JOURNAL FREE ACCESS1. Since 1941, we have demonstrated the experiments of Photoperiodism, in several textile crops, departing into same classes by the length of the natural day light and artificial electric light. The cost of this research has been defrayed from the scientific research expenditure of the Department of Education.
2. Kenaf, Ambari or Bombay hemp (Hibiscus Cannabinus. L) is a short day plant, but the ifluences of the length of day are variable by the varieties.
3. The original colours in the stem and the leaf of the Kenaf under natural conditions, are greatly influenced, by the length of the day. The shapes of the leafblades, especially either pinnately parted or lobed, also, are almost the same. Namely, the letters are greatly affected by the length of day.
These facts are not only interesting of the investigation on crop science, but also remarkable problems of the research on plant breeding, genetics and ecology.
4, The influences on Jute (Corohorus Capsularis, L) are greatly variable by the varieties. But the cultivable regions are suitable, generally in low latitudes. In high latitudes, they varieties, are almost impossible so much as to get seed ripening.
5. Chinese Jute or Indian mallow (Abutilon avicennae, G) is a short day plant, but blossoms even under long day. The cultivable regions of this crop are pretty expansive, in the standpoint of the length of day. Low temperature, however, is bad on this crop. Simplicities of cultivation, retting and fiber cleaning process are the particularities of this crop.
6. Ramie or China grass (Boehmeria nevea H. et A.) makes the inversion of sex, by the length of light exposure. And, the stem length of this crop turner to lower by short day exposure, as many other crops.View full abstractDownload PDF (1012K) -
