Studies on manganese deficiency in citrus. II.

Observations on Boron Deficiency in Citrus

practical and in conformity with the citrus laws and regulations. If you could spend a few months in the Commission office you would be amazed at the number of inquiries received from persons all over the country. Many of these persons request information concerning the citrus industry or its products. One party wants to know something about a new process for extracting citrus juices; another i...

Hydrodynamic studies on the manganese-stabilizing protein of photosystem II.

The solution conformation of the manganese-stabilizing protein of photosystem II was examined by analytical ultracentrifugation. Sedimentation velocity and sedimentation equilibrium studies were performed. These experiments yielded values for of 2.26 S with a diffusion constant, D, of 7.7 x 10(-)7 cm2 s-1. This s value is significantly lower than the apparent s value of 2.6 S previously reporte...

Electrophoretic Studies on Medicinally Important Binary Metal Complexes (system: Copper(ii) / Manganese(ii) / Uranyl(ii) – Sarcosine)

Quantitative indication of the process of forming a complex comes from the evaluation of the stability constants which characterize the equilibria corresponding to the successive addition of ligands. A technique involving the use of paper electrophoresis is described for the study of binary complex system in solution. The first and second stability constants of metal(II) – sarcosine complexes w...

TIlE EFFECTS OF PHOSPHORUS DEFICIENCY ON CITRUS

Manganese Deficiency in Peach Trees:

In previous studies was pointed out that it may be possible to detect subclinical manganese deficiencies in the field before visual symptoms have developed. In this work, by in situ fluorescence measurements, we demonstrate that it is possible to predict, at the beginning of the season, which trees will develop manganese deficiency several months later. Fo/Fm ratio of young manganese deficient ...
