Abstrct Studies were conducted to observe the effect of different concentrtions of 1-methylcyclopropene (1-MCP) on the post-hrvest life nd qulity of 'Allison' kiwifruit (Actinidi delicios). Fruit were treted with different concentrtions of 1-MCP (0.5 µl l -1, 1.0 µl l -1, or 2.0 µl l -1 ) for 24 h t 20 C nd untreted fruits served s control. After tretment, fruits were trnsferred to mbient temperture storge (22 ± 4 C, 65-70% reltive humidity) for 18 dys, during which observtions on vrious physicl, physiologicl nd biochemicl prmeters were recorded t 3 dys intervls. Our results reveled tht 2.0 µl l -1 ws the most effective tretment to dely softening nd ripening in 'Allison' kiwifruit s such fruit showed the lowest weight loss (9.8 %), hve highest fruit firmness (32.7 N), nd begn to ripen only fter 12 dys in storge, wheres untreted fruit strted ripening on dy-6 of storge. The ctivities of fruit softening enzymes such s polyglcturonse nd lipoxygense were lower, nd totl phenolics contents nd ntioxidnt ctivity were higher in 1-MCP-treted fruits thn in untreted fruits. 1-MCP-treted fruit exhibited lower rtes of respirtion nd ethylene production thn untreted fruits. Similrly, 1-MCPtreted fruit hd high titrtble cidity nd scorbic cid (AA) contents nd lower soluble solids contents thn untreted kiwifruits. Thus, µl l -1 cn be used for the post-hrvest tretment of 'Allison' kiwifruit to enhnce its shelf-life nd mrketbility by pprox. 6 dys. izlrkouk dhohýwv ¼,DVhuhfM;k Msfyf'k;kslk½,d vuks[kk Qy gs] ftldk fnydk jks,nkj o Lokn [kv~vk&ehbk gksrk gsa bl Qy dk mn~xe LFkku rks phu gs ijurq bldh egùkk dks U;wthyS.M us le>k vksj ogk bls ^ckxokuh dk vtwck* dgk x;k gs,o bldk uke ^dhohýwv* ogk ds jk"vªh; i{kh&dhoh* ds dkj.k j[kk x;ka vc bls U;wthyS.M] phu o bvyh es O;kolkf;d Lrj ij mxk;k tkrk gsa Hkkjr es dhohýwv dks lozizfke 1960 es vk;kfrr fd;k x;k] ijurq gky gh ds dqn o"kks± es bldh ckxokuh es dkqh o`f) gqbz gsa gekjs ns'k es dhohýwv dks eq[;r% fgekpy izns'k] mùkjk[k.m] teew o
