Abstract

Indoleacetic acid (IAA), benzyladenine (BA) and (2-chloroethyl)phosphonic acid (ethephon) were applied to pinched and non-pinched ornamental peppers (Capsicum annuum L. cv. Teno) before, after, or at the time of pinching. Ethephon increased the number of lateral branches, but reduced growth, delayed flowering, reduced the number of flowers per branch thus reducing fruit production. Ethephon applied at 300 ppm 2 weeks post-pinching substituted for hand pinching. BA and IAA had no desirable effect on ornamental characteristics of treated plants.

Abstract

In the paper entitled “Effect of Growth Regulators in Branching, Flowering, and Fruit Development of Ornamental Pepper (Capsicum annum L.)” by M. Khademi and M. Khosh-Khui (J. Amer. Soc. Hort. Sci. 102(6).796-798. 1977) the description for Figure 1 should read “C1 is control and C2 to C4 represent 300,600, 900 ppm ethephon, 400, 800, 1200 BA, and 50,100, 150 ppm IAA, respectively.”

Abstract

In the paper, Effect of growth regulators on branching, flowering, and fruit development of ornamental pepper (Capsicum annuum L.), by M. Khademi and M. Khosh-Khui (J. Amer. Soc. Hort. Sci. 102(6):796-798. 1977), the description for Figure 1 should read … C1 is control and C2 to C4 represent 300, 600, 900 ppm ethephon, 400, 800, 1200 ppm BA, and 50, 100, 150 ppm IAA, respectively.

NaCl, KNO3 (0.3, 0.4, 0.5M), KH2P O4 (0.4, 0.5, 0.6M), and PEG 8000 (320 to 370 g/L with the increment of 10g/L) were used for priming Petunia `Ultra White' seeds for three to six days. Seeds were germinated in a growth chamber at 25C. Germination was recorded for seven days and the number of acceptable seedlings (seedlings with open cotyledon and normal root) was counted on the day seven. KH2P O4 at 0.6M was the best salt treatment. Rate of germination was improved by salt priming but the number of acceptable seedlings was lower than the control. Addition of GA (5 ppm) to the salt treatment was not effective. More abnormal seedlings were observed when seeds were primed in aerated salt solutions than when primed in petri dishes. Aerated PEG at 325 g/L for three days and 365 g/L for six days gave the best results. Priming in PEG improved percent of germination, rate of germination, and number of acceptable seedling as compared to control. Primed seeds lost some of the advantages of priming during 24hr air drying (22C), however quality was maintained when dried at 10C. Drying primed seed in 80% R.H. was not effective.
