Model for Short Term Movements in Stapelia variegata Linn.
نویسندگان
چکیده
Recently it was demonstrated that holographic interferometry could be used to quantify minute displacements of a mature Stapelia variegata Linn. The previously unobtainable measurements revealed that the short term response of the stapelia was regular enough so that the dynamics could be evaluated through the use of a highly damped mass, spring, dashpot model. Such a model is derived explicitly and the relationship between movements of the entire plant and the dynamics of individual cells or groups of cells is shown.

Holographic interferometric measurement of motions in mature plants.
Holographic interferometry has been used to plot graphs of the phototropic and geotropic bending undergone by a mature Stapelia variegata Linn over a 5-minute period. The holographic interferometric technique is shown to have the advantage of measuring displacements at least as small as 0.16 micrometers which permits observation of extremely slow plant motions over time periods of a few minutes...

Extracts of leaves and roots of Ocimum sanctum Linn. and leaves of Bauhinia variegata Linn. were used to evaluate their antimalarial effect against Plasmodium berghei in vivo in a typical 4 day test. Water and ether soluble extracts were administered orally to experimental mice along with placebo controls. On day 4 parasitaemia in control group of mice was 25.20% ± 9.44% while in mice treated w...
متن کاملIdentification, isolation and some properties of lectin from the seeds of Indian coral tree [Erythrina variegata (Linn.) var. orientalis (Linn.) Merrill].
A D-galactose-binding lectin agglutinating human erythrocytes has been purified from the seeds of the Indian coral tree (Erythrina variegata (Linn.) var. orientalis (Linn.) Merrill] by affinity chromatography on acid-treated Sepharose-6B gel. It has a higher reactivity for O-group erythrocytes. The lectin is a glycoprotein having a leucoagglutinating property.
