Add  Electrophysiological phenomena in Hevea brasiliensis.
Authors: Lim, C.M. | Southorn, W.A. | Gomez, J.B. | Esah Yip
Date: 20041202 | 20050202 | | 1969 | | | | | | |
Subject: PRRIM | Plant physiology growth
Type: Article
Identifier: vital1:30005
Description: Electrical potentials can be detected in Hevea brasiliensis as a response lo wounding. The response can be detected only very near the wound and there is no mechanism for distant transmission as obser… More

Add  Latex flow studies III. Electrostatic considerations in the colloidal stability of fresh Hevea latex.
Authors: Southorn, W.A. | Esah Yip
Date: 20030923 | 20050111 | | 1968 | | | | | | |
Subject: PRRIM | Latex physiology
Type: Article
Identifier: vital1:24605
Description: Fresh Hevea latex is a dual colloid system. As a first approximation it consists of negatively charged particles of various types suspended in a serum containing anionic proteins. Included in the nega… More

Add  Latex flow studies V. Rheology of fresh Hevea latex flow in capillaries.
Authors: Southorn, W.A. | Esah Yip
Date: 20030923 | 20050113 | | 1968 | | | | | | |
Subject: PRRIM | Latex physiology
Type: Article
Identifier: vital1:24020
Description: The study concerns the flow of fresh latex through glass capillaries of 20 to 200 u bore and at pressure gradients of up to 2 atm/cm. The apparent viscosity determined from such experiments is constan… More

Add  Latex flow studies VI. Effects of high pressure gradients on flow of fresh Hevea latex in narrow bore capillaries.
Authors: Esah Yip | Southorn, W.A.
Date: 20030923 | 20050113 | | 1968 | | | | | | |
Subject: PRRIM | Latex physiology
Type: Article
Identifier: vital1:23776
Description: Flow of fresh Hevea latex at high pressures through glass capillaries of internal diameter 22 to 80 u was investigated. Flow usually ceased when fresh latex was forced through the capillaries at press… More

Subject: PRRIM | Latex physiology
Type: Article
Identifier: vital1:23934
Description: Latices from trees stimulated with Ethrel (containing 2-ckloroethyl phosphonic acid), acetylene and 2,4,5- T were studied over a period of a year. Rheological measurements showed a change in the surfa… More

Add  Rheology of fresh latex from Hevea collected over successive intervals from tapping.
Authors: Esah Yip | Southorn, W.A.
Date: 20030923 | 20050221 | | 1973 | | | | | | |
Subject: PRRIM | Structure, composition and biochemistry
Type: Article
Identifier: vital1:24501
Description: Early- and late-flow fractions of Hevea brasiliensis latex were exposed to repeated shear. The late-flow fractions showed a response which could only rarely be evoked in the early-flow fractions. The … More
