Senescence of Rice Leaves : VII. PROLINE ACCUMULATION IN SENESCING EXCISED LEAVES.

abstract：:A method is described for the release of large quantities of mesophyll cells from leaves of both cold-hardened and nonhardened winter rye seedlings by a combination of enzymic and physical maceration. Such preparations usually contain a certain percentage of nonviable cells and are thus not suitable for quantitative b...
