Curcuma aeruginosa L., popularly known as Travancore starch plant is an underexploited starchy tuber crop belonging to the family Zingiberaceae. An experiment was designed and carried out presently to evaluate the performance of the crop of Curcuma aeruginosa in relation to the status of the planting materials used. Three types of planting materials such as the mother rhizome, primary fingers and secondary fingers of Curcuma aeruginosa collected from the northern districts of Kerala State of India forms the experimental material. Fifteen growth and yield characters were comparatively studied and among them only three such as the number of leaves per tiller, number of primary fingers and diameter of mother rhizome exhibited statistically significant variations in relation to the status of the planting material. The outcome of the present study indicates the advantage of using mother rhizome, primary fingers and secondary fingers as planting materials so that more number of seed rhizomes can be obtained from a single mother plant.

ABSTRACT The growth and yield of taro plants can be influenced by the planting material used, and the use of improper types of planting material can cause plants to be unproductive according to potential yields. The use of planting materials derived from tubers is expected to increase the yield of taro. This study aims to determine the best type of planting material to increase the yield of taro. The experiments were carried out in the villages of Antirogo, Sumbersari, Jember, East Java with an altitude of ± 89 meters above sea level starting in April 2018 to October 2018. The experiment used a Randomized Block Design (RBD) method with 2 treatment factors. Factor 1 is the type of planting material (B), B1: Bulbs; B2: Puppies; B3: Stolon. Factor 2 is taro variety (V), V1: Green Taro; B2: Brown Taro; B3: Purple Line Green Taro. Each repeated 4 times. The results showed that there was an interaction between the use of different types of planting material and varieties that had an effect on tuber weight per plant. The type of planting material has a significant effect on the number of tillers, leaf area, tuber weight, and tube diameter. Varieties significantly affect all observed variables. The treatment that gave the best results was planting material from tubers (B1) and Purple Line Green taro varieties (V3) with tuber yield per plant 362.58 grams (± 14.5 tons/ha).

Effect Of Surface

The rate of pineapple propagation through conventional technique is quite low and time taken and that by seed is apparently hard to germinate. Non-availability of quality planting material is one of the major constraints for expansion of its cultivation area in Bihar. Keeping this in view an experiment was conducted for in vitro establishment for large scale disease free planting materials production. The most commonly encountered problem during in vitro pineapple germplasm establishment is the rate of contamination, which is very high in case of pineapple. Suckers of pineapple cultivar Kew were used as explants for the study. In this experiment the efficiency of three sterilizing agents (Clorox, HgCl2 and NaOCl) at different concentrations and duration was evaluated in terms of number of aseptic cultures. Results revealed that when no sterilant was used all the cultures were contaminated. The contamination of explants significantly decreased with increase in concentration of different sterilants and their time of exposure. The highest survival of explants (58.31±1.71%) were observed when explants were treated with Clorox 40% for 20 minutes which also resulted in 17.89±0.25% and 25.03±2.63%  mortality and per cent contamination respectively. As the duration of Clorox 40% was increased, percent contamination decreased but simultaneously increased the mortality rate at 25 mins of duration. The percent survival also increased when explants were treated with different concentrations of HgCl2 and NaOCl at different time durations. However, NaOCl treatments were less effective as compared to other two sterilants.

Turmeric (Curcuma longa L.) is an ancient spice, native of India and South East Asia used from antiquity as spice and a dye. It is commonly propagated through rhizomes. The availability of disease free quality planting material is scarce during the cropping season (June – September). An experiment was conducted to study the performance of in vitro derived turmeric plants with conventional rhizome under field condition. The results indicated that the tissue culture plants showed better performance over the conventional rhizome planting. Tissue culture plants grew vigorously and taller than conventional type. The highest yield potential was observed in tissue cultureplants (40.83 tons/ha) as compared to the conventional rhizome planting (30.14 tons/ha). The rhizome rot incidence was lower (3.87% ) in tissue culture plants than rhizome-derived plants (25.58% ). However, the agronomic traits observed during the present study in tissue culture plants are stable and rhizome harvested from tissue culture plants can be used as disease free planting materials for further planting.

Fusarium wilt, caused by the fungus Fusarium oxysporum f. sp. cubense (Foc), poses a major threat to global banana production. The tropical race 4 (TR4) variant of Foc is a highly virulent form with a large host range, and severely affects Cavendish bananas. Foc TR4 was recently observed within the Greater Mekong Subregion, after Chinese private companies expanded Cavendish production to the region. In this study, extensive surveys conducted across Laos and Vietnam show that Foc TR4 is still mainly constricted to the northern regions of these countries and is limited to Cavendish cultivation settings. In Laos, Foc TR4 is associated with large-scale Cavendish plantations owned by or involved with Chinese companies through which infected planting material could have been imported. In Vietnam, mostly small-holder Cavendish farmers and backyard gardens were affected by Foc TR4. In Vietnam, no direct link is found with Chinese growers, and it is expected the pathogen mainly spreads through local and regional movement of infected planting materials. Foc TR4 was not recorded on banana cultivars other than Cavendish. The extensively cultivated ‘Pisang Awak’ cultivar was solely infected by VCGs belonging to Foc race 1 and 2, with a high occurrence of VCG 0123 across Laos, and of VCG 0124/5 in Vietnam. Substantial diversity of Foc VCGs was recorded (VCGs 0123, 0124/5, 01218 and 01221) from northern to southern regions in both countries, suggesting that Fusarium wilt is well established in the region. Interviews with farmers indicated that the local knowledge of Fusarium wilt epidemiology and options for disease management was limited. Clear communication efforts on disease epidemiology and management with emphasis on biosecurity practices need to be improved in order to prevent further spread of Foc TR4 to mixed variety smallholder settings.

Data were obtained on the basis of the results of research carried out on the territory of the educational and experimental farm of the Timiryazev State Agrarian University, in Moscow during 2018-2019. As a result of the surveys, the most dangerous diseases and pests of pome crops on the territory of this farm were established. The most resistant apple and pear varieties to major diseases have been identified. Peculiarities of development of alternariosis on pear are described, the harmfulness of the disease on pear and apple seedlings is noted. A possible role in the transfer of alternariosis infection from garden-protective plantations and weed vegetation to fruit trees was noted. A possible role has been established in the transport of septoriosis, powdery dew infection from dicotyledonous weeds plants. The peculiarities of the spread of infection under the influence of wind direction are noted. The results and peculiarities of the application of various methods of scaring birds in the orchard are presented. As a result of route surveys the most harmful weed plants have been identified. The possibility of using herbicides of different mechanism of action in fruit gardens for weed control has been studied. High efficiency and relative safety of application of herbicides of contact action in nursery fields, operational orchards and for control of piglets on fruit trees are shown. Recommendations are given for the use of soil and systemic herbicides of soil in seedlings beds, the first and second fields of the nursery, as well as in the process of production of large-scale planting material and operational orchards of fruit crops. The safety of the herbicides in question is established when used in accordance with the recommended methods of use.

While investigating the biology of the North American species of Hypomolyx, field workers in Manitoba found a vestigial, or short-winged, and a long-winged form under apparently identical conditions in about equal numbers. Although biological differences were nor then apparent, there was doubt as to whether they were dealing with one dimorphic species or with two distinct species, A search for morphological characters brought to light numerous differences between the two forms, supporting the view that two species were present. These differences, a description the previously unrecognized species, and notes concerning the status of the genera Hylobius and Hypomolyx are reported below.

Clusters of galaxies and the large scale filaments that connect neighboring clusters are expected to be sites of acceleration of charged particles and sources of non-thermal radiation from radio frequencies to gamma rays. Gamma rays are particularly interesting targets of investigation, since they may provide precious information on the nature and efficiency of the processes of acceleration and magnetic confinement of hadrons within clusters of galaxies. Here we review the status of viable scenarios that lead to the production of gamma rays from large scale structures and are compatible with the multifrequency observations that are already available. We also discuss the possibility of detection of gamma rays with space-borne telescopes such as GLAST and ground based Cherenkov telescopes, and the physical information that may be gathered from such observations.

Despite a fair amount of conjecture regarding the circumstances that lead to the generation of status orders, most of the previous literature in this area typically has studied the effects of social cues within a laboratory setting. This article analyzes the evolution of the status hierarchy within a large-scale, natural setting. The results of empirical analyses assessing a large online community of software developers show that in the process of status attainment, community members tend to evaluate a focal actor's reputation according to publicly available social references. Ironically, these same social references also work to constrain an actor's status mobility.

The Status

The article is devoted to the study of the process of introducing digital technologies into the work of the People’s Courts of China and the issues of its legal regulation. The judicial system of the modern Chinese state is based on courts of three levels and two courts. Judicial bodies include the Supreme People’s Court, local people's courts, military courts and other special courts. For several years, various digital technologies have been used in all Chinese courts. In addition, since August 2017, special Internet courts have appeared in the PRC (three such courts have now been created in Hangzhou, Beijing and Guangzhou), which consider civil, administrative and criminal cases online without the personal presence of participants. The use of digital technologies in the judicial system of the PRC contributes to its transparency, reducing corruption, combating the spread of coronavirus, increasing the general level of legal literacy of the people. So, the creation of a unified platform for online broadcasting of court hearings online, the public disclosure of court sentences (decisions, rulings) in various categories of cases allows society to control the activities of the people's courts of the country. Considering the case online during the confrontation of the coronavirus epidemic prevents the spread of infection among participants in the process. The experience of China in the large-scale implementation of digital technologies in judicial activity is not only of scientific interest, but also important from a practical point of view for the Russian expert community. The Russian Federation has also embarked on the path of using digital technologies in litigation, but China is following it ahead of the schedule, which is important in terms of studying the results it has achieved and the mistakes made so that the Russian legislator can take them into account in their law-making activities. It is also important that China, in the process of digitalizing its national system, uses exclusively national platforms and databases. Access to information by foreign intelligence services is not possible. The main providers of digital services for the judicial system are also national corporations, which legally have the status of private companies, but in fact they are completely controlled by the СРС.
