Conventional propagation of bulbous crops must be supplemented with micropropagation to satisfy the requirements of present-day horticulture with respect to fast production of disease-free, superior starting material. Adequate micropropagation protocols for bulbous crops are therefore a sine qua non. The successive steps in micropropagation of bulbous crops are reviewed: initiation, multiplicat...

It has been suggested that respiratory stress is involved in the mechanism underlying the dormancy-breaking effect of hydrogen cyanamide (H2CN2) and sodium azide in grapevine buds; indeed, reductions in oxygen levels (hypoxia) and inhibitors of respiration promote bud-break in grapevines. In this study, we showed that, hypoxia increased starch hydrolysis soluble sugar consumption and up-regulat...

Many endangered plants such as Eryngium viviparum (Apiaceae) present a poor germination rate. This fact could be due to intrinsic and extrinsic seed variability influencing germination and dormancy of seeds. The objective of this study is to better understand the physiological mechanism of seed latency and, through artificial intelligence models, to determine the factors that stimulate germinat...

The successful use of native species in conservation actions depends on basic knowledge their biology, beginning with the identification regenerating individuals field, up to behavior and development from early stages germination. Moreover, seed propagation germination may be limited by occurrence dormancy. objective this work was identify best method overcome dormancy Hymenaea parvifolia Huber...
