Growth, yield and maturity of guava, Psidium guajava L. as affected by alar and paclobutrazol application
1990
Braik, N.D.
This study was carried out for two successive seasons, 1987 and 1988. It included a pre-bloom foliar application of N-dimethyl amino succinamic acid (Alar) or [(2RS,3RS)-1-(4-chlorophenyl)-4,4-dimethyl-2-(1,2,4-triazol-1-yl-) pentane-3-ol], (Paclobutrazol) on three-year-old guava seedling trees. In 1987, Alar and Paclobutrazol reduced shoot elongation, and increased fruit weight in trees receiving 1000 or 2000 ppm Alar and those receiving 500 or 1000 ppm Paclobutrazol. In addition, Alar was found to increase fruit flesh firmness. In 1988, shoot growth (length) was less in trees treated with either Alar or Paclobutrazol. Fruit weight was significantly increased only by the 1000 ppm Paclobutrazol treatment. Neither Alar nor Paclobutrazol had any significant effect upon total soluble solids content or titratable acidity of fruits in both seasons. Residual effects of Alar or Paclobutrazol on shoot growth, fruit quality or ripening were not noticed in the year following the season of application
