Effect of Day and Night Temperatures on the Growth and Development of Common Buckwheat (Fagopyrum esculentum Moench).

Effects of Day Length and Air Temperature on Stem Growth and Flowering in Sesame

“…In sesame, low temperature during the flowering period decreased the rate of increase in the fl owering-node number and the fl owering node number, although it prolonged the flowering period (Table 3). However, in buckwheat, a low temperature does not affect the rate of increase in the flowering-cluster number and slightly reduces the fl owering period resulting in the slight decrease in the fl owering cluster number (Michiyama and Sakurai, 1999). These results demonstrate that the effects of day length and temperature on the flowering of sesame are different from those in buckwheat, although both are short-day plants that exhibit a similar flowering pattern.…”

Increased Night Temperature Negatively Affects Grain Yield, Biomass and Grain Number in Chilean Quinoa

“…Several studies have reported that grain yield is reduced due to higher temperatures at flowering by decreasing grain set in crop species like chickpea (Wang et al, 2006), canola (Morrison and Stewart, 2002), buckwheat (Michiyama and Sakurai, 1999; Michiyama et al, 2001), soybean (Jiang and Egli, 1995), and temperate cereals (Calderini et al, 1999; Wheeler et al, 2000; Ugarte et al, 2007; Lizana and Calderini, 2013; García et al, 2015). Regalona and Accession were highly sensitive to elevated temperatures during flowering, adjusting grain set (from main stem and branch panicles).…”

“…We also found that grain yield was more closely associated with grain number ( R 2 = 0.92; P = 0.001) than grain weight in this experiment, which is consistent with previous studies on quinoa ( Bertero and Ruiz, 2008 ; Gómez et al, 2011 ) and other grain crops ( Peltonen-Sainio et al, 2007 ; Sadras, 2007 ; Gambín and Borrás, 2010 ; Sadras and Slafer, 2012 ). Several studies have reported that grain yield is reduced due to higher temperatures at flowering by decreasing grain set in crop species like chickpea ( Wang et al, 2006 ), canola ( Morrison and Stewart, 2002 ), buckwheat ( Michiyama and Sakurai, 1999 ; Michiyama et al, 2001 ), soybean ( Jiang and Egli, 1995 ), and temperate cereals ( Calderini et al, 1999 ; Wheeler et al, 2000 ; Ugarte et al, 2007 ; Lizana and Calderini, 2013 ; García et al, 2015 ).

Influence of Day Length before and after the Start of Anthesis on the Growth, Flowering and Seed-Setting in Common Buckwheat(Fagopyrum esculentumMoench)

“…However, the variation in the plant development has not been fully examined. Previously, we investigated the differences in growth, flowering process, and seed-setting between summer and autumn eco-type cultivars Michiyama et ai., 1998Michiyama et ai., , 1999, and on the effects of temperature (Michiyama and Sakurai, 1999). There are many studies on the effects of day length, and long day (LD) treatment was found to raise the node position of the first flower node, delay the start of anthesis, prolong the main stem elongation period, retard the growth of pistils, decrease the seed -setting ratio (Tabata et ai., 1931;Xu, 1938;Nagatomo, 1961;Sugawara, 1973).…”
