RG |
Days to root germination |
day |
The number of days from seeding until emergence, with more than half of the seedlings having a first radicle. |
PR |
Primary root length |
cm |
After 8 days of growth under the two treatment conditions, the plants were flattened directly on agar and imaged using a camera. The primary root lengths and lateral root number were determined across the median seedling using ImageJ. |
LR |
Lateral root number |
|
SG |
Days to seed germination |
day |
The number of days from seeding until emergence, with more than half of the seedlings having the first cotyledon. |
EL |
Epicotyl length |
cm |
After 8 days of growth under the two treatment conditions, the plants were flattened directly on agar and imaged using a camera. The epicotyl length and rosette width were determined across the median seedling using ImageJ. |
RW |
Rosette width |
cm |
FW |
Fresh weight of plants |
mg |
All fully-expanded seedlings without lesions were collected from each of 4 plants for each accession and weighed to obtain the fresh weight. The results are the average value across all available replicates. |
K-A |
The amount of potassium absorbed per plant |
mg K/plant |
Elemental analysis was performed with an ICP-MS (Agilent 7500a, USA). All samples were normalized to calculated weights as previously described. The ‘Nutrient absorption(A)’ was expressed as total amount of nutrient per plant; ‘Nutrient concentration (C)’ was calculated by total amount of nutrient per plant /plant fresh weight (FW). The results are the average value across all available replicates. |
K-C |
Potassium concentration per fresh weight |
mg K/g (FW) |
Ca-A |
The amount of calcium absorbed per plant |
mg Ca/plant |
Ca-C |
Calcium concentration per fresh weight |
mg Ca/g (FW) |
Mg-A |
The amount of magnesium absorbed per plant |
mg Mg/plant |
Mg-C |
Magnesium concentration per fresh weight |
mg Mg/g (FW) |
S-A |
The amount of sulfur absorbed per plant |
mg S/plant |
S-C |
Sulfur concentration per fresh weight |
mg S/g (FW) |
Fe-A |
The amount of iron absorbed per plant |
mg Fe/plant |
Fe-C |
Iron concentration per fresh weight |
mg Fe/g (FW) |
Mn-A |
The amount of manganese absorbed per plant |
mg Mn/plant |
Mn-C |
Manganese concentration per fresh weight |
mg Mn/g (FW) |
Na-A |
The amount of sodium absorbed per plant |
mg Na/plant |
Na-C |
Sodium concentration per fresh weight |
mg Na/g (FW) |
