Id Subject Object Predicate Lexical cue
T1 0-88 Sentence denotes Evaluation of Polyamine and Proline Levels during Low Temperature Acclimation of Citrus.
T2 89-505 Sentence denotes The polyamines (PA) putrescine (Put), spermidine (Spd), and spermine (Spm) were measured during 3 weeks exposure to cold hardening (15.6 degrees C day and 4.4 degrees C night) and nonhardening (32.2 degrees C day and 21.1 degrees C night) temperature regimes in three citrus cultivars: sour orange (SO) (Citrus aurantium L.), ;valencia' (VAL) (Citrus sinensis L. Osbeck), and rough lemon (RL) (Citrus jambhiri Lush).
T3 506-609 Sentence denotes The changes in PA were compared to the amount of free proline, percent wood kill and percent leaf kill.
T4 610-736 Sentence denotes A 2- to 3-fold increase in Spd concentrations were observed in hardened RL, SO, and VAL leaves compared to nonhardened leaves.
T5 737-968 Sentence denotes Spermidine reached its highest level of approximately 200 nanomoles per gram fresh weight after 1 week of acclimation in both SO and VAL leaves, while RL spermidine content continued to increase up to the third week of acclimation.
T6 969-1035 Sentence denotes Spm levels in acclimated VAL and RL leaves increased 1- to 4-fold.
T7 1036-1094 Sentence denotes However, SO leaves Spm content decreased with acclimation.
T8 1095-1215 Sentence denotes Putrescine levels in SO and VAL increased 20 to 60% during the first 2 weeks of acclimation then declined after 3 weeks.
T9 1216-1275 Sentence denotes RL putrescine content was not affected by cold acclimation.
T10 1276-1391 Sentence denotes The data presented here provided direct relationship between increased Spd concentration and citrus cold hardiness.
T11 1392-1471 Sentence denotes Free proline was 3- to 6-fold higher in acclimated than in nonacclimated trees.
T12 1472-1693 Sentence denotes Results also demonstrate that in acclimated versus nonacclimated citrus trees the absolute amount rather than the ratio of increase in free proline is more important in predicting their ability to survive freezing stress.
