Morphology and Physiology of Germinating Barley at Each Developmental Stage. Figure 1A. Morphology and time points of germinating barley at each developmental stageThe morphology of germinating grains and seedlings at each developmental stage and the typical time taken for dry mature grains to reach each stage are shown. The relative times in reference to the time taken to reach S3 stage are indicated in the parenthesis. S3: Coleorhiza emerging from grains at 18 hours of germination. S4: the rootlet length is half that of its grain at 33 hours of germination. S5: the shoot is 3 times as long as its grain at 71 hours of germination. Figure 1B. Water content of germinating barley at each developmental stageThe fresh and dried weights of 10 germinating grains or seedlings at each developmental stages defined as in the Figure 1A were measured. The water content in germinating barley at each stage is indicated as Y axis as a percentage of the dry weight. The representative time point of germination at each stage is indicated as X axis. Standard derivations of the three replications are indicated as error bars. Stages are marked. Figure 1C. Alpha-amylase activity in germinating barley at each developmental stageThe X axis indicates the development stages. The average amount of maltose in umole produced per gram of fresh examined tissues (U/gfw) and the standard derivation of three replications are indicated on Y axis. Figure 1D. Desiccation resistance of germinating barley at each developmental stage The germinating barley at each developmental stage were dehydrated, and then re-germinated. The percentage of the dehydrated germinating barley that could revive to their growth was defined as survival rate and indicated as Y axis to measure desiccation resistance of the germinating barley. The X axis indicates developmental stages. Standard derivations of the three replications are indicated as error bars.
