在大田条件下,以两优培九、Y两优1号、玉香油占和黄华占为供试品种,研究了植物生长调节剂GA3和NAA对超级稻成穗率及穗粒结构的影响。结果表明,喷施GA3和NAA后,4个供试品种的成穗率比对照分别提高了15.69%~34.77%和11.35%~17.64%,每穗粒数分别增加了9.02~11.28粒和7.72~11.58粒,产量分别增加了6.58%~14.02%和7.64%~11.44%。可见,喷施GA3和NAA能显著抑制超级稻无效分蘖的发生和生长,增加每穗粒数,减缓后期根系早衰,从而提高产量。

A field experiment was conducted to study the effects of plant growth regulator, GA3 and NAA, on the percent-age of productive tiller and structure of panicle and grain of super rice with Liangyoupeijiu,Y Liangyou No. 1,Yuxiangy-ouzhan and Huanghuazhan as materials. The results showed that the percentage of productive tiller was increased by 15. 69% ~34. 77% and 11. 35% ~17. 64% respectively after spraying of GA3 and NAA, and the grains number per pani-cle was increased by 9. 02~11. 28 and 7. 72~11. 58 and the yield was increased by 6. 58% ~14. 02% and 7. 64% ~11. 44%, respectively. So spraying of GA3 and NAA can improve the yield by controlling the occurrence and growth of un-productive tillers of super rice, increasing the grains number per panicle and delaying the senescence of root system.
