“…Prior to micropropagation of recalcitrant seedlings or older trees, a rejuvenation of the stock plant by serial grafting or cutting cycles is most needed (Evers et al 1993;Greenwood 1987;Hackett 1985;Mc Cown 2000;Vermeer 1991;Vieitez et al 1994;Zsaczek et al 2006). However, despite preliminary rejuvenation, microcuttings keep in their memory the physiological age of the original stock plant, which can be expressed for example in a plagiotropic growth or in a total absence of rooting (Fouret et al 1984;Franclet et al 1987;Franclet and Franclet-Mirvaux 1992;Pierik 1990;Vermeer 1991).…”

The loss of orthotropic morphogenesis renders such microcuttings unsuitable as they fail to develop into vigorous trees.…”

“…At the other extreme are the highly episodic northern oaks (Quercus), walnuts/hickories (Juglans, Carya), northern pines (Pinus), spruces (Picea) and firs (Abies), which have only rarely been successfully microcultured as shoot cultures (Driver and Kuniyuki, 1984;Vermeer et al, 1991). As seedlings of such species often will not develop the engrained episodic growth character until shoot growth is arrested by seasonal dormancy requirements (Borchert, 1991;Remphrey, 1989), greater success with episodic species can be achieved if highly juvenile source plants (preferably embryonic) are utilized.…”

As a general group, long-lived perennial plants probably present the most challenging obstacles to the researcher, breeder or propagator utilizing microculture as a tool. These challenges appear during all stages of the microculture process, but are probably most resplendent during the stabilization phase. What may be particularly frustrating is that much of this 'recalcitrance' is genetically driven and is thus difficult to control by environmental and nutritional manipulations in microculture. Perennials have complex seasonal cycles and life cycles, which complicate control of their growth in microculture. As shoot cultures have provided useful tools for overcoming these limitations, the inability to establish stabilized shoot cultures is a major form of recalcitrance. Plants having seasonal growth dynamics dominated by strong episodic or determinant shoot growth are some of the most recalcitrant species because stabilized shoot cultures cannot be readily generated. In some cases, episodic growth may be tied closely to phase state and can thus be controlled by manipulating phase; nevertheless, adequate controls have not been identified for many problematic plants. Another trait contributing to recalcitrance of perennials is the relatively slow growth rate in microculture. Slow growth complicates such procedures as selection of transformed tissues. The high phenolic content of many perennial tissues can interfere with the efficacy of transgenic traits such as b-glucuronidase. Developmentally determined growth characteristics such as plagiotropism may persist through all stages of microculture and complicate the recovery of commercially useful micropropagules. Although some technical approaches can occasionally circumvent immediate microculture limitations, general solutions await the development of a deeper understanding of physiological bases of such genetically predetermined phenomena.
