JOURNAL FREE ACCESSThe author of this paper tried to find whether equal masses of cuttings produce in equal time and under equal environmental conditions, equal quantities of shoots and roots unconditionaly with grape vine (Vitis vinifera Chasselas doré) and he found that the quantity of new shoots and roots approximately proportionates to that of cuttings.
He noticed however this mass relation law is adaptable only within a limit contrarily to Loeb's results. The increase ratio of shoots and roots is. not proportional to the cutting mass, it diminishes little by little at first, rapidly later as the cutting mass grows larger and it ceases when cutting mass reaches to some dimention. The author then considers that the reserved food is available for new shoots and roots except when it is within a morphological distance and outside of this limit it is not usable.
By this fact the author believes that there must be field of nutrition in grape cuttings.View full abstractDownload PDF (627K) -

JOURNAL FREE ACCESS1. Increase of physiological carbohydrate does not necessarily augment the percentage of fertilized berries of Muscat of Alexandria.
2. For weak canes which shell flowers sugar injection is ineficacious to give more fertilized berries to clusters of Muscat of Alexandria.
3. On the contrary for such canes asparagin injection is effective to help the good set.
4. Very vigorous canes increase the percentage of fertilized fruits being injected with carbohydrate as well as moderately vigorous canes do without any injection.View full abstractDownload PDF (351K) -

I Report; Active C, N Mass-Ratio with Reference to the Growth of the EggplantS. SATO1935 Volume 6 Issue 2 Pages 329-364

JOURNAL FREE ACCESSThere are various opinions, theories or hypotheses on the relations between carbohydrates and nitrogen contained in plant to its behaviours. In order to know whether there is any more general and adequate fact or not we postulated“Active C, N”designated as“C, N”meaning the carbohydrate and the nitrogen, without any faults, which are necessary and sufficient for the contructive materials of the plant's growth in question, and the sources of its energy.
Then we formulized an ideal functional equation“W=K_??_C+N_??_m_??_C/N_??_n”between the amount of plant's growth and C, N, limiting some conditions from the special point of view.
For the purpose of applying it to the practice, we derived a following formula“W=k_??_C+N±u_??_m_??_C/N±v_??_n±w”, u, v and w are corrective ter ms respectively.
In the above formula we can consider 8-cases according as whether u, v, and w are jointly or separately zero or not.
We applied one of then “W=k_??_C+N_??_m_??_C/N_??_n” which is the most analogous one to the ideal case, on the certain conditions, to some experimental results, acquired in 1934 with other aim, in regard to the eggplant “Sinkuro”. In this case, fresh weights were used as W, total carbohydrates as C, and total nitrogen as N, though it is not necessary to be fixed as they stand, in abosolute amount per one with gram unit.
We found fairly accurate coincidences between observed values of their fresh weights and calculated values of them.View full abstractDownload PDF (2964K)
