Optimizing Graft Union Formation between Sweet Potato (Ipomoea batatas) and Bush Morning Glory (Ipomoea carne a ssp. fistulosa) As a Prelude to Chimera Development.

Bush morning glory (Ipomoea carnea ssp. fistulosa) and ornamental sweet potato (Ipomoea batatas Blackie ) were grafted using various procedures. Lanolin pastes containing 3% BA, 3% NAA, and a mixture of 3%BA/3%NAA were tested as a means of promoting adventitious shoot development at the graft unio...

Description
Summary:Bush morning glory (Ipomoea carnea ssp. fistulosa) and ornamental sweet potato (Ipomoea batatas Blackie ) were grafted using various procedures. Lanolin pastes containing 3% BA, 3% NAA, and a mixture of 3%BA/3%NAA were tested as a means of promoting adventitious shoot development at the graft union. Excellent take was obtained with all graft types tested. The growth regulator treatments resulted in marked differences in callus formation at the wounded graft union. Lateral shoot development below the graft union was also affected by the growth regulator treatments. The highest quantity of callus was formed using the mixed paste, while BA enhanced lateral shoot formation below the union. No adventitious shoot development occurred in or near the graft union. Results indicate that in vivo grafting of these two species may not be the best procedure for obtaining interspecific chimeras.
