GUZMAN-ANTONIO, Adolfo et al. Effect of the salicylic acid and nutrition on quality of habanero pepper seedlings. Agron. Mesoam [online]. 2012, vol.23, n.2, pp.247-257. ISSN 2215-3608.

The objective of this study was to evaluate the effect of salicylic acid and N P K fertilization on the growth and mineral status of habanero pepper seedlings (Capsicum  chinense  Jacq.).  The  study  was  developed  in Yucatan, Mexico in November 2008 and December  2009. Seedlings  were  exposed  to  four  treatments:  T1)  without salicylic acid and fertilization; T2)  application of 10-8 M salicylic acid; T3) application of 190 mg/l de NPK and T4) application of 10-8 M of salicylic acid + 190 mg/l of NPK. The quality of seedlings was evaluated by measuring growth characteristic of shoot and root. The content of N, P, K, Ca, Mg, Cu, Fe, Zn and Mn was analyzed in whole seedlings. The slenderness and the index of  quality of Dickson were also considered. The results showed significant differences (P≤0.05) on shoot growth. Applications of fertilizer caused increase  on  shoot  dry  weight.  Plant  height,  number  of leaves, stem diameter, and foliar area were not significantly different between T3 and T4. Significant differences  were observed on root dry weight, specific root length, root weight density and root length density. All variables except specific root  length  were  significantly  higher  with  the  fertilizer treatment. The latest had the highest value in the treatment T4. Significant differences (P≤0.05) were observed in tissue mineral  content.  Seedlings  treated  with  T3  showed  the highest content of N, P, Ca, Mg and Mn. The content of K, Zn and Fe was not significantly  different between T3 and T4. In conclusion, the application of salicylic acid favored seedling  growth  but  it  did  not  improve  significantly the quality of habanero pepper seedlings.
