Abstract

In order to survey on trends of physical and physiological changes, Alder seeds were collected from different altitudes (200-2000 masl) with a 500 m intervals from Vaz watershed forests around Nour city, Mazandaran province. After cleaning, seed traits such as moisture content (MC%), 1000 SEED WEIGHT (TSW), seed and fruit dimentions, GERMINATION and empty seed percent were determined at seed lab of Caspian forest tree seed centre. Data were analysed by One Way ANOVA based on Duncan test with SPSS. According to results of this survey, all traits were sensible at 99% except of GERMINATION (95%). As, the highest MC% were recorded at 1500 m.a.s.l (14%) and the lowest at 200, 2000 m.a.s.l (6.6, 7.2 res).1000 SW were increased till 1500 masl, then reduced at 2000 m.a.s.l. The highest (0.18 gr) and the lowest (0.1 gr) TSW were recorded at 1500 and 200 m.a.s.lres. The longest (2 cm) and the widest (1.38 cm) fruit were grown at 1500 and the shortest (1.3 cm) and the narrowest (.74 cm) at 200 m.a.s.l. GERMINATION didn't show any special corelation with altitude. The highest (62%) were registered at 1500 m.a.s.l and the lowest (23%) at 200 m.a.s.l. According to the resuts of GERMINATION the highest empty seeds (62%) were found at 200 m.a.s.l and the lowest (23%) At 1500 m.a.s.l. Results of this investigation showed that the quality of Alder seeds increased to 1500 m.a.s.l. and then decreased slightly. It seems that similar investigation on the seeds of this species in Caspian region conducted to preparing of SEED QUALITY map which is an indicator of forest quality.
