Growth and Physiological Responses of Salak Cultivars (Salacca zalacca (Gaertn.) Voss) to Different Growing Media
Bibliographic record
Abstract
The study to investigate growth and physiological responses of salak cultivars to different growing media was carried out in a greenhouse of the Institute for Horticultural Sciences, Department of Fruit Sciences of Humboldt University Berlin at Berlin. The temperature inside the greenhouse were adjusted to 20 °C/25 °C (day/night) and the relative humidity varied between 20 % and 70 %. Pure quartz sand, peat and a sand/compost mixture were tested as growth substance. The following parameters were measured: shoot dry weight, root dry weight, shoot length increment, leaf area increment, net CO2 assimilation rate (PN), leaf colour and plant mineral contents (N, P, K, Ca and Mg). Quartz sand, supplied with a complete nutrition solution was the best growing medium, whereas low pH peat was not suitable for salak seedlings due to the inhibitory growth effect. “Pondoh hitam” was the most vigorous cultivar.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
