Climate change affects seed aging? Initiation mechanism and consequences of loss of forest tree seed viability

Abstract Key message Environmental stress resulting from rapid climate changes leads to the initiation of seed aging process in mitochondria and peroxisomes. Seed storage methods limiting germinability loss are fundamental for forest future. is a natural process. It decreases germination rate, i.e. essential plant’s life cycle. Aging involves progressive accumulation oxidative damage over time. One main plant responses an excessive production reactive oxygen species (ROS), such as O 2 ?• , H • OH. If concentration ROS too high, it causes structure lipid membranes, proteins, carbohydrates, DNA. Climate affect tree reproduction may have long-term consequences form reduced dispersal acquisition new habitats. High temperatures accelerate seeds decrease their viability. There is, therefore, indisputable need store reproductive material maintain continuity regeneration farm forests. The quality subjected correlates negatively with concentration, typically occurs tissues experiencing stress. Therefore, preserve genetic resources, particularly important know sites cells, well prevent rate by developing appropriate methods. organelles responsible intracellular This article aims at verifying determining its future due changes. We review literature on stress, where originates,
