DIMENSION, GEOMETRIC, AGRICULTURAL AND QUALITY CHARACTERISTICS OF SAFFLOWER SEEDS

Rahim ADA

Abstract

This research was carried out in the research field of Agricultural Faculty, Selcuk University, Konya, Turkey. Field experiments were carried out in two growing seasons (2011 and 2012) according to “Randomized Complete Block Design” with three replications. In the study, a total of 13 promised safflower (Carthamus tinctorius L.) lines (A13, A29, C12, E12, F4, F5, F6, G16, H3, J19, Y1-8-14-1, AOL-2(2), DP 1.5.8-1) and 5 cultivars (Black Sun1, KS 06 and Oleic Leed, Dinçer, Remzibey) were used as material. Oil content of the safflower genotypes were ranged in between 24.05-33.18%. The highest protein content value was obtained from J19 line (21.72%) while the lowest was found on the Turkish cultivar of Remzibey (16.03%). Negative correlations were found for oil content and hull thickness (r=-0.3152**), hull ratio (r=-0.7122**) and pappus ratio (r=-0.3408**). Protein content was found as significantly and negative correlated with some characters, similar to the seed widness (r = -0.2546**), seed thickness (r=-0.1918*), geometric diameter (r=-0.3194**), seed surface area (r=-0.3119**), pappus ratio (r=-0.3114**) and 100-seed weight (r=-0.2597), respectively. According to the results, increasing the dimension and geometrical values cause to a decrease in the oil and protein content of safflower seeds. Quality components (oil and protein content) showed negative correlations with both of pappus rate and hull features.

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

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.
