Abstract:The aim of this study was the evaluation of phonological,

The study includes research on the effect of ultrasound on the ability of seed germination and coleoptile development of cereal landraces (fam. Poaceae): oat (Avena sativa L.) brodski, rye (Secale cereale L.) rakotinska, Triticale svetinikolsko and soft wheat (Triticum aestivum L.) govrlevska. The experiment with ultrasound was carried out at frequency of 30-40 kHz on the thermostatic ultrasonic bath. Seeds were sonicated at a constant temperature (25ºC) for 15 min. Ultrasound effect is reflected in the length of the coleoptyl and mesocotyl, although in a good deal is genetically predetermined. Coleoptile length was the longest in Triticale (3.3-5.5 cm) and approximately the same lengths are evident in rye (3.0-6.1 cm). Concerning the mesocotyl the longest one (5.525 cm ± 0.697) is recorded at rye, even significantly longer than control of oat and Triticale. Longer coleoptile of sonicated seeds indicates faster seedling development, good water supply and rapid development and emergence of first leaves. Correlation coefficient showed very high (0.821) and high R2 (67,472%) dependence among variables both, in length of coleoptiles (as dependent variable) and mesocotyl (as independent) with low standard error (0.225). With the simple use of ultrasound the germination period could be shorten, water supply more efficient, the sowing periods will be shorten and good yields even under conditions of climate change with increased temperatures could be achieved

In this paper, we present the results of the phenological characteristics (flowering and ripening time), fruit characteristics (fruit mass, length, width and hardness, length of fruit stalk, number of seeds in fruit, fruit colour and taste and content of stone cells) and chemical characteristics of fruits (soluble dry matter, total sugar and total acids) of 7 traditional pear varieties (Carigradsko avche, Evropsko avche, Letna kajkushka, Karamanka, Vodenka, Zimnica and Zimska kajkushka) in the Skopje region. In the Skopje region, the analyzed pear varieties start to flower in the first decade of April. The pear variety Carigradsko avche flowered at the earliest and Zimnica at the latest. According to the ripening time, the varieties Carigradsko avche, Evropsko avche, Letna kajkushka and Karamanka are summer pear varieties, Vodenka is an autumn variety, Zimnica and Zimska kajkushka are winter varieties. The pear Zimnica had the biggest fruits. The pears Carigradsko avche, Evropsko avche, Karamanka and Vodenka had long fruit stalks. Only the variety Zimska kajkushka contains high quantity of seeds in the fruits. The highest quality fruits, juicy, with very fine to excellent taste, are met in the pears Vodenka and Karamanka. Statistically significant differences among the examined pear varieties for all fruit characteristics were found.
