Preventive measures are most effective methods of plants pathogens control. Broad beans - Vicia faba L. - are infected by Uromyces fabae (Grev.) de Bary ex Fuckel, Ascochyta fabae Speg. and broad bean mottle virus (BBMV) at the Middle part of Russian Federation. Degrees of diseases spread were: for Uromyces fabae (Grev.) de Bary ex Fuckel - 76% (at 2009) and 6,5% (at 2011); for Ascochyta fabae Speg. - 100% (at 2009) and 1,5% (at 2011), for broad bean mottle virus - 23% (at 2009) and 46,3% (at 2011). It is known, that Ascochyta fabae Speg. is spreading by seeds. It has been proved by analysis of broad beans seeds germinated in the humid chamber. The significant negative correlation between the degree of plants affection and the degree of seeds germination has been established (r= -0,49; tr = 3,50>t05 = 2,01). This correlation is significant on 5%-level of significance. Recommendations for treatment of broad bean seeds against Ascochyta fabae Speg have been done for breeders.

Study of morphological parameters of seeds is of interest for the enhancement of quality of produced seeds vegetable Umbelliferae plants. Indicators of the linear dimensions of the embryo, endosperm, seed, and the degree of variability can be used for additional performance of a lot of seeds. Knowledge of morphology of heterogeneity of seeds should be taken into account in their growing, sorting, storage and presowing refinement.

In the process of improving crop varieties, an essential role belongs to the fruit quality, which is expressed by biological and nutritional value of raw material used in fresh or processed condition, Plant disease resistance, high productivity, good morphological and other agricultural features are also important. We have presented the results of technical evaluation of five varieties of pumpkin (Maslicinaia 75, Gleisdorfer olkurbis, frown Prince F1) are grown in the Republic of Moldova. The chemical, physical and technical indexes of fresh pumpkin depending on the variety were investigated. According to the results the variety of products obtained from processing pumpkin (nectars, marinades, candied fruits, pumpkin seed oil) was selected.

The paper presents the results of the Agricultural Department of RAAS and its research institutes, experimental stations, breeding, biotechnology and technology centers in 2011.

Standard is the main normative document regulating the important traits of seeds (germination ability, humidity, purity, regime of storage). This regulatory document provides the technological and economical basis for vegetable production and others features of agriculture.

Edible chrysanthemum is a new plant culture that can be very valuable source of vitamins, mineral substances, particularly potassium and biologically active matters. An extract from foliage of chrysanthemum contains nearly as much antioxidant efficiency as in extract from ginseng.

The technological procedure requirements for cultivation, mechanized harvest, storage and processing of cucumber are determined.

The effect of temperature during seeds germination of some species of Umbelliferae vegetable crops has been studied. There is a different reaction of vegetable crops on the temperature factor: depending on crops and temperature, the number of days until the maximum rate of growth can varied from 7,6 to 22,8 days, and percentage of germinated seeds can varied from 7% to 88%. The effect of temperature on growth of seeds embryo has been studied in different crops. The «degree of underdevelopment of embryo» (DUE) characterized the morphological and anatomical features of embryo varied from 13 to 52%. The temperature coefficient (Q10) for the rate of germination of seeds of vegetable crops of Umbelliferae was 1,23 - 1,82.
