Coleoptile and Mesocotyl Lengths in Semidwarf Rice Seedlings1
Crop Science, 1982Drill‐seeded semidwarf rice (Oryza sativa L.) emerges slower and with less consistency than taller plant types. To determine if short mesocotyls or coleoptiles cause emergence problems, three semidwarf cultivars (‘Bellemont’, ‘M‐101’ and ‘IR‐24’), two taller cultivars (‘Labelle’ and ‘Starbonnet’), and strawhulled red rice were planted at 1, 2.5, 4, 6 ...

Coleoptile length is often associated with fall stand establishment in winter wheat (Triticum aestivum L.). While coleoptile length evaluation and improvement is a common objective of wheat breeding programs, little information is presently available to guide effective evaluation efforts.

Inheritance of Coleoptile Length and Culm Length in Crosses Involving Olesen's Dwarf Spring Wheat1
Crop Science, 1973Coleoptile length and culm length inheritance were studied in F1 and F3 populations from spring wheat (Triticum aestivum L.) crosses involving ‘Olesen's Dwarf’ and five tall cultivars with relatively long coleoptiles. In F2 populations studied both characters were quantitatively inherited.

Effect of selection for coleoptile length in rye, Secale cereale L.
Euphytica, 1974Two hundred and forty seedlings from each of three diverse populations were measured for coleoptile length. Significant differences between populations were found for mean coleoptile length. Considerable variability was obtained within each population with coefficient of variation values ranging from 32 to 42%. Forty seedlings from each population were

Response to selection, combining ability and heritability of coleoptile length in winter wheat
Euphytica, 2008Selection of winter wheat cultivars with long coleoptiles is an important component of improving emergence, weed suppression and grain yield in low rainfall regions of the world. Seven winter wheat cultivars were hybridized in a Griffing’s half-diallel mating design, method 2 (reciprocals excluded, parents included), model 1 (fixed), and the progeny ...

The inheritance of crown depth was determined by measurement of subcrown‐internode length in a winter wheat (Triticum aestivum L.) cross between the semidwarf selection C.I. 13253 (‘Norin lO’/Brevor 14) and the standard height cultivar ‘Brevor.’ Cultivars and selections that form deep crowns have been reported to show less winter injury.

Seedling Root and Coleoptile Length as Selection Criteria for Field Emergence in Pearl Millet
Journal of Sustainable Agriculture, 2001ABSTRACT Pearl millet (Pennisetum glaucum [L.] R. Br.) production in semi-arid regions is limited by poor seedling emergence that results in poor stand establishment and, low yield. Six pearl millet populations were created by divergent selection within the Tift #2 S-1 (TIFT2) pearl millet population for seedling root length in sand in the greenhouse ...

The dependence of elongation on the osmotic potential of the medium was investigated, using coleoptile segments (CS) of Triticim aestivum L. (cv. Hartri) and an optoelectronic device. The study aimed at separating the osmoelastic response from the irreversible growth response when an osmoticum (mannitol) was added, and to compare both processes in ...
