Title

Effects of Root Cutting in Different Depths on Root System Distribution,Senescence Character and Yield of Peanut

Guo Qin Acta Agriculturae Boreali-Sinica 2015

Other claims from this paper (7)

Intervention effect Moderate root-cutting delayed the decrease in root dry weight at the late stage of peanut.
Intervention effect Moderate root-cutting promoted root growth in deep soil of peanut.
Intervention effect Moderate root-cutting increased the proportion of middle and lower segments of the peanut root system.
Intervention effect Moderate root-cutting reduced root senescence in peanut by delaying the time of maximum root vigor, SOD and POD activity.
Intervention effect Moderate root-cutting reduced malondialdehyde (MDA) content in the root system of each soil layer of peanut.
Intervention effect Moderate root-cutting improved valid pods, pod yield and seed yield of peanut, whereas excessive root-cutting did not.
Recommendation The authors recommend a root-cutting depth of 10 to 15 cm for peanut.

Title

Physiological and Expressional Regulation on Photosynthesis, Starch and Sucrose Metabolism Response to Waterlogging Stress in Peanut

Ruier Zeng; Tingting Chen; Xinyue Wang; et al. Frontiers in Plant Science 2021. doi:10.3389/fpls.2021.601771

Other claims from this paper (14)

Intervention effect Waterlogging increased the main stem height, number of lateral branches and lateral branch length of peanut.
Intervention effect Waterlogging increased the stem diameter of peanut.
Intervention effect Waterlogging increased dry matter accumulation in peanut.
Association Dry matter accumulation under waterlogging was correlated with increases in SPAD and net photosynthetic rate (Pn) of peanut.
Intervention effect Waterlogging increased SPAD and net photosynthetic rate (Pn) in peanut.
Intervention effect Waterlogging upregulated genes related to porphyrin and chlorophyll metabolism and photosynthesis in peanut.
Mechanism The imbalance of the source-sink relationship under waterlogging was the main cause of peanut yield loss.
Intervention effect Waterlogging increased sucrose and soluble sugar contents in peanut.
Intervention effect Waterlogging decreased starch content in peanut.
Intervention effect Waterlogging decreased the activities of sucrose synthetase (SS) and sucrose phosphate synthetase (SPS) in peanut.
Mechanism The decreased sucrose synthetase and SPS activities under waterlogging may be due to changes in the expression of genes related to starch and sucrose metabolism.
Intervention effect Waterlogging decreased the ratio of pod dry weight to total dry weight (PDW/TDW) and yield of peanut.
Association Peanut cultivar HY 39 had a larger decrease in pod dry weight than ZKH 1 under waterlogging.
Mechanism Peanut cultivar HY 39 accumulated more photosynthate in its stem and leaves, which probably prevented effective transport to the pod.
