“…coreana and P. padus seeds with impermeable hard seed coat were more pronounced at the elevated temperature (Figure 3). However, germination speed can differ according to species, soil structures, sowing methods and especially temperature and soil moisture rations [54]. CO 2 has been shown to stimulate the germination of various seeds at relatively high concentration [55].…”

Effects on seed germination characteristics of 17 tree species were investigated under elevated temperature and CO2. Seeds of 5 needle-leaf and 12 broad-leaf species were germinated under four conditions: 24°C + 400 μmol CO2 mol air–1, 24°C + 750 μmol CO2 mol air–1, 27°C + 400 μmol CO2 mol air–1, and 27°C + 750 μmol CO2 mol air–1. The elevated temperature and CO2 affected germination percent (GP) of 7 tree species seeds.GPs of Pinus densiflora, P. thunbergii, Betula ermanii, and Maackia amurensisseeds were affected by the elevated temperature, while only that of P.jezoensis seed was influenced by the elevated CO2. GPs of Malus baccata and Zelkova serrataseeds were influenced by both the elevated temperature and CO2. In addition, the elevated temperature and CO2also affected mean germination time (MGT) of 12 tree species seeds. Particularly, MGTs of P. thunbergii and Rhododendron tschonoskii seeds were influenced by both factors. In conclusion, elevated temperature and CO2 affected seed germination characteristics, which were reflected by significant differences among tree species. Specifically, these two factors exerted stronger influence on germination pattern such as MGT rather than seed germination percent.

“…Bitki büyüme ve gelişme modellerinin geliştirilmesi ile verim tahminlerinde kullanılacak olan alt modellerin oluşturulması mümkün olabilmektedir. Ülkemizde de, çevre şartlarının, bitkilerin büyüme ve verimleri üzerine olan etkisinin tamamen açıklığa kavuşturulması amacıyla çok sayıda araştırma yürütülmüştür (Uzun, 1996;Uzun ve ark., 2001;Cemek, 2002;Balkaya, 2004;Demirsoy ve ark., 2004;Özkaraman, 2004;Odabaş ve ark., 2007;Kurtar ve Odabaş, 2010;Sarıbaş, 2013;Köse, 2014;Demirsoy ve ark., 2016;Özkaplan, 2018). Bazı sebze türlerinde büyüme, gelişme ve verim tahmin modelleri oluşturulmuş olmasına rağmen, biber bitkisinde bu alanda önemli bir eksiklik belirlenmiştir.…”

Bu çalışma, farklı dönemlerde serada yetiştirilen biber bitkisinin (Capsicum annuum L.) vejetatif büyüme özellikleri üzerine farklı ışık ve sıcaklık şartlarının kantitatif etkilerinin belirlenmesi amacıyla yürütülmüştür. Araştırma, cam ve plastik serada, dört farklı dikim döneminde (Mayıs, Ağustos, Ekim ve Mart) gölgeli ve gölgesiz şartlarda gerçekleştirilmiştir. Gölgeleme materyali olarak %50 ışık geçirgenliği olan plastik ağ örtüden yararlanılmıştır. Çalışmada, Çetinel 150 biber çeşidi kullanılmıştır. Işık ve sıcaklığın, biber bitkisinde vegetatif büyüme parametreleri olan bitki boyu, bitki gövde çapı, yaprak sayısı, toplam bitki vejetatif kuru ağırlığı, yaprak alanı, oransal yaprak ağırlığı, oransal gövde ağırlığı, oransal kök ağırlığı, oransal yaprak alanı, net asimilasyon oranı ve nispi büyüme hızı üzerine olan etkileri ayrıntılı olarak incelenmiştir. İncelenen tüm özelliklerden elde edilen verilerin çoklu regresyon analizleri sonucunda matematiksel modeller elde edilmiş ve oluşturulan modeller 3 boyutlu grafiklere dönüştürülmüştür. Çalışmada, 14-28 °C sıcaklık ve 70-1500 µmol m-2 s-1 ışık şiddeti sınırlarında incelenen büyüme parametrelerindeki önemli değişimler, grafiklerden faydalanılarak açıklanmıştır. Çoklu regresyon analizi sonucunda gerçek ve tahmin edilen büyüme parametreleri arasında istatistiksel olarak önemli düzeyde bir ilişkinin olduğu bulunmuştur. Büyüme parametreleri için üretilen denklemlerin regresyon katsayıları (R 2), 0.72 (oransal gövde ağırlığı) ile 0.94 (yaprak sayısı) arasında değişim göstermiştir. Biber bitkisinde, bitki boyu ve yaprak alanı artan sıcaklık ve azalan ışıkla beraber eğrisel olarak artmıştır. Artan sıcaklık ve artan ışık şartlarında, bitki gövde çapı eğrisel olarak artış göstermiştir. Nispi büyüme hızı (NBH) için optimum sıcaklığın ışık şiddetine bağlı olarak 24-27 °C arasında olduğu saptanmıştır. Bu araştırmadan elde edilen sonuçlar ile özellikle kontrollü seralarda biber üretim planlamasının oluşturulması yönünde ilk adım atılmıştır. Modelling of the quantitative effects of different light and temperature values on growth parameters of pepper grown in greenhouse Anahtar Sözcükler: Biber Büyüme parametreleri Çevre faktörleri Modelleme Sera ABSTRACT This study was carried out to determine the quantitative effects of different light and temperature conditions on vegetative growth characteristics of pepper plant (Capsicum annuum L.) grown in greenhouses in different periods. Plants were grown under shaded and unshaded conditions in four different planting periods (May, August, October and March) in glass and plastic greenhouse. 50% transparent green polyethylene netting cover was used for shading. In the study, Çetinel 150 pepper variety was used. The effects of light and temperature on plant growth parameters (plant height, stem diameter, leaf number, total plant dry weight, leaf area, root weight ratio, stem weight ratio, leaf weight ratio, leaf area ratio, net assimilation rate and relative growth rate) were determined in detail. As a result of multiple regression analy...

“…Craufurd et al (1996) reported reduced germination of 22 cowpea genotypes at temperatures below 15°C, which is similar to results in the present study in which Iron and Clay cowpea did not germinate at temperatures < 15°C. Balkaya (2004) reported predicted optimum temperatures for germination of 23.1 to 25.2°C for two cowpea genotypes across 15 different temperatures ranging from 5 to 40°C. However, our data for Iron and Clay cowpea showed optimum germination temperatures ranging from 15 to 30°C.…”

“…Approximately 93 to 97% of the variation in cowpea [Vigna unguiculata (L.) Walp.] germination and 99% of the variation in soybean (Glycine max) germination can be explained by temperature (Covell et al, 1986;Balkaya, 2004;Odabaş and Mut, 2007). In the suboptimal temperature range, germination rate generally is related linearly to temperature such that temperature and time can be combined into a single thermal time value (Feddes, 1972;Garcia-Huidobro et al, 1982).…”

Temperature, in addition to moisture, oxygen, and light, plays an important role in seed germination. Early seedling emergence and stand establishment can be promoted by germination of seeds under a wide range of temperatures; therefore, it is desirable for commercial legume cultivars to germinate over a range of temperatures. The objective of this growth chamber experiment was to determine the effects of temperature on seed germination of seven annual warm‐season and 11 annual cool‐season legumes. Greatest germination of warm‐season and cool‐season legumes occurred at 25 and 20°C, respectively. Germination of warm‐season legumes tended to be maximized at 25°C, while cool‐season legume germination was greatest from 10 to 25°C. Cultivars ‘Rio Verde’ lablab [Lablab purpureus (L.) Sweet] and ‘Whitetail Thicket’ soybean [Glycine soja Siebold and Zucc. × Glycine max (L.) Merr.] had greater germination than the other entries at 35°C, indicating their potential for use in warmer climates or in delayed planting dates. Additionally, Whitetail Thicket had the greatest germination of summer legume entries at 10°C. The germination of ‘Dixie’ crimson clover (Trifolium incarnatum L.), PI 419238 button medic [Medicago orbicularis (L.) All.], and 600RR and ‘Bulldog 505’ alfalfas (Medicago sativa L.) were less sensitive to temperature than the other cool‐season legume entries. Germination of ‘Devine’ little burr medic (Medicago minima L.), ‘Armadillo’ burr medic (Medicago polymorpha L.), and ‘Apache’ arrowleaf clover (Trifolium vesiculosum Savi) were severely reduced at temperatures above 30°C.
