Tolerance to Low Temperature of Wild, Semi-cultivated, and Cultivated Poinsettia Genotypes [PDF]

HortScience, 2004
Commercial red cultivars (Freedom and Subjibi), semicultivated (Xo-chimilco and Chapingo) and a wild genotype (Puebla) were stored at 2, 7 °C [96% relative humidity (RH)], and 18 °C (50% RH) for 24 and 48 hours. Variables considered were: CO2 and ethylene production, color, chlorophyll content and appearance, evaluating cut leaves and potted plants ...

Primary and secondary abscission in Pisum sativum and Euphorbia pulcherrima –how do they compare and how do they differ?

Frontiers in Plant Science, 2016
Abscission is a highly regulated and coordinated developmental process in plants. It is important to understand the processes leading up to the event, in order to better control abscission in crop plants.
