panicle

1. a compound raceme, occurring esp in grasses
2. any branched inflorescence

Panicle

 

a compound inflorescence with a main axis that develops lateral branches at various levels. These branches, in turn, produce smaller branches that bear flowers or small inflorescences (for example, the spikelets of grains and the capitula of Compositae). The branches may be tightly pressed to the central axis or may stand away from it. Spreading panicles have horizontal branches. A panicle that is tightly compressed and has short branches— for example, the spike of a grain (timothy, sweet vernal grass and foxtail)—is called a tassel.

panicle

[′pan·ə·kəl]
(botany)
A branched or compound raceme in which the secondary branches are often racemose as well.

The same d, groups of 15 second instar nymphs were transferred to rice panicles (milky stage) using a small brush.
Across all five genotypes, there was a quadratic decrease in the percentage of tagged panicle spikelet sterility when temperatures increased from 9 to 20[degrees]C, demonstrating that the smallest sterility percentages were obtained at the higher temperatures assessed in the experiment (Figure 2).
It is usually due to discoloration of grain, whole panicle, distinct lesions, panicle blight, brown/black spots on grain, discoloration of florets and a number of viral/bacterial/fungal agents that are responsible for developing the disease (LSU Agricultural Center, 1987; Groth et al.
Moreover, Ur1 caused undesirable decrease in kernel weight and spikelet fertility and abnormal panicle morphology, (36) which prompted them to drop their breeding trial.
Studied traits included the number of panicle, panicle weight, seed yield, biological yield, harvest index, thousand seed weight.
Crop and soil parameters: The crop parameters determined were number of tillers and panicles plant-1, plant height, panicle height, fresh and dry weight of straw with and without grain, weight of panicle, grains panicle-1, empty grains panicle-1, weight of grain from each pot, weight of 1000 grains, chlorophyll content of leaf (measured with a SPAD meter), and B concentration in plant straw and grain.
The agronomic assessments were performed when the plants presented the grains in the panicles with milky/farinaceous stage, by means of the measures: plant height; fresh matter yield (ton.

From the samples collected in October two fractions were separated: leaf blades and stems with leaf sheaths (the panicles were ragged by the wind in October).
