Seed Maturation Indicators in Pyracantha crenulata Roxb. in Kumaun Central Himalaya

Fruits of Pyracantha crenulata were collected from two locations varying by approximately 550 m in elevation from south aspect for assessing seed maturation indicators. The mean seed size (lengthxdiameter) across the collection dates varied between 1.61 ± 0.7 and 4.93 ± 0.06 mm2 across both the loca...

Description
Summary:Fruits of Pyracantha crenulata were collected from two locations varying by approximately 550 m in elevation from south aspect for assessing seed maturation indicators. The mean seed size (lengthxdiameter) across the collection dates varied between 1.61 ± 0.7 and 4.93 ± 0.06 mm2 across both the locations. The seed moisture content negatively correlated with germination. The change in fruit colour from dark green to light orange, the range of fruit moisture content (30.43% ± 0.06 to 36.10% ± 0.25) and the seed moisture content between 68.8% ± 0.68 and 71.6 ± 0.62 coincided with maximum germination and appear to be major indicators of seed maturation in Pyracantha crenulata.
