Productivity of plants is determined by multiple factors that directly affect one another, therefore yield variability may be high and difficult to predict. Most often, however, a lower crop yield is achieved in the notillage system than in the ploughing system. An exact field experiment was undertaken to determine the yield and chemical composition of pea seeds sown under conditions of: 1) conventional tillage – CT (shallow ploughing and harrowing after the harvest of previous crop, pre-winter ploughing in winter); 2) reduced tillage – RT (stubble cultivator after the harvest of previous crop); and 3) herbicide tillage – HT (only glyphosate after the harvest of previous crop). A cultivation unit was applied on all plots in the springtime. Pea seed yield was higher by 14.1% in the CT than in the RT system and by 50.5% than in the HT system. The CT system was increasing the plant number m–2, number of pods and seeds m–2, seed mass per plant, and 1000 seeds mass, compared to the other systems. Protein content of seeds was at a similar level in all analyzed tillage systems, but was affected by the study year. In turn, the mineral composition of seeds was determined by both tillage system and study year. The seeds harvested from CT plots contained more phosphorus and iron, those from RT plots – more calcium and zinc, whereas those from HT plots – more phytate-P, potassium, magnesium, and copper, compared to the seeds from the other plots

Broad bean (Vicia faba L. “Inovec”) seeds were artificially aged by means of storage at 30 %, resp. 25 % water content at 25 °C for 7-days to study the consequences on germination, root length and frequency of chromosomal aberrations. Under these conditions, significant changes in all parameters were observed. An increase of frequency of chromosomal aberrations in ana-telophase cells was confirmed by evaluation of c-metaphase cells. Synergic effect of artificial seed ageing was studied on different harvests of old seeds. Possible principles of this effect on cell level are discussed.

The tomato leaf miner, Tuta absoluta Meyrick (Lepidoptera: Gelechiidae), is one of the most destructive pest of solanaceae and it prefers tomato (Solanum lycopersicum L.). The aim of the current study was to investigate the effects of a wide range of seed proteinaceous extracts from different plant families against T. absoluta α-amylase activity. The effect of pH on the inhibitory activity of seed extracts showed that seed extracts of amaranth along with a wheat cultivar (Alvand, Aflak, Sarvdasht, Alborz, and Kavir) produced more than a 50% inhibition of the insect amylase. Aflak wheat seed extract at 10 μg, inhibited 81% of the insect amylase. This percent was the highest inhibition achieved. The other proteinaceous seed extracts had a lower effect on the enzymatic activity. Probit analysis showed that Aflak, Kavir, Alborz, Alvand, Sarvdasht, and amaranth inhibited the amylase activity with an I50 of 1.94, 3.24, 3.46, 3.31, 4.97, and 15.39 μg, respectively. The effect of pH on the inhibition of the α-amylase showed the highest inhibition of Amaranth and wheat, at a pH value of 8.0, which corresponds to the pH of the insect’s gut. Gel electrophoresis assays confirmed the spectrophotometric assays showing that the α-amylase of the insect gut was affected by the presence of the seed extracts. In the gel assay, a high concentration (14 μg protein) of amaranth proteinaceous seed extract greatly decreased the intensity of the α-amylase band. A high concentration of the Aflak wheat cultivar (10 μg protein) caused the disappearance of the amylase band in the gel. Thus, it is concluded that the physiochemical environment of the insect gut affects the interaction between digestive α-amylase and the metabolites. The experiments showed that seed proteinaceous extracts from non-host plant species, produced more inhibition of the insect amylase when compared to the host plant species. It appears that with evolution, adaptation took place so that insect/s could overcome the plant metabolites.

In the course of germinating plant seeds - if the deuterium (D) concentration in the germinating medium (water) is lower or higher than in natural water (150 ppm) - the length and mass of seedlings (coleoptil, epicotyl, root) proportionally decrease. The cause of the decrease owing to the changed D concentration is explained partly on energetic - partly on free radical basis and proved by measuring. In waters with lower or higher than natural D concentration the energy supply decreases while the free radical formation increases. Free radicals exert their influence by inactivating the bios substances (e.g. auxin) through oxidation. This seems to explain the mechanism of the ensuing changes.

Morus genus includes more than 20 species, some of which are commercially important mulberries with different fruit color and shape. Even though the trees of those species are propagated by rooting of cuttings in practice, mulberry seeds are of importance for breeding studies and rootstock seedling propagation. For that reason, this study was conducted to improve the seed performance of four mulberry species by different pre-sowing treatments including; 3% KNO3, GA3 at 500 ppm, organic priming with herbal tea brewed from marigold flowers petals and hydro priming. Results of the parameters of emergence characteristics and seedling vigor were evaluated. According to the results that varied between different species and pre-treatments, since emergence percentage and time, and seedling vigor were improved by the treatments, it was concluded that pre-sowing applications, especially GA3 and hydro priming, were beneficial in improving the seed performance of mulberry species included in the study.

The nutrient composition of some neglected and less familiar plant seeds was studied. The seeds showed wide variation in constituents and could be compared with commonly consumed food articles. The protein content ranged írom 29.2 g /kg in Callitris intratropica to 253.5 g/kg in Percopsis elata, while the carbohydrate content was found to be between 330.5 g/kg and 734.8 g/kg in P. elata and Dracena mannii, respectively. The highest fat and fibre content of 215 g/kg and 290.5 g/kg occurred in P. elata and C. intratropica, respectively. P. elata, D. mannii and C. intratropica promises a good source of protein, carbohydrate and fibre, respectively. The legumes showed high ash content but most seeds were rich in Mg, K and F and defficient in Na and Cu. Investigation of the antin utrients and possible toxic effects of the seeds is necessary before their full utilisation.
