Utjecaj vegetativnih podloga različite bujnosti na kvalitetu ploda trešnje sorte Lapins

Abstract

In the experiment, the \u27Lapins\u27 cherry variety was grafted on six rootstocks of different vigour (F12 / 1, Maxma 14, PiKu 1, Gisela 5, Weiroot 13 and Weiroot 158). The orchard was in full production (8 years after planting) and was planted at a distance of 5 x 3.5 m. The orchard was not irrigated. Samples were analyzed at full maturity. The study showed a significant impact on almost all parameters of fruit quality. The largest fruits were on the rootstock F12 / 1 and Gisela 5. The color indicators of the skin and flesh depended relatively little on the rootstocks. In the chemical composition, greater differences were manifested in the soluble dry matter, on W13 and PiKu 1 being highest, in which the vitamin C content was also higher. The largest differences were found in the content of phenol (199.0 mg / kg on the rootstock PiKu 1, and 68.3 on the rootstock W158) and in the content of neflavanoids (231.7 mg / kg on the rootstock PiKu 1, and 119.5 mg / kg on F12 / 1).U pokusu je bila trešnja sorte Lapins cijepljena na šest podloga različite bujnosti (: F12/1, Maxma 14, PiKu 1, Gisela 5, Weiroot 13 and Weiroot 158). Voćnjak je bio u punoj rodnosti (8 godina nakon sadnje) a posađen je na razmaku 5 x 3,5 m. Voćnjak nije navodnjavan. Uzorci su analizirani u punoj zrelosti. Istraživanje je pokazalo značajan utjecaj na gotovo sve parametre kakvoće ploda. Najkrupniji plodovi su bili na podlozi F12/1 i Gisela 5. Pokazatelji boje kožice i mesa su relativno malo ovisili o podlozi. U kemijskom sastavu veće razlike očitovale su se u topivoj suhoj tvari, pri čemu je veća bila W13 i PiKu 1 kod kojih je i sadržaj C vitamina bio veći. Najveće razlike očitovale su se u sadržaju fenola (199,0 mg/kg na podlozi PiKu 1, a 68,3 na podlozi W158) te u sadržaju neflavanoida (231,7 mg/kg na podlozi PiKu 1, a 119,5 mg/kg na podlozi F12/1)
