cotton (Gossypium hirsutum L.),
bracts, capsule walls, and stems are capable of photosynthetic C[O.sub.2] fixation.
