Abstract
Objective] To study effect of the indolebutyric acid ABA on growth of wheat seedling stage.[Method]Effect of spraying the In-dolebutyric acid S-ABA (1% wettable powder) at the dilution of 5 000, 4 000, 3 000 and the 2 000 on the tillering number,the root length and number, the fresh weight were studied.[Result]The result showed that the dilution of 5 000,4 000,3 000 and 2 000 was that Plant height decreased by 3.31%,3.39%,10.74% and 15.29%, the tillering increased by 2.80%,6.54%,7.48% and 8.41%, the root length in-creased by 4.41%,11.51%,17.94 and 19.28%, the root increased by 9.21%, 17.23%,24.91% and 26.08%, the fresh weight of under-ground increased by 6.38%,9.00%,11.00%and 11.27%, the fresh weight on the ground creased by 3.45%,6.16%,7.38%and 7.94%. [Conclusion]Spraying indolebutyric acid ABA could deducethe wheat height, promotethe new root growth, increased the tillering and the fresh weight.关键词
