“…4a and b). IBA often increases the root or shoot weights of cuttings (Bredmose et al, 2004;Dias et al, 2011;Holanda et al, 2012;Saffari and Saffari, 2012). However, high IBA doses reduce the root and shoot weight of C. citriodora, C. torelliana and Ficus roxburghii cuttings (Trueman and Richardson, 2008;Rana and Sood, 2012) and reduce the shoot weight but not the root weight of Grindelia chiloensis and Pinus elliottii × P. caribaea cuttings (Wassner and Ravetta, 2000;Hunt et al, 2011).…”

“…This had important implications for subsequent performances of the cuttings. It is well established that exogenous auxin promotes root formation in many plants (Bredmose et al, 2004;Browne et al, 2000;Rosier et al, 2004). In vitro experiments on artichoke have also proved that NAA is an effective auxin for promoting rhizogenesis (Brutti et al, 2000).…”

A research project was conducted at the University of Tuscia, Viterbo (central Italy), to set up a vegetative propagation system for producing diseasefree artichoke transplants (Cynara cardunculus var. scolymus) of the Romanesco type (cultivar C3). The system included the following steps: 1) micropropagated plantlets were grown in a soilless culture year-round in greenhouse conditions, starting at the end of August; 2) stock plants were periodically treated with a chemical growth regulator [6-benzylamino purine (BA)] and then cut back at the collar level to promote offshoot production; 3) offshoots were periodically harvested and cold stored; and 4) cuttings were rooted at the end of spring under conditions of high humidity in multi-pack trays so as to be ready for summer transplanting. Results showed that the foliar application of BA to the stock plants increased the offshoot number quadratically to 200 mg·L-1. The rooting percentages of cuttings and root growth were enhanced by raising the cutting weight class (30-45 g) and by the application of naphthaleneacetic acid (NAA) to the cutting root zone at a rate of 2000 mg·L-1. The percent rotten cuttings increased as the 2 °C cold-storage time increased from 30 to 150 days. Similarly, the percentage of rooting and root growth decreased approximately from 60 to 150 days.

“…Most frequently, a rise in air and soil temperatures is subsequently required to alleviate bud ecodormancy and for bud burst and shoot development to resume (Lang et al 1987). Under greenhouse growth conditions where ecodormancy is already overcame, the use of high root temperatures (Bredmose, Kristiansen & Nielsen 2004; or high air temperatures (Moe 1972;Marcelis-van Acker 1995) still hastens axillary bud burst in rose.…”

Light and temperature are two environmental factors that deeply affect bud outgrowth. However, little is known about their impact on the bud burst gradient along a stem and their interactions with the molecular mechanisms of bud burst control. We investigated this question in two acrotonic rose cultivars. We demonstrated that the darkening of distal buds or exposure to cold (5°C) prior to transfer to mild temperatures (20°C) both repress acrotony, allowing the burst of quiescent medial and proximal buds. We sequenced the strigolactone pathway MAX-homologous genes in rose and studied their expression in buds and internodes along the stem. Only expressions of RwMAX1, RwMAX2 and RwMAX4 were detected. Darkening of the distal part of the shoot triggered a strong increase of RwMAX2 expression in darkened buds and bark-phloem samples, whereas it suppressed the acropetal gradient of the expression of RwMAX1 observed in stems fully exposed to light. Cold treatment induced an acropetal gradient of expression of RwMAX1 in internodes and of RwMAX2 in buds along the stem. Our results suggest that the bud burst gradient along the stem cannot be explained by a gradient of expression of RwMAX genes but rather by their local level of expression at each individual position.
