Experiments were conducted to elucidate the hormonal induction and regulation of rhizome growth in rhubarb (Rheum rhabarbarum L.). It was found that ethylene is the key regulator of rhizome induction and development. The role of jasmonic acid (JA) and its interaction with ethylene in rhizome induction and growth were also examined. Both ethylene and JA have a significant effect on promoting rhizome formation in vitro. Conversely, the ethylene biosynthesis inhibitor aminoethoxyvinylglycine (AVG… 

Effects of chlorocholine chloride and prohexadione-Ca on rhizome growth and lateral bud production in Iris germanica L.

This study indicated that prohexadione-Ca promoted rhizome growth and the accumulation of sucrose and starch before summer dormancy, then significantly accelerated the production of lateral buds.

This review summarizes the current knowledge of the application and properties of jasmonates under in vitro conditions in terms of cell division, explant growth, proliferation ability, storage organ formation and stress response.

Effect of methyl jasmonate on gummosis in petioles of culinary rhubarb (Rheum rhabarbarum L.) and the determination of sugar composition of the gum

This study aimed to know the key chemical compound influencing gummosis in petioles of intact growing culinary rhubarb (Rheum rhabarbarum L.) with special emphasis on its sugar composition. The

Moderate abiotic stresses increase rhizome growth and outgrowth of axillary buds in Alstroemeria cultured in vitro

It is reported here that moderate abiotic stresses stimulate both rhizome growth and outgrowth of lateral rhizomes, and accordingly increase multiplication in Alstroemeria.

The effects of explant rotation, medium types, JA and GA3 additions on in vitro microtuber production from potato (Solanum tuberosum L.)

This study investigates the effects on the in vitro microtuber formations of Solanum tuberosum L. cv. Marfona species, effected by the direction of planting the explants (horizontal or vertical), the

Breaking Dormancy and Effects of Shade Level and NPK Fertilizer Rates on Yield of Zingiber zerumbet (L.) Smith (Lempoyang)

The results showed that BAP at 100mg/L and ethephon at 300 mg/L performed better than the other compound concentrations tested in promoting the breaking of bud dormancy, and a significant interaction effect was observed between shade levels and NPK fertilizer rates in all the growth parameters examined.

Somatic embryogenesis and bulblet production in Narcissus papyraceus cv. Shirazi: effect of plant growth regulators, light intensity, sucrose concentration, methyl jasmonate and anti-gibberellins

This study developed a suitable method for the production of somatic embryos and bulblets in Narcissus papyraceus cv through vegetative methods and found none of the scales produced bulblet production in dark at any sucrose concentration.

Ácido abscísico y sacarosa afectan la formación in vitro de túberos en plantas de ñame (Dioscorea rotundata Poir.)

Sucrose dose induced the highest number of microtubers, while plants cultured in a medium supplied with 90 g L-1 of sucrose developed more stems, leaves and roots, and the analysis of variance and Duncan´s Multiple Range Test showed that plant growth variables as well as microtuber number were significantly affected by ABA/sucrose levels.

Cloning, characterization, and expression of LeEIL-1, an Arabidopsis EIN3 homolog, in Lithospermum erythrorhizon

Tissue-specific expression analysis indicates that less LeEIL-1 mRNA accumulated in the stem and leaf than in the root, where shikonin was biosynthesized, implying that LeEil-1 could be a possible reverse genetic target for revealing the relationship between ethylene and shik onin formation.

In vitro induction of minitubers in yam (Dioscorea cayenensis- D. rotundata complex)

Two methods were used to produce yam minitubers from two different yam cultivars using in vitro culture techniques and the presence of jasmonic acid in the culture medium was found to be essential for yam tuberization, as well as for the germination of yam microtubers.



CCC and Prohexadione-Ca Enhance Rhizome Growth and Lateral Bud Production in Rhubarb (Rheum rhabarbarum L.)

Both Prohexadione-Ca- and CCC-induced rhizome growth enhancement could possibly be due to their known role as GA biosynthesis inhibitors or through increasing photosynthetic efficiency and preferentially reallocating carbohydrates to the rhizomes.

Interactions between jasmonates and ethylene in the regulation of root hair development in Arabidopsis.

The results suggested that JAs promote root hair formation, through an interaction with ethylene.

Adventitious rooting in hypocotyls of sunflower (Helianthus annuus) seedlings. III. The role of ethylene

It is concluded that the wound-induced increase in ethylene, seen within 3 h of production of the cuttings, is a key stimulatory factor in the formation of root primordia.

Effect of growth regulators on growth, flowering and rhizome yield of ginger ( Zingiber officinate Rosc)

Results showed that GA 3 inhibited flowering and shoot emergence while ethrel had no effect on flowering but enhanced shoot emergence and application of CCC at 250 ppm significantly improved rhizome yield by 36.4%.

Effects of jasmonic acid and its methylester on in vitro microtuberisation of three food yam (Dioscorea) species

Microtuberisation was supported in all three species by adding either JA or MeJA to the medium and MeJA applied as a vapour strongly inhibited microtuber differentiation in D. rotundata and D. cayenensis yams.

Induction of tuberisation in vitro with jasmonic acid and sucrose in an Australian terrestrial orchid, Pterostylis sanguinea

In vitro tuber formation of Pterostylissanguinea can be improved by combined addition of appropriate levelsof JA and sucrose to OMA, which will aid in rapid in vitrotuberisation of terrestrial orchids.

Jasmonic acid stimulates shoot and bulb formation of garlic in vitro

Results show that JA might play an important role in the formation of storage organs in plants, in this case on garlic bulbs, and significantly enhanced the shoot and bulb development in concentrations from 1–10 μM.

Promotion of petunia (Petunia hybrida L.) regeneration in vitro by ethylene

Ethylene appeared to play a role on rooting of petunia microshoots in vitro in an auxin-free medium and at low levels (0.01–1 ppm) it had no influence on rooting.

Effect of Methyl Jasmonate on Morphology and Dormancy Development in Lily Bulblets Regenerated In Vitro

In this lily, high concentrations of methyl jasmonic acid (MeJA) inhibited leaf-blade and scale formation to similar extents and reduced dormancy development in all three lilies, with the largest effect observed in Connecticut King.

The role of gibberellin, abscisic acid, and sucrose in the regulation of potato tuber formation in vitro

It is concluded that GA1 is likely to be the active GA during tuber formation, and ABA stimulates tuberization by counteracting GA, and Suc regulates tuber formation by influencing GA levels.
