焦核龙眼果实发育的研究─—果实生长型及性状相关分析
Studies on Fruit Development Of Seed-wilted Longan——Correlative Analysis on Fruit Growing Type and lts Characters

摘要: 研究结果表明,“闽焦64-1”、“闽焦64-2”及白核龙眼的果实及各部分组织的鲜重增长都呈单S型曲线。可溶性固形物含量的变化动态是:闽焦64-1、闽焦64-2呈双S型曲线:白核龙眼为单S型曲线。采用相关及通径分析方法揭示了焦核龙眼的果实发育与种子、果皮和假种皮之间的相互关系,发现与荔枝一样,焦核龙眼的果实发育受到从种子一果皮一假种皮的顺序性影响,果皮对假种皮同样存在“球皮对球胆的效应”。Abstract: The research results showed that the fresh-weight increase of Min Jiao 64-1, Min Jiao 64-2and Baihe Lonyan fruits and their seperate parts appeared to be a single S-type curve, The dynamic change of soluble solid content was Min Jiao 64-1and Min Jiao 64-2 appeared a double Stype curve wbereas Baihe Lonyan appeared a single S-type curve.The correlative and path analysis on the relationship between fruit development with seed, pericarp and aril were undertaken.It was found that, similar to Litchi.the fruit development of seed-wilted lonyan was affected in properorder by seed-pericarp-aril,and the effect of pericarp matter on aril just like the one of ball skin on its bladder.
