Results showed that plant height, stem diameter, number of leaves, number of calyces per plant, fresh weight of calyces per plant, dry weight of calyces per plant and calyces yield per ha was significantly affected by different sowing dates as well as planting densities.
For plant densities, the tallest plants (155 cm) with maximum calyces yield per ha (2496 kg) were observed at the highest density of 18 plants m-2, though the per plant stem diameter (2.
Agronomics data were also collected on roselle calyces
(number of calyces

color based on stem color) and leaves production (leaf length and width, economic yield, leaf shape and stem color).
have been used in folk medicines for many years and have been proven to lower blood pressure in patients with hypertension and type II diabetes.
Probably native to tropical Central and West Africa, roselle is mainly cultivated in tropical and subtropical regions of the world (Tindall, 1986; Allel, 2003) for its attractive edible calyces (Purseglove, 1991).
Yield and quality of the calyces and seeds realized on farmers' fields are usually lower than what is being reported under experimental conditions (Babalola et al.
Cuplike calyces containing U-shaped guts and ringed by tentacles are borne on stalks arising from prostrate stolons.
It has been suggested that most or all kamptozoan species are hermaphroditic (Nielsen, 1989), and that colony-level hermaphroditism achieved by gonochoric calyces (mode HhG; [ILLUSTRATION FOR FIGURE 1 OMITTED]) is the rule in the genus Barentsia (Emschermann, 1985, 1994).
Then, in July (Swampy) and August (Irwin) 1993 we harvested five flowers from each plant in a cluster sample (n = 57 at Swampy, n = 30 at Irwin), separated corollae from calyces
, and sealed the corollae in one odor-free film cannister, the calyces
The limitations imposed on their selection response are similar to what might have occurred in the present study had I attempted to simultaneously select for small male calyces
and large female calyces
from the second crop are much smaller and weaker in flavor than the first harvesting.
