Sambucus canadensis(Elderberry), which is cultivated for spicery, edible dye and oil, and so on, is used to investigate the formation of female gametophyte as a part of the embryological studies. The results obtained are as follows: 1. Ovule is anatropous, tenuinucellar, and unitegumic. 2. The embryo sac is of tetrasporic 8-nucleate Adoxa type ; the megaspore mother cell und-ergoes meiosis without the formation of cell wall to form 4 functioning megaspore nuclei, and then all these functioning nuclei undergo just one more division, respectiveiy, to form 8-nucleate embryo sac 3. At the blooming time, the polar nuclei are not fused and tile antipodals also are clearly remained and characterized by all their nuclei maldistrihuting toward the inside embryo sac.

The present study was a part of the project surveying ecological characteristics of soybean collections for breeding materials. Under short day conditions (9 hrs) after flowering, all fifty-five cultivars showed the following results. 1. Seed ripening periods were shortened under short day conditions after flowering, and the accelerating rate was larger in the cultivars from the USA and other country than with domestic or Japanese cultivars. 2. Accelerating in maturity was larger in Kwangdu. Tousan 69, Ao-7445, Pi-31408 and Pi-68552, whereas the flowering nonsensitive varieties under short day conditions, like Haman. Gembokin, Harosoy, Wirth, Wayne and Pi 54613, had the same nonsensitivity in maturity. 3. The short day length during the seed ripening period tended to decrease morphological characteristics such as stem height, stem diameter, number of nodes, number of pods per plant, and number of seeds per plant showing little difference between varieties or their origins. 4. The short day conditions during the ripening period caused a decreas in 100 seed weights showing little variation between origins. The short day leneth also influenced weight of seed per plant showing a difference between origins-that is domestic varieties showed a larger decrease than those from the USA or Japan.
