Plant carbohydrate partitioning of Lachenalia cv. Ronina during bulb production

Effect of bulb size on growth, flowering and bulb formation in lachenalia cultivars

“…Rosabeth in 2009), and the number of florets was dependent on bulb size -in all the cases this parameter increased with the larger bulb size (Table 2). Du Toit et al (2004) claim that starch is the major storage carbohydrate in lachenalia cv. Ronina and the concentration of this compound is highly correlated with the total dry weight of a bulb.…”

Low-temperature effect on enzyme activities involved in sucrose–starch partitioning in salt-stressed and salt-acclimated cotyledons of quinoa (Chenopodium quinoa Willd.) seedlings

“…In this context, it has been found that salinity and low temperature induce synthesis of polyols (linear polyhydric sugar alcohols) and cyclitols (cyclic polyhydric sugar alcohols) from the more common storage carbohydrates such as starch and sucrose [13,14]. These observations have led to the suggestion that naturally occurring changes in the carbohydrate status may have an adaptive role in allowing seedlings to survive under saline and/or low-temperature conditions [12,31,38,41]. However, under field conditions stress does not generally come in isolation and many stresses act simultaneously.…”

Management of corm size and soil water content for gladiolus flower production

“…Regarding the used dry matter by the plant, another variable that was not influenced by the studied treatments, Du Toit et al (2004) stated that, for bulbs, starch concentration in the mother bulb started to increase due to photosynthesis performed by active leaves until flowering, decreasing during senescence and death of the aerial part. Considering the data obtained in this study, reasonable results would demonstrate that taller plants with more leaves and longer inflorescences would have used more reserve than others.…”
