raceme

an inflorescence in which the main stalk bears the flowers on stalks (pedicels), producing a conical form. An example is the foxglove, in which there is usually no terminal flower.

Although larger genets produced more racemes and flowers than those smaller, greater pod inflation and higher seed yield were occasional events mainly associated with the latter variables.
Each raceme was divided into three parts named early part, intermediate part and late part.
Initial observations in late afternoon of moths at butterfly bush flowers indicated plume-tracking behavior (zigzagging upwind flights) at distances up to 2 M downwind of flower racemes, but these moths were not identified.
alba, larger plants with more racemes flowered earlier and tended to yield more mature seeds, although the difference in yield was never significant (Petersen et al.
In such cases, when the florescence consists of solitary flowers arranged along an axis, the FU is either a spike (or spiciform inflorescence) or a raceme.
Counts of seeds matured and weevils were taken from five ripened pods sampled from each raceme of a plant.
of the primary shBrs determines a raceme of spikelets or a spike of spikelets depending on whether the internode has developed or not, respectively (Camara Hernandez & Rua, 1992; Vegetti & Anton, 2000); (3) different types of panicles: (a) with spicate or racemose branches (Vegetti & Anton, 2000); (b) with alternate, subopposite or pseudoverticillate branches (Vegetti & Anton, 2000; Reinheimer & Vegetti, 2008); (c) with branches along an axis with conspicuous intenodes, or with these internodes and two distal ones conjugated or with only two conjugated primary branches (Paspalum, Rua & Weberling, 1998; Souza-Chies et al.
The Cu and Mn content concentration in plant parts was found to be in following order: roots > leaves = racemes > stems.
During August and September as plants began to senesce, five sealed pods were collected from each raceme and sampled for counts of matured seeds and weevils.
This pattern of activity produces a raceme, which can be modified as a spike or an umbel.
Elongation of the raceme takes place late in ontogeny, long after the flowers are formed by the inflorescence apex.
We are characterizing a suite of Pisum sativum mutants that alter inflorescence architecture to construct a model for the genetic regulation of inflorescence development in a plant with a compound raceme.
