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 (ER? 1227 and ER? 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 non-grafted
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 ?ER? 1227? grafted onto
?Scarface? rootstock; significantly higher Ca and Mn contents were recorded
when ?ER? 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 ?ER? 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.
