Other claims from this paper (17)
- Association Se accumulation in alfalfa tissues followed the order Se (VI) > Se (IV) > red Se0, regardless of the applied Se concentration.
- Association Leaf total Se content was higher than stem total Se content in all treatments.
- Association Se accumulation in alfalfa stem and leaf tissues declined gradually between harvests, most clearly for Se (VI) or Se (IV)-treated plants.
- Association Chemically synthesized red Se0 gave results different from the gradual decline seen with the ionic Se forms.
- Intervention effect Application of 10 mg kg-1 Se (VI) gave the highest total Se content in alfalfa stem, 202.5 and 98.0 µg g-1 in the 1st and 2nd harvests.
- Intervention effect Application of 10 mg kg-1 Se (VI) gave the highest total Se content in alfalfa leaf, 643.4 and 284.5 µg g-1 in the 1st and 2nd harvests.
- Association Se (IV)-treated alfalfa showed a tendency similar to the Se (VI) pattern in total Se content.
- Intervention effect Application of red Se0 resulted in lower Se uptake by alfalfa.
- Intervention effect Red Se0 gave less fluctuation in total Se content across the four harvests than the ionic Se forms.
- Observation Selenomethionine (SeMet) and Se (VI) were the major Se forms in the alfalfa samples.
- Observation Neither selenocysteine (SeCys) nor Se (IV) was detected in the alfalfa samples.
- Observation In alfalfa water extracts, Se (VI) was the major Se form.
- Observation SeMet was the predominant Se form in alfalfa enzyme extracts.
- Observation Se (VI) and SeMet contents declined within the harvests in alfalfa, except in stem of plants treated with 50 mg L-1 red Se0.
- Intervention effect Plants treated with 50 mg L-1 red Se0 gave the highest stem or leaf SeMet yield % in all harvests.
- Observation In alfalfa stem of plants treated with 50 mg L-1 red Se0, SeMet yield was 63.6% in the 4th harvest.
- Observation In alfalfa leaf of plants treated with 50 mg L-1 red Se0, SeMet yield was 38.0% in the 4th harvest.
