%X To know the response of the wheat in the greenness, plant height and
grain with yellow berry, paclobutrazol (PBZ) was applied to the foliage of the
cultivars ¡°Cachanilla F-2000¡±, ¡°Y¨¦cora F-70¡± and ¡°Y¨¦cora Red¡±. Doses were 0
(control), 50, 100, 150, 200, 250, 300 and 350 mg of PBZ L<sup>©�</sup><sup>1</sup> of water, which were applied only once with a hand pump. The
experimental design was a randomized complete block with four replications;
experimental units of four rows of 20 m long, which were fertilized with 364 kg¡¤N¡¤ha<sup>©�</sup><sup>1</sup> more 56 kg of P, were applied in pre-seeding. In ¡°Cachanilla
F-2000¡± greenness, the maximum increase (7.2%) was achieved with 100 mg of PBZ
L<sup>©�</sup><sup>1</sup> of water. In ¡°Y¨¦cora F-70¡± was 12.2% with 300 mg,
and in ¡°Y¨¦cora Red¡± was 19.1% with 50 mg of PBZ. In ¡°Cachanilla F-2000¡± height
decreased 6.0%, 6.3%, 6.3%, 9.4%, 10.7%, 10.9% and 13.0% with 50, 100, 150,
200, 250, 300 or 350 mg of PBZ, compared with the control. In ¡°Y¨¦cora F-70¡± the
largest decrease (10%) occurred with 150 mg of PBZ, while in ¡°Y¨¦cora Red¡±
height decreases ranged from 7.9% - 17.0% with doses of 50 - 350 mg. The yellow
berry decreased from 48.5% - 74.4% in ¡°Cachanilla F-2000¡±, and to zero in ¡°Y¨¦cora
F-70¡± and ¡°Y¨¦cora Red¡±. These results indicate that PBZ can be used to increase
greenness and photosynthesis to improve the quality of the grain of flour and
durum wheat.
