Standardization of Seed Vigor Tests
The last 30 years have led to increasing dissatisfaction by seed producers and consumers with the standard germination test as the sole criterion of seed performance potential presented on a seed label. As a result, new seed testing techniques have been formulated known as seed vigor tests that provide more sensitive measures of seed quality. The ISTA and AOSA Vigor Test Committees have been at...
متن کاملآزمون فرسودگی کنترل‌شده به‌عنوان روشی برای ارزیابی بنیه و پیش‌بینی سبز شدن بذر کلزا (Brassica napus) در مزرعه
The need to identifying seeds with low vigor and poor emergence led to introduce of various seed vigor tests. The purpose of this experiment was to assess the ability of controlled deterioration test for evaluation of seed vigor and prediction of oilseed rape seed lots emergence in the field. Samples of 19 seed lots were obtained from nineteen farmers of Razavi and Northern Khorasan Provinces...
متن کاملSeedling emergence response to temperature in safflower: measurements and modeling
Quantitative information about the response of seedling emergence totemperature for safflower (Carthamus tinctorius L.) is rare. The main objective ofthe present study was to develop a model for predicting days to emergence forsafflower as influenced by the temperature. In this regard, a field experiment with arange of sowing dates and four safflower cultivars were conducted to describe theresp...
متن کاملCommercial Seed Lots Exhibit Reduced Seed Dormancy in Comparison to Wild Seed Lots of Echinacea purpurea.
Seed germination patterns were studied in E. purpurea (L.) Moench grouped by seed source, one group of seven lots from commercially cultivated populations and a second group of nine lots regenerated from ex situ conserved wild populations. Germination tests were conducted in a growth chamber in light (40 μmol·m(-2)·s(-1)) or darkness at 25 °C for 20 days after soaking the seeds in water for 10 ...
متن کاملDifferentially expressed seed aging responsive heat shock protein OsHSP18.2 implicates in seed vigor, longevity and improves germination and seedling establishment under abiotic stress
Small heat shock proteins (sHSPs) are a diverse group of proteins and are highly abundant in plant species. Although majority of these sHSPs were shown to express specifically in seed, their potential function in seed physiology remains to be fully explored. Our proteomic analysis revealed that OsHSP18.2, a class II cytosolic HSP is an aging responsive protein as its abundance significantly inc...
