High Temperature Inhibits Germination of Jalapeño and Cayenne Pepper

Abstract

<jats:p>The germination of five commercial cultivars of jalapeño and cayenne pepper were tested to determine cultivar response of <jats:italic>Capsicum annuum</jats:italic> L. to supra-optimal temperatures. Two seedlots of `Cayenne, Large Red Thick', `Ole', `Jalapeño M', `Mitla', and `Tam Veracruz' were evaluated on a thermogradient table at temperatures of 20, 25, 30, 35, and 40 °C. Percent germination and time to 50% of final germination (T<jats:sub>50</jats:sub>) were calculated. All cultivars exhibited thermodormancy, but the degree of inhibition varied within temperature and cultivar. No cultivar had &gt;1.0% germination at 40 °C. Generally, the T<jats:sub>50</jats:sub> varied among cultivars, but not among temperatures within a cultivar (T<jats:sub>50</jats:sub> at 40 °C was not measured). Cultivar selection should be considered when growing fall transplants in Florida.</jats:p>

Bromelain crude extract to improve the emergence and growth of pepper seedlings

“…In sweet pepper seeds, the optimum germination temperature is between 20-25°C, and the maximum temperature is 40°C (Carter & Vavrina, 2001). Therefore, exposure to 45°C for three h (Te4), even though this would have constituted phase 1 of germination, may have resulted in the inactivation of enzymes directly involved in seed germination (Dubal et al, 2016).…”

Effect of soaking and adding glutamic acid and phytase enzyme simultaneously on improving GABA content and reducing phytic acid content of germinated Huyet Rong brown rice (Vietnam)

“…According to Cabrera et al ( 2020), the germination of Megathyrsus maximus did not even occur at 10°C and 42°C. Similarly, no cultivar of Jalapeño and Cayenne pepper had more than 1.0% germination at 40°C (Carter and Vavrina, 2001).…”

Efecto del cambio climático sobre la fisiología de las plantas cultivadas: una revisión

“…Vavrina, 2001), causando desplazamientos de cultivos de áreas tropicales a zonas que antes eran frías o de áreas tem-pladas a zonas más frías(Jarvis et al 2008), que terminará por reducir la producción y la calidad de los cultivos (Challinor et al 2007; Tubiello et al 2007b), a la vez, que provoca la proliferación de malas hierbas, artrópodos plaga y enfermedades. Los cambios en el régimen de lluvias aumentan las probabilidades de fracaso de las cosechas a corto plazo y de reducción de la producción a largo plazo(Nelson et al 2009).…”
