Note 38 — PART IV. NOTICES OF AUTHORS RELATIVE TO TIMBER.

Transplanting having an opposite influence on the young of herbaceous and woody vegetables, in the former when not already rising into stem, retarding, and the latter accelerating or furthering development of the reproductory parts, is a good lesson to reasoners from analogy. The root-fractured herbaceous plants repairing the injury almost immediately, and before the rudiments of the reproductory parts have time for expansion, the greater quantity of moist nourishment afforded by the unsought newly stirred soil, produces a flush of radical leaves, which react to further the extension of the roots. The new rootlets have again more connexion to promote the growth of the radical leaves, and to induce offsets—tillering—from the sides of the bulb, than to nourish or mature the core part, from whence the stem arises—a certain comparative extension and maturity of the core being necessary to the rising of the stem. Thence seeding can be retarded, and life in annuals be continued, ad libitum. On the contrary, in woody vegetables of perennial stem, the reparation of the root-injury takes place slowly, and the evaporation from the stem and elevated branches and leaves exhausting the little moisture afforded by the inadequate root-suction during an entire season, gives time and bias for the germs to pass into reproductory instead of productory organs even the first season.
