Changes in relative growth rate with plant ontogeny in spring wheat genotypes grown as isolated plants

Autor: Th. Kramer, C.J.T. Spitters

Euphytica 34 (1985)

For a better insight in the effect of wide spacing on the outcome of plant selection in spring wheat, the growth of free-grown individual plants was followed in time for each of 12 cultivars. As time proceeded, the cultivar differences for per-plant

Selection for yield in small plots of spring wheat

Autor: Th. Kramer, C.J.T. Spitters, J.W. van Ooijen

Publikováno v: Euphytica 31 (1982)
Euphytica, 31, 549-564

Four selection experiments were sown: single-row plots with single row-spacing (≃20 cm), single-row plots with double row spacing (≃40 cm), three-row plots and six-row plots both with single row-spacing (≃20 cm). Selection entries were mimiced

Tolerance of spring barley cultivars to leaf rust, Puccinia hordei

Autor: Th. Kramer, M. Van der Ster, B. H. Gildemacher, J. E. Parlevliet

Publikováno v: Euphytica. 29:209-216

Fifteen spring barley cultivars were evaluated in two years for their tolerance to leaf rust, Puccinia hordei. The consistency between the results obtained in the two experiments was rather poor. The most tolerant cultivars produced low seed yields,

Chlorine container experiment

Autor: H. Eggelte, J.P. Brunink, T. Dokter, Th. Kramer

Publikováno v: Journal of Hazardous Materials. 12:11-26

To investigate the effects of the destruction of a chlorine cylinder containing 1000 kg of chlorine, lost by a vessel and residing on the bottom of the sea at a depth of approximately 25 m, some experiments were carried out. The results of these expe

Environmental and genetic variation for protein content in winter wheat (Triticum aestivum L.)

Autor: Th. Kramer

Publikováno v: Euphytica. 28:209-218

There is a considerable amount of variation in the protein content of wheat kernels. This variation may be induced by environmental factors, but can also be attributed to genetic differences. Within a genotype the correlation between grain yield and

Differences between spring wheat cultivars in early growth

Autor: C.J.T. Spitters, Th. Kramer

Publikováno v: Euphytica, 35, 273-292
Euphytica 35 (1986)

Twelve spring wheat cultivars were grown as isolated plants in the field and their pre-anthesis growth was interpreted in terms of plant growth analysis. Relative growth rate (RGR) decreased steadily with time due to a decline of leaf area per unit p
