为了解杨桃对各种整形修剪措施的响应,以大棚栽培的马来西亚1号甜杨桃为试验材料,于5～9月研究回缩、短截、疏枝、拉枝对杨桃芽体萌发、新梢生长及开花的影响.结果表明：5～7月回缩、短截后侧芽萌发率达到40％～50％,5月中旬回缩和7月中旬短截后发出的新梢80％可当年开花,而7月中旬回缩、疏大枝后萌发的强枝仅有35％左右可当年开花.回缩、疏枝处理能显著提高单果重和果实硬度,而短截处理能显著提高果实硬度.9月上旬采取拉枝措施可以极显著地促使直立枝开花,开花枝条比率较对照提高60％.因此,杨桃不宜修剪过于频繁,对于确需修剪的大棚杨桃,应选择5月进行回缩,适当抹除侧芽和不定芽,疏除弱枝、阴枝;7月后应以适度短截、抹芽、疏除弱枝为主;9月上旬采用拉枝方法促进直立枝开花.合理修剪后杨桃树体光照条件及营养状况得到改善,果实品质明显提高.

Starfruit (Averrhoa carambola L.) is an important fruit for Malaysian export and great attention has been made to improve starfruit fruit quality at Malaysian Agricultural Research and Development Institute (MARDI). The current study used next generation sequencing (NGS) technologies to develop starfruit simple sequence repeat (SSR) from 2 varieties namely B11 and B17 using Illumina HiSeq. The pre-processed reads were de novo assembled to generate approximately 75,000 and 74,000 scaffolds respectively. Total genome size for B11 and B17 were around 345 Mbp and 342 Mbp based on K-mer distribution analysis. In-silico microsatellite mining of each variety has identified more than 17,000 SSR in B11 and B17 respectively. Dinucleotides were the most abundant, accounting for more than 70% of all SSR and repeat motif GA (49%) was most common. A total of 239 SSR primer pairs were designed from contigs larger than 350 nucleotides and tested for amplification. The 30 polymorphic SSRs were used to DNA fingerprint of 12 starfruit hybrids. Polymorphism information content (PIC) ranged from 0.1411 to 0.6838, with an average of 0.3919. The Unweighted Pair-Group Method for Arithmetic Averages (UPGMA) dendrogram clustered 12 starfruit accessions into 2 groups.
