中文摘要 | 中國板栗種植面積和產量居世界第一,是世界上重要的果樹之一。同時,板栗也是中國最重要的木本糧食樹種之一,授粉對果實的品質以及結實能力起著至關重要的作用。試驗選用「燕山早豐」為母本,8個品種花粉為試材進行雜交授粉試驗,自然授粉為對照組,研究不同品種花粉對果實品質和果實結實特性的影響。板栗具有隔年結實特性,因此在研究板栗結實特性時取2年平均值作為最終試驗結果。在雜交實驗中,以「紫珀」為父本授粉後,果實著果率最高為86.67%,以「大板紅」為父本授粉後,產量(1.62 kg tree-1)最高,「遷西壯栗」為父本結實率(54.71%)最高,以「燕山早豐」為父本即自交組合結實率最低。與雜交組合相比,自交的單粒重較大。「紫珀」為父本時,果實中脂肪含量最低,粗蛋白含量最高;「遷西早紅」為父本時,可溶性糖含量最高;「燕山短枝」為父本時,果實中支鏈澱粉含量最高;「大板紅」為父本時,果實中直鏈澱粉含量最高。使用灰色關聯法對果實品質和果實結實特性進行綜合排序,以「大板紅」和「燕龍」為父本果實綜合評價最高,自交組合綜合評價最低,自然授粉次之。本研究不僅驗證了花粉直感效應對板栗果實品質和結實特性的影響,同時也為燕山早豐的授粉樹配置提供了理論依據。 |
英文摘要 | The chestnut (Castanea mollissima Blume) has a very large cultivation area and production in the world and is an important nut species crop worldwide. It is also an important food and timber crop in many parts of China. It is known that pollination plays an important role in the fruit quality and fruit productivity of this species. To investigate its role, 8 locally selected pollen sources were tested for their effect on indicators of fruit quality and fruit productivity of 'Yanshanzaofeng' (YSZF) trees. Natural pollination served as the control experiment. Chestnut has the characteristic of alternate year bearing, so data of 2 yr was averaged and used as the final data in the study on chestnut productivity. Cross pollination of these recipient trees by 'Zipo' (ZP) pollen led to the highest fruit set at 86.67%, 'Dabanhong' (DBH) pollen led to the highest total yield (1.62 kg tree-1), 'Qianxizhuangli' (QXZL) pollen resulted in the highest kernel percentage (54.71%), whereas self-pollination resulted in the lowest kernel percentage. Self-pollination led to a heavier single-grain weight than did the other treatments. ZP pollen resulted in the lowest fat and the highest crude protein contents. 'Qianxizaohong' (QXZH) pollen resulted in the highest percentage of soluble sugars. 'Yanshanduanzhi' (YSDZ) pollen resulted in the highest amylopectin content, and DBH pollen resulted in the highest amylose content. The pollen of DBH and 'Yanlong' (YL) ranked best in a comprehensive analysis of all data using a gray relational analysis (GRA), with self-pollination ranking last and natural pollination ranking next to last. Thus, in this study, pollen sources had xenia effects in chestnut, and the results suggested proper species DBH and YL as pollination trees for YSZF. |
