EFFECTS OF CARAWAY (Carum carvi L.) SEED ON SPROUTING OF POTATO (Solanum tuberosum L.) TUBERS UNDER DIFFERENT TEMPERATURE CONDITIONS

Arif SANLI, Tahsin KARADOAN ,Muhammet TONGUÇ, Hasan BAYDAR

Abstract

Effects of different caraway seed treatments (ground (G) and whole seed (W)) and doses (50 g, 100 g, 150 g) on sprouting, sprout length, the number of sprouts per potato tuber and the weight loss of potato tubers were investigated under two different temperatures (8 oC and 15 oC). At 8 oC, ground seed treatments prevented sprouting until day 105. The most effective treatment was chlorpropham (CIPC) to reduce sprout length. The lowest number of sprouts per tuber was observed for ground seed and CIPC treatments. G100 and G150 were the most effective treatments to prevent weight losses at 8 oC. In general, the effects of CIPC treatment were reduced at 15 oC storage temperature. Ground seed treatments were very effective to prevent sprouting at 15 oC. CIPC was the most effective treatment to limit sprout length at the same temperature. Ground seed treatments were the most effective treatments for reducing number of sprouts on potato tubers and preventing weight losses of tubers.

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.
