evaluation of quality and quantity of three accessions of grafted and non-grafted of iranian melon

the current experiment was carried out to evaluate qualitative and quantitativeof three melons (cucumis melo gp. ameri) accssions named zardjalal, ananasi and khanoti. the experiment was conducted in a randomized complete block design (rcbd) with 16 treatments and three replications at research field of jahad-e-daneshgahi, campus of agriculture and natural resources, university of tehran. five commercial cucurbit hybrids named ace, shintozwa, shintohongto, zuktozwa and ferro were used as rootstock. non-grafted plants of zardjalal, ananasi and khanoti were used as control. the results show that, rootstock and scion had significant effect on qualityandquantity traits. according to results, maximum numbers of fruits per plant (4.76 no) were related to zardjalal accession on zuktozwa rootstock. the high marketable fruits numbers (3.16 no) and high yield per plant (8.44 kg) belong to zardjalal accession grafted onto shintozwa rootstock to compare other accessions and rootstocks. ananasi accession grafted on zuktozwa rootstock had the highest diameter of the graft, scion diameter and rootstock diameter. zardjalal and ananasi accessions grafted on zuktozwa rootstock had superlative shoot dry matter with 12.89 and 12.72%, respectively. ananasi accession grafted on zuktozwa rootstock had most fruit dry matter with 11.86%. the high cravity (9.5 mm) was seen in zardjalal accession grafted on zuktozwa rootstock. ananasi accession grafted on zuktozwa rootstock had the low fruit length, fruit diameter and flesh thickness. ananasi accession with high brix (11%) was produced sweetest fruits.
