Cytokinin and growth of excised roots of Bryophyllum calycinum.
Excised roots of Bryophyllum calycinum require for growth both auxin and cytokinin. This is demonstrated by the poor growth of 2-mm root tips in a basal medium of mineral salts, sucrose, and vitamins supplemented with either an auxin or a cytokinin, and much better growth when the basal medium is supplemented with both auxin and cytokinin. However, both substances are synthesized by the root, a...
متن کاملChanges in the Acidity of Bryophyllum Calycinum
In studies on the hydrogen ion concentration gradient and total acidity in plants it was noticed that these varied greatly in Bryophyllure calycinum with the light conditions of the day; on a cloudy day the H ion concentration and total acidity were very high, while on a bright sunny day they were 10w. ~ From this it was inferred that there might be diurnal changes in these concentrations. Refe...
متن کاملPhytochemical and acute toxicity study on Bryophyllum calycinum Salisb.
The plant Bryophyllum calycinum Salisb. (Crassulaceae ) is a shrub mainly found in the tropical parts of Bengal and in southern Africa and American continents. It is locally known as ìPatharkuchiì and for long has been used in Ayurvedic medicine. As per traditional use, the leaves and leaf juice are used as antiviral, antipyretic, antimicrobial, anti-inflammatory, antitumorous, hypocholesterole...
متن کاملPreparation of potassium dihydrogen Ls(+)-isocitrate from Bryophyllum calycinum leaves.
Although several procedures have been described for the synthesis of isocitric acid, (l-4) the optically inactive product obtained may be contaminated with the diastereomeric alloisocitric acid and, if pure, contains at most only 50 per cent of the isomer of interest in biochemistry. Pucher, Abrahams, and Vickery (5) attempted to meet the need for this substance by devising a method for the iso...
متن کاملThe Organic Acids of the Leaves of Bryophyllum Calycinum
It has been known since the work of Mayer (1) in 1875 that the thick succulent leaves of many plants of the family Crassulaceae become enriched in titratable organic acids during the night and diminish in acid content when the leaves are illuminated. An analogous diurnal variation in acidity has been observed in a number of other succulents, and occasionally in species of different growth habit...
