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”, “Yécora F-70” and “Yécora Red”. Doses were 0
(control), 50, 100, 150, 200, 250, 300 and 350 mg of PBZ L﹣1 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﹣1 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﹣1 of water. In “Yécora F-70” was 12.2% with 300 mg,
and in “Yécora 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 “Yécora F-70” the
largest decrease (10%) occurred with 150 mg of PBZ, while in “Yécora 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 “Yécora
F-70” and “Yécora 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.
