摘要:

1996年测定了9个毛竹种源新竹光合性状。结果表明:所有种源净光合速率在一年中有两个峰值,第一次都在5月,但第二次峰值南带种源早于其它种源;净光合速率年平均值最大的为江苏句容种源,最小的为福建建瓯种源;各种源带净光合速率有随纬度的升高而增大的趋势;单株光合生产率以福建华安种源为最大,最小的为安徽霍山种源;各种源光补偿点的变幅在570~913Lux ,其中中带种源最低,能更有效地利用光能,而北带种源光补偿点明显高于其它种源。

Abstract:

The photosynthetic characters of 9 Phyllostachy heterocycla cv. pubescens provenances were determined in 1996 The result showed that all provenances had 2 peaks of net photosynthetic rate (NPR) in one year.The first peak appeared in May,the second peak of southern provenances was earlier than that of other provenances.The provenance with the largest mean NPR came from Jurong of Jiangsu province,and the one with the lowest mean NPR came from Jian′ou,Fujian province.The NPR in each provenance increased with the increasing of latitude,and the provenances with the highest and the lowest NPR for single bamboo were in Hua′an of Fujian province and in Huoshan of Anhui province respectively.The range of light compensation point (LCP) was 570~913 Lux.The provenances with the lowest LCP which could use the light energy effectively were in the middle area,and LCP of those in the northern area was higher than the others.

Key words: Phyllostachy heterocycla cv. pubescens, Provenance, Photosynthetic character
