| 摘 要： | 通过水分仪结合称重法严格控制土壤水分的盆栽试验,研究不同时段干旱胁迫对不同穗型超级稻品种植株形态和干物质积累的影响。结果表明:穗生长发育阶段的干旱胁迫在影响穗器官生长的同时,也抑制剑叶和倒2叶的伸长,导致光合叶面积下降,株高降低。穗分化发育至灌浆结实阶段中度干旱胁迫均导致生物产量和各器官干物重较对照明显降低。不同品种受干旱胁迫影响的程度有所不同,超级稻品种受影响程度比普通杂交稻品种(汕优63)小,大穗型超级稻品种(国稻6号、两优培九)受影响程度低于中穗型超级稻品种(Ⅱ优602、天优998)。干旱胁迫对水稻植株形态和干物质积累的影响与具体品种有关。

| Abstract: | With pot-cultivation and drought stress simulation from the panicle initiation to grain filling stage,the effect of drought stress on plant morphological traits and dry matter accumulation of different panicle type rice varieties(more or middle grains per panicle) was studied.The moisture content in soil was monitored by using a W.E.T Sensor(ML2x type) and an electronic balance.The results showed that a moderate drought stress in different stages had varying degrees of influence on the plant morphological t... |
