Dioecious nature of a plant shows variations in male and female individuals of that species, due to their differential role in sexual reproduction. So it is evident for them to have different metabolite stock in various stages of their life. Hippophae salicifolia D. Don. is a deciduous and dioecious plant species with its immense livelihood, health, and ecological potential. Focussing on the dioecious nature of this plant species male and female individuals of the H. salicifolia were screened for primary metabolite contents viz. Total soluble protein content (TSPC), total free amino acid content (TFAAC) and Carbohydrates (total soluble sugars content-TSSC and total soluble starch content-TSStC) content in different growing seasons of the year. For this leaves and buds of male and female plants were selected during active and dormant seasons respectively. Variations were observed in primary metabolites in all studied months in leaves and buds of the male and female plant. TSSC in female leaves was lower in May and July whereas it was higher in September and November than male leaves. TSPC were found higher in male leaves than female leaves in all observed month except November. TFAAC in male was most elevated in September whereas it was highest in November in female leaves. Carbohydrate, protein and free amino acid contents were found higher in winter buds which help the plants to cope up with the harsh and chilled winter conditions. During dormancy releasing period, buds showed higher TSSC, lower TSStC, higher TSPC, and lower TFAAC.

沙棘D. Don雌雄植物主要生化物质的物候变化

由于雌雄异株在有性生殖中的不同作用，其雌雄异株的性状显示出该雌雄个体的变异。因此，很明显，他们在生活的各个阶段都有不同的代谢产物。沙棘salicifolia D.唐。是一种落叶和雌雄异株的植物，具有巨大的生计，健康和生态潜力。集中在这个植物物种雌雄个体的雌雄异株性质H.柳叶筛选初级代谢物含量，即。一年中不同生长季节的总可溶性蛋白含量（TSPC），总游离氨基酸含量（TFAAC）和碳水化合物（总可溶性糖含量-TSSC和总可溶性淀粉含量-TSStC）。为此，分别在活跃和休眠季节选择雄性和雌性植物的叶子和芽。在所有研究月份中，雄性和雌性植物的叶和芽中初级代谢产物均发生了变化。雌叶中的TSSC在5月和7月较低，而9月和11月中的TSSC高于雄叶。除十一月份外，在所有观察月份中，雄性叶片中的TSPC均高于雌性叶片。男性的TFAAC在9月最高，而11月的女性叶片最高。糖类，在冬芽中发现蛋白质和游离氨基酸含量较高，这有助于植物应对严酷和寒冷的冬季条件。在休眠释放期间，芽显示出较高的TSSC，较低的TSStC，较高的TSPC和较低的TFAAC。
