Dickson Quality Index: relation to technological impact on forest seeds

Arthur Novikov,
Siarhei Rabko,
Tatyana Novikova
et al.

Abstract: A comprehensive indicator of predicting the quality of planting material at the time of planting – the Dickson quality Index (DQI) – is currently widely represented in studies of the growth and development of forest crops, but is not limited to them. Based on the systematization of data to a depth of 10 years returned by the term [Scholar Query = "Dickson quality index"], on the dynamics of the Dickson quality index depending on the criteria of technological impact on seeds and seedlings (seedlings), a hierarc… Show more

“…The interaction between RCD and SH will make it possible to predict the quality indicators of the seedlings: for example, the seedling sturdiness quotient (SH RCD-1) included in the Dickson Quality Index [55] as well as the possibility of excluding the operation of measuring the height of the seedling using only the RCD measurement. Moreover, a close correlation between these indicators, as shown in a recent study by Jiang et al [56], may contribute to the selection of the best trees.…”

“…The dataset allows for correlation and regression analyses of the effect of individual seed parameters on the indicator of seed sowing qualities, and can also be linked to other datasets in the FLR Library [2] to generate summary queries to predict the effect, for example, geometric parameters on 50-day container germination The tabular dataset includes the results of direct measurements of biometric parameters (height and diameter of the root neck) and bio-mass parameters of the underground and aboveground parts of the plant in the wet and dried state of container-grown seedlings obtained from these seeds. Also, based on the calculation of known ratios (for example, HDR -Height Diameter Ratio) between these parameters, the dataset presents integral indicators of the Dickson quality index DQI [6], the compactness index CP, the seedling health index SHI, the root quality index RQI. The dataset allows for correlation and regression analyses between these parameters, and can also be linked to other datasets in the FLR Library [2] to generate summary queries to predict the effect, for example, of VIS-spectrometric properties of seeds on DQI.…”

“…The quality of the seeds is closely correlated with their spectrometric properties. Moreover, the effectiveness of performing a group of seeding operations (including aerial seeding [231] on hard-to-cultivate areas) depends on the quality of seeds [3,6,12,13,34,72,79,85,89,107,111,115,139,143,175,203,217,[223][224][225][226][227][228][229][230].…”
