Type: Report
Identifier: valet-20121106-120953
Description: The experiment reported last month was followed by a time-course experiment in which pairs gf seedlings were analysed 5, 25 or 100 hours after feeding with 5.3 × 10 dpm C-hydroxybutyrate. The distribu… More

Description: Bound to insoluble material, but can be displaced by the formic acid. GLC analysis of purified acid samples moreover showed that the formic extracts contained not only citrate, but all of the acids pr… More

Identifier: No. 57
Description: Results obtained during the last twonionths indicated that light greatly promoted the conversion of radioactive citrate, alanine, aspartate, and acetoacetate to rubber. The same result was given by a … More

Language: EN
Type: Report
Identifier: No. 48
Description: The results of recent feeding experiments were frequently rendered inconclusive by low (50 − 60%) conversions of the rubber to levulinic acid-DNP, and consequent incertainty whether observed yields of… More

Identifier: No. 58
Description: In view of promising results last month, further leaf-disc experiments were carried out to confirm the effect of light on rubber production. Many aspects of plant metabolism are controlled by a phytoc… More

Identifier: No. 59
Description: Leaf-disc experiments have so far been performed in 0.005 M potassium hydrogen phthalate containing 0.001 M CaSO^, the medium used in earlier work on the glycolateserine pathway of isoprone formation … More

Type: Report
Identifier: No. 63
Description: As reported last month, six-hour incubations of leaf discs with C-acetate resulted in only a negligible production of radioactive rubber, in marked contrast to the synthesis achieved in twenty hours u… More

Type: Report
Identifier: No. 61
Description: Effect of light: The inhibitory effect of darkness on in vivo rubber production was conceivably due to rapid inactivation of a particular enzymic function, or, alternatively, a slower decline in activ… More

Language: EN
Type: Report
Identifier: No. 62
Description: The time needed to cut, infiltrate, and count large numbers of leaf discs means that incubations Ik with C-tracers can only be started late in the morning, after which they have mostly been allowed to… More

Language: EN
Type: Report
Identifier: No. 64
Description: In last month.’ s Report it was noted that leaf-discs experiments were no longer giving the relatively high yields 1*1 of C-rubber obtained earlier in the year, and that recent low incorporations migh… More

Language: EN
Type: Report
Identifier: No. 67
Description: Results obtained during January and February made it unlikely that the low yield of C-rubber in recent leaf-disc incubations was due to inadequate lighting, and suggested that a fall in greenhouse tem… More
