Abstract
1. The relation-ship between the light factors and the polyploidy in 8 Rubus species has been researched by the writer in their growing places in Ehime prefecture. The species of Rubus which were used in this research are as follows: R. parvifolius, R. Wrightii, R. palmatoides, R. hirsutus, R. phaenicolasius, R. Sieboldii, R. pectinellus and R. Buergeri.2. The average value of the relative intensity of light at their growing places is as follows: 2X=72/100, 4X=54/100 6X=32/100 and 8X=34/100. Namely, the relative intensity of light of polyploid plants is larger than that of the diploid plants and the relative intensity of light decreases according to the duplication of the chromosome numbers.3. The polyploid plants of Rubus seem to have got anew the special quality to grow well in the shade. The diploid plants are the deciduous, while the polyploid plants pass the winter ever green. The polyploid plants which pass the winter ever green grow well the shade because the shade controls the transpiration of leaves and does not break the balance between the transpiration of leaves and the absorption of roots.
