Suppression of the source activity affects carbon distribution and frost hardiness of vegetating winter wheat plants

Low-temperature effect on enzyme activities involved in sucrose–starch partitioning in salt-stressed and salt-acclimated cotyledons of quinoa (Chenopodium quinoa Willd.) seedlings

“…In this context, photosynthate from cotyledons determines the seedling establishment, and then the growth rate of seedlings depends upon sucrose-starch partitioning [32,42]. Seedling growth is a critical process whose functionality is strongly affected by adverse environmental factors, especially drought, salinity and low temperatures, which affect the source-sink relations (SSR) [15,22,24,32]. Under field conditions stress does not generally come in isolation and many stresses act simultaneously [7,44].…”

“…In photosynthetic tissues sucrose-starch partitioning is the key process to control SSR [22]. Starch production depends upon the concerted activity of several enzymes, but the activity of ADPGPPase is of prime importance in its synthesis [2,3].…”

“…According to several studies seedling adaptation to saline and cold stresses also includes modifications of source-sink relations (SSR) and sucrose-starch partitioning [2,22,33]. Modification of SSR typically shifts the concentration of metabolites, mainly sucrose and starch, in the tissues.…”

Influence of biostimulants on phenolic content in broccoli heads directly after harvest and after storage

“…According to Klimov et al (2008), the increased level of flavonoids at higher temperatures is associated with higher quantities of reactive oxygen species (ROS). However, the opposite trend was observed in our own study.…”

Influence of an O3-atmosphere storage on microbial growth and antioxidant contents of globe artichoke as affected by genotype and harvest time

“…Basically, the low average air temperatures and high amount of rainfall of winter time (January) compared to the early spring ones (March) (Table 4), might be determinant for the favourable TPC. Similarly, TPC is enhanced by low air temperature stress in wheat and buckwheat (Klimov et al, 2008;Suzuki, Honda, & Mukasa, 2005). However, major differences in TPC between harvest times were mainly obtained for the unwashed heads stored under normal atmosphere in cooling chamber (− 34.7%) or at room temperature (− 30.2%).…”
