Photoinhibition, defined as the inhibition of photosynthesis caused by excessive radiance, affects field production to a great extent. This phenomenon is particularly relevant in reforestation practices, when one deals with forests of rapid growth su

In numerous tropical and sub-tropical plant species, such as coffee, exposure to low temperatures can cause extensive tissue damage, the seedlings being particularly sensitive to chilling stress. This condition usually induces changes in the metaboli

Exposure of coffee to low temperatures caused growth inhibition, changes in metabolic rates, and membrane alterations. Root tissue exposed to 10 °C evolved significantly lower rates of metabolic heat compared with controls grown at 25 °C, and the v

Dry matter partitioning was investigated in bulbils propagated from twin-scales and in 1-year-old bulbs of Hippeastrum hybridum (cv. Apple Blossom) under different light regimes. Irrespective of the light regimes imposed there was a steady decrease i

Photosynthetic efficiency is considered one of the traits potentially suitable to differentiate hybrids from their inbred lines. Previous evaluations concerning photosynthetic efficiencies of maize (Zea mays L.) plants in the field have shown inconsi

The capacity of plants to withstand chilling stress has been looked upon as an important adaptive ecophysiological phenomenon, of frequent occurrence in the tropics and sub-tropics. Literature reports have shown that low-above zero temperatures might
