Incompatibility in Cultured Explant‐grafts Between Members of the Solanaceae

Abstract: SUMMARYThe development in culture of explant-grafts between compatible and incompatible combinations of three solanaceous species parallels that of the corresponding whole-plant grafts in respect of the pattern of vascular development and the functional status of the vascular system. In culture, incompatible explant-grafts attain greater mechanical strength than corresponding whole-plant grafts, and consequently tbis parameter of their development is an unsuitable criterion for judging the compatibility of exp… Show more

“…The high graft success between eggplant rootstocks and local tomato cultivars of 90 -100% reported in this study is comparable to the worldwide commercial vegetable graft success of 85 -90% using tube method (Oda, 1995). Formation of abundance trans-union xylem or big root systems is reported to account for the high graft success in vegetables (Parkinson et al, 1987;MartinezBallesata et al, 2010). However, the relatively low graft success of 30.9 -50.4% between rootstock Hawaii 7996 and local tomato cultivars at the hardening nursery stage contradicts with previous reports.…”

“…Graft incompatibility is caused by low hydraulic conductance at the union, which reduces water and nutrient transport to the scions (Oda at el., 2005). Several factors are responsible for low hydraulic conductance including small root systems of rootstocks and limited formation or blockage of trans-union xylem connections at the graft union (Parkinson et al, 1987). In Tanzania, grafting technology has the potential to overcome soil-borne diseases, which pose serious tomato yield losses.…”

“…En jitomate la cohesión entre el portainjerto e injerto, como primer evento del prendimiento, está relacionado con la secreción de sustancias pécticas, que proporciona soporte mecánico inicial en el punto de unión (Jeffree y Yoeman, 1983;Parkinson et al, 1987). En la Figura 2a se observa la acumulación de estas sustancias y los restos de las células muertas ocasionadas por el corte, formando una línea de demarcación en la zona de unión, la tinción con fast green muestra una región más intensa.…”

“…En los cortes obtenidos se observa la reabsorción de la línea de demarcación en la inter fase a los 5 DDI, incluso en el corte longitudinal (Figura 2b) se observa que la línea de demarcación se ha reabsorbido en 50%, se aprecia al mismo tiempo el entrelazamiento de las células del porta injerto/injerto, debido al aumento en tamaño de las nuevas células del callo, esto confiere mayor resistencia mecánica en el punto de unión. En injertos de especies frutícolas la reabsorción de la línea de demarcación comienza entre dos y tres semanas después de la injertación (Parkinson et al, 1987). Oda (2002) reportó en injertos de chícharo (Pisum sativum) la reabsorción de la línea de demarcación a los cuatro DDI.…”
