JOURNAL FREE ACCESSThe experiments were conducted on two varieties of sugar cane, N. Co. 310 and N. Co. 376, in an attempt to examine the effect of maleic hydrazide on the increase in sugar content at Kagoshima, Yakushima and Tokunoshima in two seasons.
The result showed that beneficial effect of the foliar application of 0.3% maleic hydrazide on the improving juice quality was reliable on N. Co. 376, while not apparent on N. Co. 310. It seemed that the chemical was effective to the increase of millable cane weight as well as sugar content.View full abstractDownload PDF (589K) -

JOURNAL FREE ACCESSWe studied the flowering mechanism of cacao in greenhouse and the character of the cacao pollen by germinating the pollen on the agar medium.
And we got some knowledges as follows.
1. Cacao pollens germinate very well on 1.5 percent agar 10 percent sugar medium and the germinating condition is good at 28°C after one night.
2. Pollen germinating percent is higher in A. M. and in P. M. (particulary after 2p. m.) gradually falls.
3. Cacao pollens could not germinate after 24 hours disposing in air.
4. It takes at least 14 hours until the pollen tubes reach at the ovule.
5. Cacao flowers almost fall the next day after flowering, but good lowers stay longer on the tree.View full abstractDownload PDF (8505K) -
