CHLOROPHYL MUTATION-LIKE CHIMERIC CASES INDUCED BY FAST-NEUTRONS IN M1 GENERATION OF A DURUM WHEAT

M. İlhan ÇAĞIRGAN

Abstract

In this study, 3 visible chimeric cases observed in the M1 generation of fast-neutron irradiated durum wheat cultivar, Kunduru-1149, were introduced and possible explanations to their occurence were made in relation to the initial cell numbers, “slicing” effect of fast neutrons and dominant mutations. Considering the chimerism phenomena in M1, dominant mutations should be screened in sectors, i.e. in tillers in cereals, not in the whole M1 plants.

Effects of Different Water Stress Levels on Biomass Yield and Agronomic Traits of Switchgrass (Panicum virgatum L.) Varieties under Semi-Arid Conditio

Erdal GONULAL, Suleyman SOYLU, Mehmet SAHIN

Abstract

A field experiment was conducted in the Wielkopolska region at the Gorzyń Research Station, Poland (52.34°N, 15.54°E) in Central Europe. The study was conducted over a 3-year period (2017, 2018, 2019) as a two-factorial design with four replications in the RCBD. The aim of the research was to determine the effect of the cultivar (‘Bolero’, ‘Tytan’) and the inoculation (Nitragina–seeds inoculation, Nitroflora I–seeds inoculation, Nitroflora II–soil inoculation, HiStick® Lupin–seeds inoculation) on plant development, seeds chemical composition and yielding of narrow-leaved lupin. The weather conditions and experimental factors significantly influenced on productivity of narrow-leaved lupin ‘Tytan’. Drought during the growing season reduced seeds and protein yields. After inoculation of HiStck the seeds yield was significantly greater by 12.4% (p < 0.01) and the protein yield after application of Nitroflora I or HiStick by 13.9% (p < 0.01) and 19.2% (p < 0.01), respectively. Correlation coefficients showed strong relations between number of pods and seeds per plant in both cultivars regardless of the inoculation variant, however the strongest relations in both cultivar were proved on HiStick treatment.
