1. The present work was carried out to investigate experimentally if the germination percentage and the pollen tube growth are different among various densities of pollen grains put on sucrose agar media.
2. These pollen grains of the following plant species Camellia sinensis, C. japonica, Iris pseudacorus, Lathyrus odoratus and Oenothera Lamarkiana were used for this purpose.
3. The greater the number of the grouping grains became the more the germination percentage and the tube growth increased. The difference of the tube growth was most conspicuous when a single isolated grain was compared with the two grains grouping set side by side.
4. A group consisting of five or six pollen grains secures the best growth of the pollen tube on agar media, whereas more grouping grains are required to gain the best germination percentage.
5. It was discussed that certain substances might take part in the increment of germination percentage and the acceleration of pollen tube growth.
