Sucrose Metabolism Enzymes Affect Sucrose Content Rather than Root Weight in Sugar Beet (Beta vulgaris) at Different Growth Stages

The herbicide 2,4-D [(2,4-dichlorophenoxy)acetic acid] was applied as sublethal rates to sugarbeets(Beta vulgarisL. ‘Mono Hy D2’) in the field at different growth stages to determine its effect on growth and yield. The greatest reduction in top growth occurred when the highest rate of 2,4-D, 0.07 kg/ha, was applied to the oldest plants (12-leaf stage). All rates of 2,4-D reduced the components of sucrose yield (percentage sucrose, percentage purity, and root weight) to the extent that, together, the three components contributed to a significant reduction in recoverable sucrose. The yields of recoverable sucrose were reduced 6.8, 7.8, and 13.2% by the 0.017, 0.035, and 0.07 kg/ha rates, respectively.

Number Of Leaves

Weed infestation is a major problem and matter of concern as it reduces yield as well as quality of many crops including sugar beet. Manual weeding is very tedious, costly, time consuming and most probably non-availability of trained and skillful labor is another issue. Keeping in view these facts, an experiment was performed to evaluate the efficacy of dual gold on the weed biomass (gm-2) and on the growth and yield components of sugar beet (Beta vulgaris L.) cv. California-KWS during 2013-14 and 2014-15. The study was performed using RCBD having five treatments and three replications. The treatments included different application times (pre-emergence application and application after 15, 30 and 45 days after emergence) of dual gold (s-Metolachlor) and a control (weedy check). Data were recorded on fresh and dry weed biomasses (g m-2), number of leaves plant-1, leaf area plant-1 (cm2), leaf and root weights plant-1 (g), sucrose%, TSS%, root and sugar yields (t ha-1). The results showed significant variation among the treatments for all parameters during both years of study. Among the treatments the dual gold (s-Metolachlor) applied as pre-emergence reduced weed fresh and dry biomasses (g m-2) and also enhanced number of leaves plant-1, leaf area (cm2), leaf and root weight plant-1, sucrose%, TSS%, root and sugar yields (t ha-1) during both years. Hence it is concluded that dual gold (s-Metolachlor) applied as pre-emergence is best for eradicating weeds at early stages of growth and hence improving yield and quality of sugar beet under Dera Ismail Khan Conditions.

Final Yield

Mixtures of 5-amino-4-chloro-2-phenyl-3(2H)-pyridazinone (pyrazon) plus 2,2-dichloropropionic acid (dalapon) were applied to sugarbeets (Beta vulgarisL.) at three growth stages 1 year and six growth stages another year. The growth of tops and roots was retarded most when sugarbeets were treated in the two-leaf stage of growth. The weight of tops and roots was reduced 43 and 50%, respectively, 6 weeks following an application of a mixture of 3 lb/A each of pyrazon and dalapon. However, when these sugarbeets were sampled 2 weeks later, the tops and roots weighed only 4 and 12% less, respectively, than the untreated controls. Furthermore, the early suppression in the growth of sugarbeets for 3 to 8 weeks following herbicide treatment had no effect on final yield of roots, pounds of sucrose, or sucrose content at harvest.

<p>The continuous trend of global warming and increasing interest toward cultivating sugar beet (Beta vulgaris L. ssp. vulgaris var. altissima Döll) in tropical regions led us to conduct this study to investigate the effect of high temperature on sugar beet at initial growth stages. Thirty one genotypes were incubated at two temperatures (20 °C and 30 °C) in laboratory for germination test. The same genotypes were assessed for physiological parameters at 30 °C in greenhouse, too. Increasing temperature decreased germination indices with a high variability among the genotypes. Seed vigor index and seminal root length were decreased higher than other indices. The genotypes with higher greenness index had higher total dry mass, leaf area and leaf temperature depression (LTD), and those with higher seed vigor index indicated great quantum efficiency of PSII (Fv/Fm) values. ‘S1-92521’ produced high records in both laboratory and greenhouse experiments. Although ‘S1-92521’ showed good tolerance in both laboratory and greenhouse experiments, totally, sugar beet genotypes had different performance at two experiments. According to the results, seed vigor index could be used as a screening tool in laboratory, and LTD and Fv/Fm were considered as good criteria for screening heat-tolerant genotypes in greenhouse.</p>

Abstract Mungbean is an important pulse crop and commonly grown in Asia. Drought affects mungbean growth and yield at at different growing stages and various levels through physiological traits and gene expression. In this study, two mungbean cultivars, DX208 and Tam Thanh Hoa, were exposed to drought at the vegetative and flowering stages and assessed for various morphophysiological traits at 8, 12, 15 and 15 days post withholding water and the plant recovery 7 days after re-watering. Differential expression of VrDREB2A gene was observed in leaf and root of two mungbean cultivars under drought condition. Plants used up water more quickly at the flowering stage than the vegetative stage. Drought adversely affected the plant height, leaf number, above-ground plant biomass and root weight with relative reduction to the control by 4.0–85%. Yield components and individual yield reduced significantly by around 50–60% compared to the control. Relative expression of VrDREB2A gene was varied, with stronger expression in leaves and roots when drought imposed at the flowering and vegetative stages respectively. Increase in VrDREB2A expression occurred earlier at 8 days compared with 12 days for drought imposed at the flowering and vegetative stages respectively, resulting in more tolerance of plants to drought at the flowering stage. The results indicate that VrDREB2A functioned as an important transcriptional activator and might help increase the drought stress tolerance of the mungbean plant at various growing stages. Morphophysiological traits can also be used as indicators in screening mungbean for drought tolerance.

The deficiency and toxicity of boron may lead to noticeable yield reduction and quality loss of sugar beet. To evaluate the effects of nano-boron on the root yield and quality of sugar beet, factorial experiment was conducted based on a randomized complete block design with three replications at Urmia University. Treatments were spraying of nano-boron oxide (0, 2, 3 and 4 g L-1) at different growth stages (20, 40, 60, 80 and 100% of ground cover). Increasing levels of boron up to 3 g L-1 resulted in the highest SPAD (Soil Plant Analysis Development) value, leaf number and relative water content. With optimal leaf area (86.47 cm2), the highest yields of root, sugar, white sugar, and technological sugar (144.53, 28.23, 26.19 and 25.32 t ha-1) were determined in the treatment of 4 g L-1 boron at 40% of ground covered. Increasing nano-boron level under different growth stages increased sugar and white sugar contents, on contrary impurities (Na, K and α-amino-N) loss and molasses sugar percentage were decreased. More than 3 g L-1 nano-boron exhibited the highest values of purity. Application of 3 g L-1 boron at 40% of ground cover increased sugar and white sugar contents by 12.45 and 18.72%, respectively.
