The influence of six boron treatments (0, 0.1, 0.5, 2.5, 5.0 and 10.0 ppm) on glucosinolates and reducing sugars was studied in tops and roots of hydroponically grown Snow Ball turnip (Brassica rapa L.). The glucosinolates were determined by quantifying their hydrolytic products, 5-vinyl-oxazolidine-2-thione (goitrin), volatile isothiocyanates, and thiocyanate ion. While growth of plants receiving no boron (0 ppm) was drastically impaired, that of plants receiving 0.1–5.0 ppm boron was equally vigorous; growth was slightly inhibited with 10.0 ppm boron. Mild boron deficiency was manifested as brown-heart in roots of fully-sized turnips from the 0.1 ppm boron treatment although there was no apparent effect on external root appearance or on foliage and plant growth. In roots of boron-deficient turnips, elevated yields of goitrin were found, accompanied by relatively high yields of thiocyanate ion and low contents of reducing sugars.

Two field experiments were conducted from 1986 to 1988 to determine efficacy of herbidices and plant growth regulators for red rice control and suppression in water- and drill-seeded rice. Molinate applied PPI with fenoxaprop applied at panicle initiation (PI) of rice controlled 94 and 86% of red rice in water- and drill-seeded rice, respectively, compared with 79 and 49%, respectively, for molinate PPI alone in the two cultures. Although this treatment injured rice slightly (< 30%), rice so treated produced high yields with improved grain quality. Sequential treatments of molinate PPI followed by sethoxydim applied at PI or amidochlor applied at > 90% heading produced comparable rice yields with improved red rice control or suppression and grain quality in both cultures, compared with PPI molinate. Drill-seeded rice treated with molinate PPI followed by fenoxaprop applied at late boot or MH (maleic hydazide) applied 7 d after heading produced higher yield than rice treated with molinate PPI.

ABSTRACT - There is a little information about sweet sorghum crop behavior under chemical ripeners spraying management. Therefore, the aim of this study was to assess the technological profile of sweet sorghum (cv. CMSXS-646) juice under spraying of plant growth regulators and sampling periods. A randomized complete block experimental factorial design was used, with an additional control treatment (arrangement 2x2+1), corresponding to two chemical ripeners with three-doses for each product, glyphosate (0.2, 0.4, and 0.8 l c.p. ha-1) and methyl-sulfumeturon (10, 20, and 30 g c.p. ha-1), two sampling periods (15 and 30-days after spraying - DAS) and one control treatment (water spraying). After crop harvest, stalks were milled using a hydraulic press and the derived juice was assessed for total soluble solids (°Brix), apparent sucrose (POL), purity (PRT), reducing sugars (RS), total reducing sugars (TRS), fibers (FIB) and recoverable theoretical sugars (RTS). The dataset was subjected to the Shapiro-Wilk, Fisher, Tukey, Pearson and multiple linear regression statistical tests (p<0.05). There was an interaction between causes of variation for almost all assessed characteristics except to RTS, only affected by the sampling period. As conclusion, it is possible to grow sweet sorghum (cv. CMSXS-646) till thirty-days after spraying of chemical ripeners, treated by glyphosate 0.4 l c.p. ha-1 or sulfumeturon-methyl 10 g c.p. ha-1, because these doses caused feedstock with high °Brix, POL, total reducing sugars, purity levels.Keywords: Sorghum spp., phytorregulators, plant growth regulators, glyphosate, sulfumeturon-methyl. PERFIL TECNOLÓGICO DE CALDO DE SORGO SACARINO (cv. CMSXS-646) SUBMETIDO À APLICAÇÃO DE MATURADORES QUÍMICOS E ÉPOCAS DE AMOSTRAGEMRESUMO – Há poucas informações sobre o comportamento da cultura do sorgo sacarino sob manejo de aplicação de maturadores químicos. Portanto, o objetivo desta pesquisa foi avaliar o perfil tecnológico de caldo de sorgo sacarino cv. CMSXS-646 submetido à aplicação de maturadores químicos e períodos de amostragem. Aplicou-se o delineamento de blocos inteiramente casualizados, em esquema de fatorial (2x2+1), correspondente a dois maturadores químicos com três dosagens - glifosato (0,2; 0,4 e 0,8 l p.c. ha-1) e sulfumeturon-metil (10, 20 e 30 g p.c. ha-1); dois períodos de amostragem (15 e 30 dias após aplicação - DAA); e um tratamento controle (aplicação de água). Após a colheita, destinaram-se colmos à moagem, realizada em prensa hidráulica, para extração de caldo; avaliaram-se sólidos solúveis totais (°Brix), sacarose aparente (POL), pureza (PRT), açúcares redutores (AR), açúcares redutores totais (ART), fibras (FIB) e açúcares teóricos recuperáveis (ATR). Ao conjunto de dados, aplicaram-se testes estatísticos, Shapiro- Wilk, Fisher, Tukey, Pearson e regressão múltipla, ao nível de 5% de probabilidade. Houve interação entre as causas de variação para quase todas as características, exceto ATR, influenciado, somente, pelo período de amostragem. Concluiu-se que a aplicação dos maturadores químicos glifosato 0,4 l c.p. ha-1 e sulfumeturon-metil 10 g p.c. ha-1 apresentou um incremento na qualidade da matéria-prima com alto teor de °Brix, POL, açúcares redutores totais e níveis de pureza trinta dias após a pulverização dos maturadores.Palavras-chave: Sorghum spp., fitorreguladores, reguladores de crescimento vegetal,

Purple Alfalfa is an inexpensive, abundant, readily available lignocellulosic material. This work was attempted to develop an efficient combination pretreatment by sequential HClO4–ethyl glycol–H2O (1.2:88.8:10, w/w/w) extraction at 130 °C in 0.5 h and urea/NaOH (urea 12 wt%, NaOH 7 wt%) soaking at −20 °C for 0.5 h for the pretreatment of purple alfalfa. The porosity, morphology, and crystallinity of pretreated purple alfalfa were characterized with SEM, FM, XRD, and FTIR. This combination pretreatment had a significant influence on hemicellulose removal and delignification. The above changes could enhance cellulose accessibility to enzymes and improve the enzymatic digestibility of cellulose. High yields of reducing sugars from pretreated purple alfalfa were obtained at 93.4%. In summary, this combination pretreatment has high potential application in the future.

Supplemental Calcium

The effects of supplemental Ca on salinity tolerance were tested using a Brassica rapa L. landrace, `Sani', which is salt-sensitive. Plants were grown in a continuous aerated hydroponic system with 0.25-strength Hoagland solutions containing 125 mM NaCl plus 0, 2.5, 5.0 or 10 mM CaCl 2. The effects of Ca treatment were significant in reducing Na accumulation in roots, Na+ transport from roots to shoots and in enhancing K and Ca accumulation and transport. The Ca addition also enhanced the selectivities of both K and Ca over Na of accumulation at roots and of transport to shoots. However, supplemental Ca did not alleviate the growth reduction caused by the NaCl salinity. These results suggest that the growth inhibition of salt-treated B. rapa `Sani' is mainly caused by factors other than Na, K, and Ca contents in plants.

The article deals with the study of the effect of the application of the herbicide Granstar Gold 75, w.g. (water-soluble granulate) and plant growth regulator Regoplant on some ecological indicators of ecocenosis of winter wheat sowing (lipid peroxidation reactions in winter wheat plants by the activity of malonic dialdehyde content accumulation, enzymatic activity, total number of rhizosphere bacteria and anatomical structure of winter wheat leaves). The choice of research topic is due to the fact that currently obtaining high yields of winter wheat is closely connected to the widespread use of chemicals, in particular, herbicides, which by their nature are physiologically active substances that can affect both plants and soil microbiota. This, in turn, leads to the search for environmentally safe elements of technologies for growing winter wheat. One such element may be the use of herbicides together with plant growth regulators. The obtained experimental data testify to the protective ability of the growth regulator Regoplant against the winter wheat plants, as evidenced by a decrease in the activity of malonic dialdehyde accumulation, changes in the activity of the enzymatic defense system, decrease the number of epidermis cells and an increase in total rhizosphere bacteria in case of Regoplant use together with Granstar Gold 75, w.g. compared with the experiment variants, where the herbicide was applied without a growth regulator. That is, the use of growth regulator in a mixture with herbicide to some extent eliminates the toxic effect of xenobiotics, which has a positive effect on the state of ecobiosis of winter wheat sowing.

Phd Finger

Abstract Background Plant homeodomain (PHD) finger proteins are widely present in all eukaryotes and play important roles in chromatin remodeling and transcriptional regulation. The PHD finger can specifically bind a number of histone modifications as an “epigenome reader”, and mediate the activation or repression of underlying genes. Many PHD finger genes have been characterized in animals, but only few studies were conducted on plant PHD finger genes to this day. Brassica rapa (AA, 2n = 20) is an economically important vegetal, oilseed and fodder crop, and also a good model crop for functional and evolutionary studies of important gene families among Brassica species due to its close relationship to Arabidopsis thaliana. Results We identified a total of 145 putative PHD finger proteins containing 233 PHD domains from the current version of B. rapa genome database. Gene ontology analysis showed that 67.7% of them were predicted to be located in nucleus, and 91.3% were predicted to be involved in protein binding activity. Phylogenetic, gene structure, and additional domain analyses clustered them into different groups and subgroups, reflecting their diverse functional roles during plant growth and development. Chromosomal location analysis showed that they were unevenly distributed on the 10 B. rapa chromosomes. Expression analysis from RNA-Seq data showed that 55.7% of them were constitutively expressed in all the tested tissues or organs with relatively higher expression levels reflecting their important housekeeping roles in plant growth and development, while several other members were identified as preferentially expressed in specific tissues or organs. Expression analysis of a subset of 18 B. rapa PHD finger genes under drought and salt stresses showed that all these tested members were responsive to the two abiotic stress treatments. Conclusions Our results reveal that the PHD finger genes play diverse roles in plant growth and development, and can serve as a source of candidate genes for genetic engineering and improvement of Brassica crops against abiotic stresses. This study provides valuable information and lays the foundation for further functional determination of PHD finger genes across the Brassica species.
