A field experiment was conducted to investigate the rootstock effects on the fruit and
seed yield and leaf nutrient contents of pepper, four pepper inbred lines (ERÜ 1227 and
ERÜ 462: Long fruited green pepper type; 21 H-1-2 and 33 H-3-1: Bell shaped pepper
type) were grafted onto two pepper rootstock genotypes (46 KB F1 and Scarface F1).
The non-grafted scion genotypes were used as control plants. Between grafted and nongrafted plants significant (p<0.001) differences were found in fruit yield, dry matter,
diameter, length and fruit number, seed yield, thousand seed weight and leaf P, K, Ca,
Mg, Mn and Zn contents. Among the graft combinations, significantly higher fruit
yield, dry matter, length of long fruited green pepper genotypes, leaf K content was
observed when ‘ERÜ 1227’ grafted onto ‘Scarface’ rootstock; significantly higher Ca
and Mn contents were recorded when ‘ERÜ 462’ grafted onto ‘Scarface’ rootstocks.
Whereas, significantly highest fruit number and diameter of long fruited green pepper
genotypes was recorded at the non-grafted plants of ‘ERÜ 1227’. Overall, the pepper
rootstock genotype ‘Scarface’ showed a better performance for fruit yield, dry matter,
length of long fruited green pepper genotypes, fruit diameter of bell shaped pepper
genotypes, K, Ca, Mg and Mn contents in leaf tissue, thousand seed weight in different
graft combinations as compared to non-grafted pepper plants. All these suggest that the
powerful rootstocks, which might be characterized by an efficient nutrient uptake, play
a major role in improvement of plant growth performance, fruit, and seed yield.
