ABSTRACT Pollinators are extremely important in agricultural crops because their deficit can affect food production in the world. Consequently, a lot of studies have been emphasizing the importance of the knowledge about the biology of these agents. The tomato stands out among the economically most important crops. Therefore, the objectives of this work were: to identify the pollinators of Solanum lycopersicum in a conventional area of cultivation in the southeast of Minas Gerais State and detect which of these are more representative; to assess the importance of the pollinators' action for the quality of the fruits produced; and discuss practices for conservation to these agents. Fifteen floral visitors were found, with Exomalopsis analis being the most representative. Apis mellifera and Trigona spinipes, although not vibrating bees, also acted as pollinators of Solanum lycopersicum.

Postharvest Loss

Tomato (Solanum Lycopersicum L. (or) Lycopersicon esculentum Mill.) is being a very nutritious and health protective food, are highly perishable nature. Its sensitivity to postharvest loss due to poor handling, diseases and physical injury limits its successful marketing. Therefore, simple technology is required to reduce the postharvest loss of this commodity. The use of edible coatings with bio-extracts appears to be a good alternative preservation technique to extend the mature tomato fruits. This study was, therefore, initiated to investigate the effect of using bio- extracts garlic bulba and capsicum incorporation with coating materials (maize starch and beeswax on physicochemical quality of tomato fruit stored at ambient conditions (temperature 15.5 to 20.2oC and relative humidity of 55.5 to 67.3%). The experiment was conducted using complete randomized design of two varieties (Fetane and Melkashola) and six treatments. The tomato fruits were coated by dipping into solution for 3 minutes. The treatments prepared were on coating solution of MGE( 9.5% maize starch with 0.5% garlic extract), MCE (9.5% maize starch with 0.5% capsicum extract), BCE (9.5% beewax mixed with 0.5% capsicum extract), BGE (9.5% beewax mixed with 0.5% garlic extract), 10% maize starch without bio-extract, 10% beewax without bio- extract and control. The treatment means were tested at significance level of P ≤ 0.05. The effectiveness of bio-extracts with coating materials on physicochemical quality of tomato fruits were evaluated at three days intervals for 30 days. There was a significance difference (P<0.05) between coated and uncoated fruits. All coatings delayed tomato ripening and improved the keeping quality parameters but best results were exhibited by 9.5% with 0.5% BCE followed by 9.5% with 0.5% MGE by maintaining the mature tomato fruit for 30 days. The study showed that the Fetane variety has maintained more quality attribute than Melkashola variety during storage.

Quality Of Food

The explosion of technology allows more manufacture food and variety in the market. However, the massive quantity of food is not essential measure of economic progress because the quality of food is more important when producing food. In realizing food quality along with food quantities, various legal issues related to food security have been arisen. Thus, this paper will be examine the legal issues related to food security from the Islamic perspective worldview. Using a study of documents released by the Food and Agriculture Organization (FAO) and content analysis, there are several legislative issues that have been found regarding food security. Such issues include aspects of food production, exploitation of natural resources, trade, and rights to the food. The apparent impact of these issues has undermined food security and food access, thus prompting food security in various parts of the world. Through an analysis of Islamic worldview, this paper presents the preservation of habluminallah and habluminannas relationships as a basis for addressing the issues discussed. Ledakan teknologi membolehkan bahan makanan dihasilkan dengan lebih banyak dan pelbagai di pasaran. Namun demikian, kuantiti makanan yang banyak bukan ukuran kemajuan ekonomi yang hakiki kerana kualiti makanan lebih utama untuk diambil kira dalam menghasilkan makanan. Dalam merealisasikan kualiti seiring dengan kuantiti makanan, pelbagai isu perundangan berkaitan sekuriti makanan telah timbul. Menyedari perkara berkenaan, makalah ini akan meneliti isu perundangan yang berkaitan sekuriti makanan daripada perspektif tasawur Islam. Dengan menggunakan kajian ke atas dokumen yang dikeluarkan oleh Organisasi Makanan dan Pertanian (Food and Agriculture Organization) (FAO) dan analisis kandungan, terdapat beberapa isu perundangan berkaitan sekuriti makanan yang ditemui. Isu tersebut merangkumi aspek pengeluaran makanan, eksploitasi sumber alam, perdagangan, serta hak terhadap makanan. Kesan ketara isu-isu tersebut telah menjejaskan jaminan keselamatan makanan dan akses makanan sekali gus menggugah sekuriti makanan di pelbagai bahagian dunia. Melalui analisis daripada tasawur Islam, makalah ini mengemukakan pemeliharaan hubungan habluminallah dan habluminannas sebagai asas mengatasi isu-isu yang dibincangkan.

ABSTRACT The 'Ubá' mango tree cultivar is very important for the juice industry in the "Zona da Mata" region of the Minas Gerais State, in Brazil, but problems such as uneven flowering and low yield have discouraged producers. This study aimed at evaluating the effect of paclobutrazol, combined with branch tip pruning, on the flowering induction and quality of 'Ubá' mango tree fruits. Treatments were distributed in a 5 x 2 + 1 factorial arrangement, consisting of five paclobutrazol doses (0 g, 0.50 g, 1.00 g, 1.50 g and 2.0 g per linear meter of canopy), with and without branch tip pruning, in a randomized blocks design, with four replicates. The flowering percentage, number of panicles per branch, total flowers per panicle, male/hermaphrodite flowers ratio, number of fruits per branch and fruit quality were evaluated. Plants treated with tip pruning showed a higher flowering percentage. There was an increase in the flowering percentage in response to the paclobutrazol dose, reaching a maximum level at the dose of 1.62 g per linear meter of canopy. Plants submitted to branch tip pruning had a higher number of panicles per branch. There was an increase in the male/hermaphrodite flowers ratio with increasing paclobutrazol doses. Branch tip pruning increased the number of fruits per branch. There were no differences in fruit quality in response to the paclobutrazol application. It was concluded that the paclobutrazol application at the dose of 1.62 g per linear meter of canopy, combined with branch tip pruning, increases the flowering of the 'Ubá' mango tree and does not change the fruit quality.

<p>As abelhas são os principais polinizadores na natureza, sendo de fundamental importância na condução de muitas culturas agrícolas ao redor do mundo, promovendo várias melhorias na cadeia produtiva da agricultura. A polinização realizada por abelhas contribui para a melhoria da qualidade e/ou a quantidade de frutos e sementes produzidos. Entretanto, apesar de toda importância, as abelhas encontram-se em processo de desaparecimento em várias partes do mundo, principalmente na Europa e em alguns países da América do Norte. Pesquisas recentes estão mostrando um grande declínio das abelhas nativas e abelhas melíferas (<em>Apis mellifera</em>), principalmente como consequência das alterações ambientais, que provocam severos efeitos negativos na disponibilidade de alimentos disponíveis para as abelhas. Assim essa revisão tem como objetivo, reforçar a importância das abelhas da polinização agrícola e alertar sobre a atual situação e o declínio populacional de diferentes grupos desses importantes polinizadores.</p><p align="center"><strong>Population decline of crop bee pollinators</strong><strong></strong></p><p>Bees are the main pollinators in nature, being of fundamental importance of many agricultural crops around the world, causing improvements in the productivity of these crops.

However, despite all importance, the bees are in the process of disappearing in several parts of the world, mainly in Europe and in some countries in North America. Recent surveys are showing a large decline in native bees and honeybees (<em>Apis mellifera</em>), mainly as a result of environmental changes, that cause severe negative effects on the availability of food for the bees. So, this review aims to reinforce the importance of bees in crop pollination, and warn about the current situation and the population decline of different groups of these important pollinators.</p>

Physiological Quality

The human consumption of vegetables in different parts of the world is quite high, among them tomato stands out on a larger scale and not so far, also is cucumber, both with great economic importance. Due to the problems regarding the vigor of many seeds, techniques that seek to improve the establishment of the seedlings in a uniform way have been implemented. One technique is the osmotic conditioning to which the seeds are submitted, for which compound solutions such as polyethylene glycol or potassium nitrate can be used, with which very satisfactory results are obtained under laboratory and field conditions The objective of this investigation was to evaluate the effect of different doses and osmotic solutions on the physiological quality of seeds of tomato (Solanum lycopersicum L.) and cucumber (Cucumis sativus L.) in laboratory and field conditions. The evaluated variables were germination percentage, germination speed index, root length and emergence of seedlings. The tomato seeds were conditioned with PEG-6000 (-0.2, -0.4, -0.6 and -0.8 Mpa) and stored for a 30 days period, and as for the cucumber seeds with PEG-6000 (-0.2 and -0.1 Mpa) and with KNO&sup3; (100 mg and 300 mg) with a storage period of 45 days. It is concluded that, in tomato seeds, germination did not present statistical differences, however, the variables referring to vigor were favored with the conditioning in the presence of PEG-6000 with the (-0.2 Mpa) concentration, while in cucumber seeds the germination percentage was better using PEG 6000 compared to nitrate, while for vigor variables it behaved better in the presence of a concentration of (-0.2 Mpa) of PEG.

Features of soil formation and the specific element composition of the parent rock of podzolized and leached chernozems of the Ryazan region predetermined the specifics of the content of trace elements in the arable soil layer. For example, the content of such important microelements for agricultural crops as molybdenum and manganese is lower than the criteria for the global assessment of the "soil of the world". These microelements are involved in metabolism and enzymatic reactions, their lack leads to both a decreasein crop yields and a deterioration in the quality of crop products. It is possible to correct this situation by using trace element additives in the development of complex methods of agrochemical reclamation of degraded chernozems
