结果表明:(1)两季平均,FACE处理使汕优63移栽-分蘖中期、分蘖中期-拔节期、拔节-抽穗期和抽穗-成熟期干物质生产量分别比对照增加了39%、20%、32%和41%,结果使成熟期生物产量显著增加(+33%);(2)与干物质生产量相比,汕优63平均叶面积指数(LAI)和净同化率(NAR)对CO2的响应有相似的季节性变化趋势,但LAI的响应值明显大于NAR;(3)FACE处理使汕优63不同生育时期叶片和稻穗占地上部干重的比例下降,而使茎鞘占地上部干重的比例明显增加;(4)三系杂交籼稻汕优63成熟期生物产量以及不同生育阶段平均LAI、NAR和干物质生产量对FACE的响应与粳稻品种存在明显差异,而干物质分配差异较小。
The results showed as follows, long time sub-high temperature of daytime decreased the relative growth ratio and net assimilation ratio, and advanced the phenophase of plant , and a long period time of sub-high temperature treatments even made the plants decline earlier.
结果表明,长期35℃昼间亚高温处理,番茄植株相对生长速率降低、净同化率减小,同时番茄生育物候期提前,缩短了植株生育期,提早果实发育,但果实坐果率下降、平均单果重变小,导致果实产量降低;亚高温条件下番茄果实品质下降,处理时期越早,品质下降越明显。
