主 题:A PROCESS OF OBTAINING POLLEN PLANTS OF HEVEA BRASILIENSIS MUELL ARG
摘 要:In February—March 1977, five pollen plants were produced by anther culture of Hevea brasiliensis Muell.-Arg. All of them had main roots, cyclic lateral roots, stems, cotyledons, first pairs of leaves, and terminal buds. The whole process of development of pollen grains into embryoids was observed microscopically. The observations of chromosome constitution of fifteen embryoids with a diameter of 2—3 mm revealed that all of them were haploid (with a chromosome number of 18). In the root-tips of the plantlets many aneuploid cells were scored and a small portion of cells remaincd to be haploid, but no diploid cell was observed. Thus, we can be sure that the plants obtained from anther culture were originated from pollen grains.
