Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

At the article the results of assessment of introductive value of herbs of natural flora of Mangyshlak for planting in the Mangyshlak experimental botanical garden are presented. Valued scale included 24 diagnostic signs separated into 4 groups: biological stability (hot-,dry-, winter-stability, resistant to disease and pest, substrate requirement), decorative properties and habitus (general decorative properties, length and esthetic properties of flowering and fructification), reproductive ability (seed or vegetative reproduction), practical-biological and scientific meaning (using as decorative, phytomeliorative, food, medical or technical plant). Indexes of value of herbs varied from «reduced» (V class, 45 balls) till «very high» (IX class, 83 balls). The maximum ball belongs to Tamarix ramisissimum, the minimum — Solanum persicum. The assessment of introduction value of 127 species of herbs of natural flora of Mangystau region is developed. The results are shown that «extremely low» introduction value was diagnosed 1.6 % studied species; «very low» — 3.9 %; «low» — 8.7 %; «reduced» — 15.7 %; «higher» — 22.8 %; «high» — 13.4 % and «very high» — 7.1 %. On the base of diagnostic of introduction value of herbs of natural flora is producing the collection of herbs.
