“…ABA significantly inhibited shoot growth and induced expression of OsKRP4, OsKRP5, and OsKRP6 [23]. The effect of GA 3 treatments on the quantitative characteristics of Polianthes tuberose was investigated [24] . More recently, a strong connection between N and hormone signaling pathways have been revealed [9] .…”

Proteins possible effects on roots have received little attention. Here, we investigated how externally supplied protein influences root formation of Cinnamomum camphora cuttings. Cultivation matrix was composed of vermiculite, perlite and river sand based on the proportion 2∶ 2∶3. Softwood cuttings were soaked and injected by the bovine serum albumin (BSA). The results demonstrated that the addition of low to intermediate concentrations of protein (≦7.58μ M BSA) increased rooting rate, average number of lateral roots and average root length of cuttings. However, the rooting rate, the number and length of lateral root decreased at higher concentrations of BSA (≧15.15μM BSA). The treatment of injection was more effective than that of soaking. The endogenous hormones (ZR, IAA, ABA, GA) content of the cuttings rapidly decreased after cutting. On the different days after cutting, four endogenous hormones decreased to the lowest value respectively. Low to intermediate concentrations of BSA will alter the content and proportion of 4 endogenous hormones and be conducive to root development. But the higher concentrations of exogenous BSA changed the content and proportion of 4 endogenous hormones was not in favor of root formation.

“…It is an ornamental bulbous plant native to Mexico which was dispersed around the world in the XVI century (Barba-González et al, 2012). It has garnered popularity as a cut flower in various countries and it is commercially grown in Kenya, Iran, India, and Mexico for export to countries such as the United States, Europe, and Japan (Kumar et al, 2010;Hassanpour et al, 2011;Murrithi et al, 2011).…”

ResumenSe cosecharon espigas de nardo (Polianthes tuberosa L.) 'Perla' con dos flores basales abiertas, fueron sometidas a tratamientos de compresión con 70, 140 y 210 Pa; posteriormente se les aplicó un tratamiento de solución pulso de sacarosa al 20% junto con un tratamiento de Ethylbloc ® (1 bolsa con 0.014% de ingrediente activo (1-MCP)) por 24 h y se evaluaron algunos cambios fisiológicos (tasa de producción de CO 2 , etileno, consumo de agua y peso fresco relativo) en florero durante seis días. Adicionalmente se formaron dos grupos de espigas de nardo, en ambos no se aplicó la compresión, el primer grupo recibió solución pulso y el segundo no se aplicó solución pulso, este último fue considerado el testigo. Las espigas de nardo mostraron incrementos en la velocidad de respiración y producción de etileno similares a flores climatéricas. Las espigas sometidas a compresión superior a 70 Pa mostraron entre 31 y 47% mayor velocidad de respiración y entre 26 y 29% mayor producción de etileno comparadas con las que recibieron el tratamiento testigo. El porcentaje de peso inicial (7 y 11.5%) y consumo de agua (21 y 71%) fue significativamente mayor en las flores sometidas a compresión, con respecto al testigo. Se concluye que el daño mecánico por compresión incrementa la producción de etileno y velocidad de respiración, así como Abstract 'Perla' tuberose (Polianthes tuberosa L.) sprigs were harvested with two open flower buds. They were submitted to compression treatments with 70, 140, and 210 Pa; subsequently, a 20% sucrose pulse solution treatment was applied alongside an Ethylbloc ® treatment (1 bag with 0.014% active ingredient (1-MCP)) for 24 h. Some physiological changes were evaluated (CO 2 and ethylene production indices, water consumption, and relative fresh weight) in the flower vase over the course of six days. Furthermore, two groups of tuberose sprigs were formed, compression not being applied to either. The first group received pulse solution whereas the second group did not, the latter being the control group. The tuberose sprigs showed increases in the respiration speed and ethylene production similar to climacteric flowers. The sprigs subjected to compression above 70 Pa showed between 31 and 47% greater respiration speed and between 26 and 29% greater ethylene production compared to the sprigs that received the control treatment. The percentage for the initial weight (7 and 11.5%) and water consumption (21 and 71%) was significantly greater in the flowers subjected to compression compared to the control group. It can be concluded then that the mechanical damage due to compression increases 104 Rev. Mex. Cienc. Agríc.
