Aspects of Nitrogen Metabolism in the Rice Seedling [PDF]

Plant Physiology, 1976
The effects of nitrogen source NO(3) (-) or NH(4) (+) on nitrogen metabolism during the first 2 weeks of germination of the rice seedling (Oryza sativa L., var. IR22) grown in nutrient solution containing 40 mug/ml N were studied. Total, soluble protein, and free amino N levels were higher in the NH(4) (+)-grown seedling, particularly during the 1st ...

Control of Bacterial Seedling Rot and Seedling Blight of Rice by Bacteriophage [PDF]

Plant Disease, 2012
In Japan, rice seed are immersed in pesticide solutions to prevent seedborne diseases that attack greenhouse seedlings. However, disposal of large quantities of waste pesticide solutions after treatment is costly. As an alternative treatment, bacteriophages (phages) that are highly specific to the target bacteria are considered as potential biocontrol

Effect of Anoxia on Carbohydrate Metabolism in Rice Seedlings [PDF]

Plant Physiology, 1995
The metabolism of carbohydrates was investigated in rice (Oryza sativa L.) seedlings grown under anoxia. Two phases can be recognized in the utilization of carbohydrates: during the first days of germination under anoxia, the metabolism of sugars is mainly degradative, whereas after the induction of [alpha]-amylase (EC 3.2.1.1) has taken place, the ...
