At first glimpse, there is little family resemblance between astrantias and the typical umbels
, with flat heads composed of myriad flowers.
Note that many members of the umbel
family are herbs.
The yellow flowers, which are borne on umbels
, are also edible, milder and green-tasting.
However, 93.58% of alate aphids were found on the umbels
and 6.42% of alate aphids on the fennel leaves (Fig.
One to two days before nectar collection, plastic bags were placed over four male and four female umbels
per field that were approximately the same size and at the same stage of bloom (Silva and Dean 2000).
Tillett (1967) and Galloway (1975) reported that some Abronia would mature anthocarps for all flowers on an umbel
if even one flower on an umbel
were fertilized, although most anthocarps would be empty.
Seed yield was directly correlated with most of the examined parameters, there being complex relationships involving the combined effect of number of umbels
per plant, average diameter of umbels
and 1000-seed mass.
were compared only to control umbels
on the same plant.
One is a giant...Dill Dukat can grow to 76 cm and will make large umbels
and provide large seedheads for pickles.
On these plants, four umbels
that flowered sequentially were selected, and all others were removed.
One plant family that is particularly important in the garden here are the umbels
. They used to be classified as the family umbelliferae but their clan has now been renamed as apiaceae.
The data were recorded on twelve characters viz., days to 50% flowering, plant height, number of basal leaves, longest basal leaf length, number of fruit bearing branches, umbels
per plant, umbellets per plant, seeds per umbel
, seed yield per plant, 100-seed weight, days to maturity and harvest index.
