早期的研究 (一)高种椰子早在1930年,Jack曾用选择高产单株和高产椰子种群的方法提高高种椰子产量。约在1950年,根据椰果产量和单果椰干产量选择了代表2％种群的118株椰子作为亲本。从50年代中期至今,就沿用这种方法选择了产量较高的椰子种群,把它作为种果的来源。事实证明,椰子种群选择法能较好地满足人们对椰子种植材料日益增长的需要。试验结果表明,单果椰干率高的植株,其后代单果椰干率也较高。据估算,单果椰 Early Studies A. High Coconuts As early as 1930, Jack used high-yielding coconut stocks and high-yielding coconut populations to increase high-yield coconut production. Around 1950, 118 coconuts, representing 2% of the population, were selected as cows based on coconut yield and yield per coconut. From the mid-1950s to the present, this method has been used to select the higher yield of coconut population, as a source of seed. Facts have proved that coconut population selection method can better meet the growing needs of coconut planting materials. The test results show that the single fruit of high rate of plant coconut, its offspring single fruit rate is higher. It is estimated that single fruit coconut
