摘要/Abstract

摘要：

以大叶茶品种‘勐海大叶茶’ (Camellia sinensis var. assamica cv. Menghai Dayecha) 种子为材料，进行种子萌发特性的初步研究。研究发现，种皮对‘勐海大叶茶’种子的萌发存在一定的作用，含水量较高时，人为破除种皮有助于种子的萌发，随着含水量的降低，人为破除种皮反而降低了种子的萌发率。‘勐海大叶茶’种子的最适萌发温度为30℃，15℃以下时萌发率较低，容易发生低温伤害，变温处理对提高种子萌发率的效果不明显。基质对大叶茶种子萌发的影响不明显，四种不同种植基质条件下，种子的萌发率趋于相同水平，证明基质类型并非影响种子萌发的关键因子。

关键词: 大叶茶种子, 脱水, 温度, 种皮, 基质

Abstract:

Germination characteristics about Menghai Daye tea (Camellia sinensis var. assamica cv. Menghai Dayecha) were explored in this paper. Results showed that hard seed coat influenced germination. When water content was high, getting rid of seed coat promoted germination percentage, but keeping seed coat became an advantage for seed germination when water content decreased. Optimum germination temperature was 30℃, bellow 15℃ was harmful temperature. The effect of 20/30℃ alternating temperature treatment on raising germination percentage was not notable. Effects of different soil types on germination percentage of Menghai Daye tea seeds were not notable too. Soil type was not a crucial factor during seed germination period of Menghai Daye tea.

Key words: Daye tea seeds, Dehydration, Temperature, Seed coat, Soil type
