黑皮波羅門參採種觀察試驗

陳榮五 陳水心

摘  要

(一)黑皮波羅門參在本省之採種經三年來之試驗觀察結果,認為在九月至十月播種最理想,由於需經低溫作用才易抽苔之故,太遲播種則抽苔少或不易抽苔。(二)在本省採種目前發現抽苔不整齊,抽苔率及授粉率亦不理想,所以尚待進一步之研究。(三)授粉率在50%而抽苔率達90%以上時每10公畝採種量可達60公斤,抽苔率60%時可達40公斤,抽苔率40%時約25公斤。(四)為提高採種量則必需研究提高抽苔率及授粉率。


 

An experiment on Observation of Seed Multiplication of Black Salsify (Scorzonera Hispanica, L.)

Y. W. Chen, S. S. Chen

Summary

1. Through 3 years of study and observation on seed multiplying for black salsify, it was found that September-October are most suitable planting period for seed producing.

2. According to the black salsify, which needs low temperature to promote blooms, therefore, late planting should be avoided.

3. The quantity of seed production for per ha.  There were (1) 60kg if the rate of blooming above 90% and rate of pollination is 50%.  (2) 40 kg if 60% of blooming rate and 50% of pollination rate.  (3) 25 kg if 40% of blooming rate and 50% of pollination rate.  It was showed in this experiment.

4. There are no problems to produce the seed of black salsify in Taiwan, but how to make it increase the blooming and pollination rates, and obtain the uniformity of blooming period are important and expect to study continuously.
