The Apple Tree Root System
Variation in the number of secondary roots per plant The growth of the roots and shoots of apple trees varies between species. The number of secondary roots is an important trait to monitor. In this study, researchers compared the number of secondary roots produced by two different varieties and noted that they differed in their elongation patterns. The number of primary roots and shoots was also measured on a weekly basis. The study used software developed by C. Jourdan and B. Mailhe, which was able to detect new root growth. Each new root was labeled and recorded along with its type and initial two-dimensional co-ordinates. The top spatial co-ordinates and observation date were also recorded. Data was analysed using Excel software. Influence of grafting type on fungal community in apple tree roots In a recent study, scientists analyzed the effects of two types of grafting on the fungal community of apple tree roots . In this study, they observed that when both types were used, th...
