For the emission gas concentration measurement of sublimable gas phase boron compounds, the optimal collector material applied to the inside stack sampler (the type-1 stack sampler developed in our previous article) was examined. The collection efficiency of alkali impregnated filter paper of calcium carbonate and magnesium hydroxide was investigated by the use of artificial stack. It was revealed that calcium carbonate filter paper have a high collection efficiency and fully applicable to the type-1 stack sampler equally to potassium carbonate filter paper examined in our previous study. However, magnesium hydroxide filter paper is not suitable for the collection agent.

The distribution of chlorophyll intermediates in the rice mutant plants M249 and M134 that accumulate chlorophyllides <I>a</I> and <I>b</I> esterified with incompletely reduced alcohols, such as geranylgeraniol, dihydrogeranylgeraniol and tetrahydrogeranylgeraniol, were determined in five chlorophyll-protein complexes and free pigment resolved by non-denaturing polyacrylamide gel electrophoresis. The <I>a</I>/<I>b</I> ratios of chlorophyll intermediates in mutant thylakoids were similar regardless of reduction state of chlorophyll moieties. In light harvesting complexes and photosystem II core proteins of the rice mutants, the proportions of the intermediates in total chlorophylls were nearly constant. However, the proportions of chlorophyll-geranylgeraniol in P700-chlorophyll <I>a</I>-protein complexes of mutants were clearly lower than those in photosystem II core and antenna complexes. These results suggest that chlorophylls with less-reduced side chain are unlikely to be incorporated into photosystem I core protein complex, and that other photosynthetic protein complexes, such as P680-chlorophyll <I>a</I>-protein complex and light harvesting complexes, are independent of reduction state of the side chain.
