Studies On The Nutritive Substance Of Phenological Period And Different Growth Stages Of 4 Species Of Allium Phenophase

The materials were Allium ramosum L.,Allium mongolicum Regel,Allium macrostemon Bunge.and Allium tenuissimum L. and the study observed phenophase and measured off their growing phases, analyzed the nutrients component of their leaves, and observed the dynamic change of the growing indexes, for example the number of leaves and the height of the plants. The results showed that:1 The growing phaseses of the four plants can be measured off :sowingdate, seed germination, seedling, blooming-growth period, declining period; germination period, returning green stage, bolting, flowering and seed maturation.2 The seed germination of A. ramosum L. and A. macrostemon Bunge. was at the first ten days of June, and the A. mongolicum Regel and A. tenuissimum L were at the middle ten days of June; the seedling of A. ramosum L. , A. macrostemon Bunge. and A. mongolicum Regel was at the middle ten days of June; but the A. tenuissimum L was at the last ten days of June; the blooming-growth period of A. macrostemon Bunge. and A. mongolicum Regel was at the last ten days of June, but the A. ramosum L. was at the first ten days of July, and A. tenuissimum L was at the middle ten days of July; the declining period of A. ramosum L., A. mongolicum Regel and A. macrostemon Bunge. was at the first ten days of October, the A. tenuissimum L was at the middle ten days of October.3 The germination period of A. ramosum L., A. macrostemon Bunge.and A. tenuissimum L. was at the first ten days of March, the returning green stage of A. mongolicum Regel was at the middle ten days of March, and the A. mongolicum Regel was at the middle ten days of March and at the last ten days of March.; the bolting period of A. macrostemon Bunge. A. tenuissimum L. was at the middle ten days of May, but the others of them was at the last ten days of May, the flowering period of A. tenuissimum L. was at the last ten days of June, the A. ramosum L. and A. mongolicum Regel was at the first ten days of July, the A. macrostemon Bunge. was at the middle ten days of July; the seed maturation of A. mongolicum Regel and A. tenuissimum L. was at the middle ten days of August, but the others was at the last ten days of August.4 The fitting period of A. ramosum L. leaves ranged from April to July, the A. mongolicum Regel ranged from June to July, A. macrostemon Bunge. Regel ranged from May to July, A. tenuissimum L. ranged from April to June, but the growing pinnacle of four plants ranged from June to July by the height of plant and so on. 5 The maximal protein content of A. ramosum L., A. macrostemon Bunge.and A. tenuissimum L. was 3.01,2.54,4.18 mg·g^-1 at seedling period, but the maximal protein content of A. ramosum L., A. macrostemon Bunge.and A. tenuissimum L. was 3.13 mg·g^-1 at seed maturation, the maximal amino acid content of A. ramosum L. and A. mongolicum Regel was 6.69,3.50 mg·g^-1 at seed maturation, but the A. macrostemon Bunge. was at flowering period, the A. tenuissimum L. was at bolting, the content was partly 2.97,15.33 mg·g^-1; The maximal soluble sugar content of A. ramosum L., A. macrostemon Bunge.and A. mongolicum Regel was 1.00%,1.41%,1.75% at bolting, but the maximal sugar content of A. tenuissimum L. was 0.64% at seed maturation; The maximal starch content of A. ramosum L., A. tenuissimum L. and A. mongolicum Regel was 0.35%,0.29%,0.27% at bolting, but the maximal sugar content of A. macrostemon Bunge.was 0.64% at flowering.The study provided the academic help for planting and managering and exploitation and utilization. And the phenophase of A. ramosum L., A. macrostemon Bunge.and A. tenuissimum L. filled up the blank, and established the basic of deeply studying and protecting, and there was significant at zoology and theory.
