能源油料植物续随子的综合性状分析

Analysis on Comprehensive Characters of Euphorbia lathyris,an Oil Plant for Energy

以NX-08／1为对照，对收集引进的4个续随子品种（材料）的生物学、植株生长量、开花结实物候期、籽粒产量及种子含油率进行观测。结果表明：4个续随子品种（材料）平均株高分别达到114．2～127．6cm，从高到矮依次为GF-08／2〉NX-08／7〉NX-08／3〉NX-08／2〉NX-08／1（CK）；产量达到111．79～143．67kg／667m^2，NX-08／2〉NX-08／3〉GF-08／2〉NX-1（CK）〉NX-08／7；含油率达到40．6％～45．4％，从高到低依次为NX-1（CK）〉NX-08／3〉GF-08／2〉NX～08／2〉NX-08／7。从适应性看，4个续随子品种（材料）都可在贵州喀斯特山区进行选择推广。

The biology, plant increment, phenophase of flowering and fruit-bearing, seed yield and seed oil content of four introduced Euphorbia lathyris varieties and NX-1 （CK） were observed. The results showed that the average plant height of four introduced Euphorbia lathyris varieties varied from 114.2 to 127.6 cm and the plant height of GF-08/2 was the most height and NX-1 （CK） was the shortest among five tested varieties, the yield of 5 tested varieties varied from 111.79 to 143.67 kg/667m^2 and its yield order was NX-08/2 〉 NX-08/3） GF-08/2） NX-1 （CK）） NX-08/7, and the seed oil content of 5 tested varieties varied from 40. 6% to 45.4% and its order was NX-1 （CK） 〉NX-08/3〉GF-08/2〉NX-08/ 2〉NX-08/7. Four introduced varieties with a good adaptability can be popularized in mountainous areas of Guizhou province.
