Effect of Pre-Grafting Incubation and Grafted Cuttings Positionon Grape Grafting Success

Abstract

HIS EXPREMENTS was carried out during two successive ……..seasons 2015 and 2016 at the nursery of pomology department, Faculty of Agriculture, Cairo university, Egypt. The study was aimed to investigate the effect of two fators namely i.e, pre-grafting incubation and grafting materials position during callusing on grafting success of flame seedless grapes onto Salt Creek rootstock. Callusing was carried out in three positions i.e, horizontal, upright and upright down either with or without pre-grafting incubation. The results showed that either pre-grafting incubation or callusing at uprightposition increased significantly callus percent and degree, sucker number, rooting rate, bud break percent during callusing period and grafting success percent. The interaction, betweentreatments revealed thatcallusing at uprightpositionaccompanied with pregrafting incubation gave the best results in this respect. It can be concluded that callusing at uprightposition either with or without pregrafting incubation increased grafting success significantly compared to callusing at horizontal or upright down position.Chemically, higher grafting success is accompanied with lower phenols, reducing sugars and total indoles. It may be concluded that there is no antagonistic effect between root and callusformation in grafted cuttings. Also, upright position for incubation the grafted cuttings are better than pregrafted incubation in increasing grape grafted cuttings.

Callusing soil of grafted grape cuttings as a positive feature for climate change

“…The callus degree in the grafting zone was assessed based on visible observations: 4 = 76-100% callus, 3 = 51-75% callus, 2 = 26-50 callus, 1 = 1-25% callus and 0 = no callus Callusing soil of grafted grape cuttings as a positive feature for climate change (KOSE;GULERYUZ, 2006;PAUNOVIC et al, 2011). The grafts callusing% was calculated from the following equation (total number of callused grafted at grafting zone / total number of grafts) *100) according to Rashedy, (2016). The grafted rooted percent was calculated from the number of rooted grafts (rootstock) divided by the total number of grafts (KAMILOGLU; TANGOLAR 1997).…”

“…However, graft zone formation is affected by several factors such as plant genetics, propagation techniques, growth regulators application, the scion -rootstock combinations, pest and disease control (HARTMANN et al, 2002;YOUQUN, 2011;FAYEK et al, 2016;FAYEK et al, 2022). Also, environmental conditions during grafting, rootstock activity and the biochemical and physiological status of grafted materials affected grafting success (FAYEK et al, 2016;RASHEDY, 2016).…”

“…Callusing date, which depends on the biochemical and physiological status of grafts partners (rootstock and scion) as well as the callusing method which controls in the environment (temperature and humidity) are the most critical factors in grape grafted cuttings success that needs to both root formation and grafting union formation at the same time (RASHEDY, 2016). In addition, the incubation of grafted partners two weeks before grafting increased the grafting success of grape cuttings (RASHEDY, 2016).…”

In addition, the incubation of grafted partners two weeks before grafting increased the grafting success of grape cuttings (RASHEDY, 2016). Grafting date is one of the factors that greatly affected the success of grape grafted cuttings, as Singh and Kaur, (2018) indicated that grafting grape cuttings during the third week of February showed superiority in the success rate and other parameters of vegetative growth compared to the grafts o solo caloso obteve sucesso de enxertia em 72,9%, 68,55% e 77,94% em comparação com o túnel caloso 37,3%, 45,9% e 55% para sem sementes Flame, sem sementes Thompson e sem sementes Crimson, respectivamente como média de ambas as estações.…”

“…포도나무 접목 방법은 크게 혀접(설접, tongue grafting, whip-and-tongue grafting), 절접(깍기접, veneer grafting), 할접(짜개접, cleft grafting, wedge grafting) 등의 인력 접목(manual grafting)과 W자형, 혀모양형(N자형 설접), 오메가형(Ω자형, omega grafting) 등의 기계 접목(machine grafting)으로 나눌 수 있는데 [1,10,18], 최근에는 뿌리 없는 가지를 대목으로 하거나 혹은 뿌리 없는 포도 대목에 포도 품종을 접목한 후 삽목하여 대목의 발근, 접수의 발아 및 대목과 접수의 활착(접목 활착)이 동시에 이루어지게 하는 삽목접(cutting-grafting, grafted cutting)이 국내외 포도 묘목 생산에 활용되고 있다 [13,19,20].…”
