Sugar Gradients and Translocation of Sucrose in Detached Blades of Sugarcane

Light and Translocation of C14 in Detached Blades of Sugarcane

“…Most confirmin-g l'reviotls tests (9). Basipetal translocation in blades detached in the morning was increased 15.7 times by light.…”

“…With an attaclhe(d leaf the puill fromii belowv is stronig (9), especially the pull fromii the young, growing parts wlhich may be due to kinetini (21). Remiioval of the pull froml the stalk by detachmenit of the blade facilitates the study of the push from the leaf.…”

“…More work is needed on the effect of light upon translocation. However, the fin(ding that light or a light formed factor is essential for the translocation of sugar (9), which is satuirated below the com- Schwabe (17).…”

“…wever, definitely had less total radioactivity. Aprently the loss in total activity, which was assoted with darkening the fed part and attributed to ,piration (9), was prevented by the 6-hour exposure light.…”

“…The varieties of sugarcane used in these experimenits were H 37-1933 and H 50-7209 described previously (9). The plants were grown in full light with adequate nutrition in the field at the Experiment Station.…”
