On the other hand, a significant decrease in protein content (−21%) was observed in the leaves of seedlings supplied with 5 mg C L−1 HS (Figure 3a).
For seedlings supplied with 1 mg C L−1 of humic solution, no significant difference from control was found for leaves, roots length and fresh weight.
The disruption of AtPHT1 8 or AtPHT1 9 gene function did not cause gross morphological changes in 17-day-old mutant seedlings supplied with sufficient Pi or depleted of Pi.
To fill these trays the same company also supplies seedling starting soil mix, which is finely milled, plus potting mixes that can be used for later transplanting when the seedlings mature.
Fig. 3 Altered expression of OsNPF7.2 functioned on rice seedling growth at different nitrate supply.
This experiment tested the effects of sand burial and water supply regime on seedling emergence at 15 °C25 °C (night : day) and a photon irradiance of 125 µmol m−2 s−1.
At this time, most reserve substances from endosperm began to be mobilized to supply nutriments for seedling growth, so only a small amount was degraded during the germination process [ 46].
In sterile culture, low osmolarity conditions that are suitable to suppress P5CS1 expression frequently blocked the establishment of autotrophic growth in p5cs2 mutant seedlings, whereas supply of proline or mild salt stress conditions enabled normal growth.
MS (Murashige and Skoog) growth medium (Murashige and Skoog, 1962), used by many plant circadian labs for seedling growth (including during mutant screens), supplies 100 μM FeNaEDTA.
Comparison with seedlings grown in the absence of nitrogen indicated that supply of Arg or Orn inhibited seedling establishment and use of internal nitrogen reserves in oat mutants.
