摘要
为研究不同甘蔗基因型在低氮胁迫下的主要农艺性状、产量和品质性状等方面的表现,以‘新台糖22号’为对照,对04系列6个甘蔗新品系进行新植品比试验。试验结果表明:04/1028、04/1531、04/522、04/539、04/2299、04/109在出苗率、茎径、有效茎、产蔗量及含糖量方面均明显超过CK。其中04/539耐低氮胁迫能力较强,产蔗量及含糖量分别为104.81t/hm2、15.04t/hm2,比CK增加17.46%和15.04%。低氮胁迫对各参试甘蔗品系的分蘖率、蔗茎伸长有明显的不利影响。试验结果可为进一步筛选固氮甘蔗优良品种提供参考。
The aim was to know the manifestations of different sugarcane genotypes in low nitrogen stress.ROC 22 was used as control in the comparative planting experiment,and six Guitang strains from seeding in2004 were studied.The results indicated that germination rate,stalk diameter,millable stalks,the cane yieldand sucrose content of 04/1028,04/1531,04/522,04/539,04/2299 and 04/109 were higher than those of CK.The ability of Guitang 04/539 in low nitrogen stress was strongest.Its cane yield and sucrose contents were104.81 t/hm2 and 15.04 t/hm2,which increased 17.46%and 15.04%,respectively,compared with CK.The tillering rate and internode elongation of the sugarcane strains were influenced badly by low nitrogen stress.The result could be given reference for further nitrogen efficiency sugarcane breeding.
